An accelerometer is an electro-mechanical device that measures the acceleration of motion of a pipe, equipment, or structure. This is a very useful tool for vibration engineering and is widely used to measure vibration in operating plants. The vibrating force produces an electrical signal which is captured by the sensors of the accelerometers. The use of accelerometers helps maintenance and inspection engineers understand a machine’s stability and help them monitor it to take future decisions. In this article, we will learn more about accelerometers, their working, function, selection, and types.
Working Principle of an Accelerometer
Accelerometers use sensors to sense static or dynamic acceleration forces. Static acceleration is created due to the constant forces that act on an object like gravity force or friction force. These forces are known and uniform and can easily be calculated to a large extent.
On the other hand, dynamic acceleration forces like vibration or shock are sudden, non-uniform, and can not be easily predicted. The accelerometers can detect and measure the acceleration on one, two, or three axes and convert it into electrical signals.
In general, accelerometers are equipped with internal capacitive plates. Some of these are fixed, while others are attached to minuscule springs. When an acceleration force acts upon the sensor, these plates move internally in relation to each other to cause capacitance change between them. The acceleration is then determined from these changes in capacitance.
Some other types of accelerometers use piezoelectric materials which provide an electrical charge (voltage) when placed under acceleration. There are even more types that use the piezoresistive effect, hot air bubbles, and light.
Types of Accelerometers
To efficiently serve the industry to resolve vibration problems by measuring it, there are broadly three types of accelerometers. they are:
Piezoelectric accelerometer
Piezoresistance accelerometer, and
Capacitive accelerometer.
Piezoelectric Accelerometer
This type of accelerometer uses piezoelectric materials to sense the acceleration change and is used for shock and vibration measurement. There are two types of piezoelectric accelerometers; High impedance charge output accelerometer and low impedance output accelerometer.
In a High impedance charge output accelerometer, the electrical charge produced by the piezoelectric crystal is connected directly to the measurement instruments. The charge output needs special accommodations and instrumentation. This type of accelerometer can be used even for high-temperature applications (>1200C) when low-impedance models can not be used.
The low-impedance accelerometer consists of a tiny built-in micro-circuit and FET transistor. These elements convert the electric charge into a low-impedance voltage that any standard instrumentation can easily interface. This type of accelerometer is normally used in industry. OMEGA(R) accelerometers are mainly this type of low impedance accelerometers.
Piezoresistance Accelerometer
Piezoresistance accelerometers are much less sensitive than piezoelectric accelerometers and are mainly used for vehicle crash testing. A piezoresistance accelerometer senses the amount of pressure applied to it and increases its resistance in proportion.
Capacitive Accelerometer
The capacitive accelerometer is the most commonly used type of accelerometer. An object’s acceleration is determined by the change in electrical capacitance.
Uses of Accelerometers
Accelerometers find a wide range of applications in industries. They are used in the most complex machines and even handheld devices like smartphones. Some of the real-world applications of accelerometers are listed below:
Digital Devices: To rotate the display based on the orientation of holding, smartphones, tablets, and digital cameras use accelerometers.
Vehicles: Accelerometers are responsible for triggering airbags during a vehicle accident. The accelerometers installed in the cars send a signal when it experiences a sudden shock.
Drones: Drones stabilize their orientation mid-flight with the help of accelerometers.
Rotating Machinery: The vibrations in any component in rotating machinery are measured by accelerometers and then studied to find the cause of vibration.
Industrial Platforms: Accelerometers are used to measure platform stability or tilt.
Vibration Monitoring: To monitor the vibration of any equipment, piping, or other structural component accelerometers are proved to be very useful.
Sports: The wearable devices of athletes comprise accelerometers or gyroscopes to track improvements.
Medical Industry: Physicians use accelerometers to check gain in body mass and monitor body movements. The heart rate measuring device also uses this device.
Even using accelerometers, Zoologists track animal movement inside the jungles.
Some other applications of accelerometers include the following:
The proper selection of an accelerometer depends on various parameters as listed below:
Vibration amplitude and frequency range are to be monitored.
Temperature range of the pipe/equipment requiring vibration measurement.
Size and shape of the sample to be monitored
Working environment
Presence of electromagnetic fields and noise
Requirement of Intrinsically safe or explosion-proof instruments.
Output required; analog or digital.
The number of axes for measurement; one, two, or three-axis measurement.
Maximum swing required.
Sensitivity required.
Bandwidth required.
Power requirement.

Mounting an Accelerometer
For proper mounting of any device, it is always better to read and follow the manufacturer’s manual. In general, the sensor is directly mounted to the machine’s surface where vibrations need to be measured. There are several types of mounting methods for direct surface mounting including:
Flat Magnet Mount
2-pole Magnet Mount
Adhesives (Epoxy/Cyanoacrylate)
Mounting Stud
Isolating Stud
Magnet Mounts are used for temporary mountings on ferromagnetic materials. This type of mounting allows the sensor to be easily relocated from one location to the other for multiple readings. For mounting on a curved ferromagnetic surface, two-pole magnetic mounts are used.
Adhesives such as epoxy or cyanoacrylate and threaded studs are normally considered for permanent mountings. Mounting studs provide solid reliable mountings but require the structure to be drilled and tapped.
Characteristics of an Accelerometer
All accelerometers should possess the following characteristic features:
Rugged and durable
High stiffness
Very repeatable
Wide dynamic range
Fast rise time
High-useable frequency range
Communication Interface
Accelerometers communicate over an analog, digital, or pulse-width modulated connection interface.
Analog Accelerometers show accelerations through varying voltage levels which normally fluctuate between the ground and the supply voltage level. Analog accelerometers are cheaper than digital accelerometers.
Digital Accelerometers communicate over SPI or I2C communication protocols which have more functionality and are less susceptible to noise than analog accelerometers.
Accelerometers with output data over pulse-width modulation (PWM) output square waves with a known period, but a duty cycle that varies with changes in acceleration.
What is Metal Grating? Types and Uses of Metal Gratings
Metal grating is a very useful perforated metal product widely used as floors, trench covers, mezzanines, trailer beds, scaffolding, stair treads, fencing, grills, bridges, fire escapes, and maintenance platforms in various industries. They are produced by perforating metal sheets or joining metallic bars to form a grid. Various manufacturing methods like expansion, perforation, molding, welding, etc are used to produce metal gratings.
The most common metals that are used to make metal gratings are iron, carbon steel, aluminum, and stainless steel. Metal gratings must have sufficient strength to carry the load and should have a non-slip safe surface to serve as a secure work platform.
Types of Metal Gratings
To cater to the different industry application needs, various types of metal gratings are produced. The specific type of metal grating selection depends on some parameters like:
thickness,
metal bar dimensions,
the configuration or pattern of the gaps or openings, which include oval, square, and diamond shapes.
load to be carried,
the work environment where used, etc.
In the following section, we will discuss the most common metal grating types.
Metal Grating Types
Expanded Metal Gratings
Expanded metal grating is produced by puncturing slits in a metal sheet. After the slits are cut, the metal sheets are stretched and pulled to expand them. Because of this expanding action, this type of metal grating is known as expanded metal grating. A diamond-shaped pattern with a slip-resistant surface is generated in the grating. The completed sheets are then cut to the required size to fit the application requirement. Common metals that are used to produce this type of metal gratings are carbon steel, stainless steel, and aluminum.
No waste is created while making expanded metal gratings and hence, this is very economical. The sheets have good structural strength. A Standard expanded process along with cold rolling to flatten the surface to a smooth even finish is usually used during manufacturing. Expanded metal grates are widely used in flooring, fences, security applications, steps, etc.
Bar Metal Grating or Bar Grating
This is the most common type of metal grating. Bar metal grating is constructed of parallel bars connected together to perpendicular bars using various methods like welding, riveting, press-locking, close meshing, etc. The joining method for bar grating is decided based on the thickness of the bars, the material being used, and the cost.
Steel and Aluminum are the most common metals to produce bar metal grating. Due to their high strength-to-weight ratio, they are used in industrial flooring, street drains, fire escapes, and bridges.

Wire Mesh Metal Grating
Wire mesh metal grating is also popular by names like wire cloth, wire fabric, wire grating, etc. This type of metal grating is produced by using rows and columns of intersecting wires. The popularity of wire mesh grating is due to its easy installation, high durability, flexibility, and versatility.
Depending on the manufacturer, wire mesh metal grating can be welded or woven. Welded wire metal grating is welded at locations where the row and columns intersect. On the other hand, woven wire metal grating is woven like cloth and thus has an array of intersecting wires with columns and rows going over and under at their connecting points.
Wire mesh metal grating is used for Separation and filtration, Security work, Ventilation, Screening and fencing, Material reinforcement, etc.
Perforated Metal Grating
Perforated metal grating is also known as perforated screen, perforated sheet, or perforated plate. They are produced by stamping, punching, or deforming metal sheets to create holes of a specific size, pattern, and shape. Exceptionally sturdy metals like stainless steel, carbon steel, and aluminum are used as metal sheets to make this type of metal grating. Holes are made by different metal fabrication processes like rotary pinning, die punching, laser cutting, etc.
Common applications of perforated metal grating are sound reduction, ventilation, screening, chemical purification, centrifuging, construction material development, etc.
Safety Grating
Also known as Grip Strut Grating, Safety grating provides a firm, solid, and skid-resistant walking surface. These types of metal gratings are designed to increase traction and prevent stumbling, slips, and falling. Small diamond protrusions are usually used in safety grating for greater grip and traction. The open surfaces prevent the accumulation of liquids and help in drainage and airflow. The increased grip of safety metal grating is due to the serration of the edges of the diamond openings created by cold stamping. Steel and Aluminum are the common materials for safety grating.
Compound Metal Grating
Compound metal grating is produced by combining two forms of grating and generally includes bar grating and steel plate grating. Usually, they are composed of a checkered plate sealed to the surface of a steel bar metal grating, with 3 mm to 6 mm steel plates. Compound metal grating is available in a variety of sizes and material types.
Press Locked Metal Grating
In Press locked metal grating, the cross and bearing bars are notched and pressed together and hence the name. They have a smooth even surface across the joined bars. Pressed locked metal gratings have an aesthetically appealing appearance and are generally produced from Steel and Aluminum with a wide variety of sizes and bar openings.
Common Materials Used to Make Gratings
Grating usually refers to any type of covering or frame used to cover holes, provide protection, offer support, or serve as a platform. A wide variety of materials can be used to manufacture grating. Even sturdy plastics can be used to make gratings.
In general, the metallic grating is more popular because of its strength and ability to adjust to many environmental conditions. Specialized metal gratings are used in various industries, airports, and manufacturing facilities and are very strong and durable.

How are Metal Gratings Made?
Metal gratings are typically made through a process called metal bar grating fabrication. The exact steps and techniques may vary depending on the type and application of the grating, but here is a general overview of the manufacturing process:
Material selection: The first step is to choose the appropriate type of metal for the grating, based on factors such as the intended application, load-bearing capacity, corrosion resistance, and environmental conditions. Common metals used for gratings include steel, aluminum, stainless steel, and other alloys.
Cutting the bars: Metal bars, which are the primary components of the grating, are cut to the desired length using various cutting methods like shearing, sawing, or laser cutting.
Shaping and hole punching: The metal bars are then shaped and perforated to create the desired pattern. This involves stamping or punching holes through the bars in a regular grid pattern. The hole size and spacing determine the open area and load-bearing capacity of the grating.
Joining bars and cross rods: For certain types of gratings, cross rods are attached to the main bars to form the final grating panel. Different methods like welding, swaging, or riveting may be used to securely join the bars and cross rods.
Surface treatment: Depending on the application and environmental conditions, the metal grating might undergo surface treatment to enhance its properties. This can include processes like galvanizing (hot-dip or electro), painting, or applying other coatings to improve corrosion resistance.
Cutting to size: Once the grating panels are assembled and treated, they may be cut to the required dimensions to fit the specific installation locations.
Quality control: Before being shipped to customers, the metal gratings undergo rigorous quality control checks to ensure they meet industry standards and specifications.
What are Metal Grating Sheets
Metal grating sheets are large, flat panels made from metal bars that have been welded, press-locked, or riveted together in a grid pattern. They are commonly used for various industrial, commercial, and architectural applications due to their strength, durability, and open design, which allows for efficient drainage and ventilation. Metal grating sheets are available in different materials, such as steel, aluminum, stainless steel, and other alloys, each with specific properties suitable for different environments and applications.

What is the Unified Numbering System (UNS) for Metals and Alloys?
To overcome the problems of traditional material numbering systems developed during the 1960s for distinguishing each material separately and standardize, a study was conducted. After an 18-month feasibility study and discussions with AISI, the Aluminum Association, the Copper Development Association, and the Steel Founders’ Society of America, the team recommended establishing the Unified Numbering System (UNS). The UNS numbering system is used by many engineering industries and is accepted globally.
What is a Unified Numbering System
The Unified Numbering System or UNS is a metal and alloy designation system managed jointly by ASTM International and SAE International. Each specific metal or alloy is assigned a UNS number that defines mainly its specific chemical composition, and sometimes specific mechanical or physical properties. So, the unified numbering system basically is a composition-based material numbering system where each metal/alloy is identified with a letter followed by five numbers.
Note that, a UNS number alone does not serve as the full specification of that material as it does not establish any requirements for material properties, heat treatment, form, or quality. A document SAE HS-1086 gives a cross-reference for various designation systems and the chemical composition of materials. Currently, there are more than 5200+ UNS designations for different metals and alloys.
Difference between UNS number and Material Specification
A UNS number only provides a specific chemical composition. The full material specification is not provided in the UNS number. Other material requirements such as mechanical properties, heat treatment, form, purpose, and testing methods are specified in the respective material specification. Various trade and professional organizations prepare these material specifications. Within a material specification, a number of different UNS numbers may be included.
UNS Number Format
Each UNS number is structured with a letter followed by five digits that designate the composition of the material. They have 18 series to identify metals and alloys. Out of these 18 series, 9 are for ferrous metals and alloys and the other 9 are for non-ferrous metals and alloys.
Letters used in the unified numbering system are A for Aluminum and Aluminum alloys, C for copper and copper alloys, D for specified mechanical property steels, E for Rare earth and rare earthlike metals and alloys, F for cast Irons, G for AISI and SAE carbon and alloy steels, H for AISI and SAE H-steels, J for Cast steels, K for Miscellaneous other steels and ferrous alloys, L for Low-melting metals and alloys, M for Miscellaneous nonferrous metals and alloys, N for Nickel and nickel alloys, P for Precious metals and alloys, R for Reactive and refractory metals and alloys, S for Stainless Steels, T for Tool Steels, W for Welding filler metals, and Z for Zinc and zinc alloys.
The first 3 digits usually match older 3-digit numbering systems, while the last 2-digits indicate modern variations. To give an example, Stainless Steel Type 310 in the original 3-digit system became S31000 in the UNS System. The more modern low-carbon variation, Type 310S, became S31008 in the UNS System. Sometimes the suffix digits represent a material property specification. For example, “08” in UNS S31008 represents the maximum allowed carbon content of that material is 0.08%.
Examples of Unified Numbering System for Common materials
Some of the common materials and translations to other standards are:
UNS S31600 is SAE 316
UNS K11547 is T2 tool steel
UNS S17400 is ASTM grade 630, Cr-Ni 17-4PH precipitation hardened stainless steel
UNS S30400 is SAE 304, Cr/Ni 18/10, Euronorm 1.4301 stainless steel
UNS S31603 is 316L, a low-carbon version of 316. The digit “03” was assigned since the maximum allowed carbon content is 0.03%
UNS C90300 is CDA 903

Table 1: UNS Numbering System for Metals and Alloys
Importance of UNS (Unified Numbering System)
Various trade associations, societies, and individual users and producers of metals and alloys use the UNS system to avoid confusion. The system provides a uniform approach and proficient indexing which helps in record keeping, data storage, retrieval, and cross-referencing. Using UNS numbers metal and alloy identification becomes much easier.
Aluminum pipes and tubes are soft and ductile and their color resembles the color of silver. Due to its low density and lightweight along with decent corrosion resistance capability, aluminum pipe and tubes are preferred in many applications like healthcare, aerospace, recreation products, machine parts, automobile, and transportation hydraulic systems, solar power, refrigerators, and air conditioning systems, brakes, fuel lines, frames, etc. When exposed to a corrosive environment, aluminum forms a passive coating that stops further corrosion. Pure Aluminum is not used for industrial piping applications. Whatever aluminum pipe is commercially available is basically made from aluminum alloys combined with alloying elements like zinc, copper, manganese, magnesium, and silicon.
Aluminum Pipes & Tubes vs Steel Pipes and Tubes
Strength: Aluminum pipe and tubes have lower strength as compared to steel piping and tubing. Both the yield strength and tensile strength of aluminum pipes are much lower compared to steel pipes. Roughly Steel pipes are 3 times stronger than aluminum pipes.
Density and Material Weight: For the same size and thickness, Aluminum pipes and tubes are lighter as compared to steel pipes. The density of aluminum pipes is lower than steel pipes.
Manufacturing: Aluminum Tubing & Piping are manufactured mainly by extrusion process by forcing a die whereas for steel piping extrusion process is mainly employed for small diameter pipes. Large-diameter steel pipes are usually welded. Aluminum pipes can also be made using spiral welding and the electric resistance welding process.
Alloys Used in Aluminum Pipes and Tubes
Common alloying additions with aluminum are magnesium, manganese, copper, zinc, and silicon. Each of these alloying elements adds different properties to the base metal. The aluminum alloy grades that are popular as pipe and tube are 2024, 3003, 6005, 6041, 6061, 5052, 6063, 6064, 6082, 6105, 6262, 6351, and 7075. ASTM B241/B241M governs the specification of Aluminum pipes and tubes.
Aluminum Pipe Codes and Standards
The piping system is designed following ASME B31.3. Various ASTM codes for aluminum pipe and tube specifications are:
ASTM E155 (Aluminum casting),
ASTM B210 (Seamless tubes),
ASTM B241 (Seamless Pipe and Seamless extruded tubes),
ASTM B345 (Seamless pipe and extruded tube for oil and gas transmission and distribution piping),
ASTM B361 (Aluminum and Aluminum alloy welded fittings),
ASTM B247 (Aluminum fittings),
ASTM B491 (Extruded round tubes for general-purpose applications),
ASTM B547 (Formed and arc welded round pipe and tube)
Aluminum Pipe Sizes
A wide range of Aluminum pipe and tube sizes are available. Commercially available common aluminum pipe size ranges are 1/8″ to 12″. However, custom sizes can easily be manufactured based on requirements.
Common aluminum tube sizes range from 1/16″ to 3″
Aluminum tubes are usually used for their lightweight, thermal and electrical conductivity, and corrosion resistance. Alloy grades 7075, 6061, and 2024 are used inside aircraft assemblies as they have a high strength-to-weight ratio and good fatigue resistance.
Applications requiring more strength and corrosion resistance use Alloy 3003. When multiple welded joints are expected, a highly weldable 5052 can be a good choice.
Proper heat treatment is very important for aluminum alloy pipes and tubes as the characteristics of the alloy are determined by the heat treatment.
Parameters for Choosing Aluminum Tubing & Piping
The selection of Aluminum tubing and piping depends on various factors. Some of them are:
The shape of Aluminum Tubing & Piping
Even though circular pipes and tubes are common and widely used, aluminum tubes are available in various other shapes like rectangular, oval, square, or custom shapes. However, other shapes are costly as compared to regular round shapes.
Process parameters
The selection of every metal pipe and tube is governed by various process parameters as mentioned below:
Pressure Rating– this indicates the maximum or minimum pressure the pipe and tubing can withstand. Depending on the pressure the pipe thickness also varies.
Minimum Bend Radius Rating– this informs the amount of deformation a tubing’s cross-sectional area can go through.
Maximum Vacuum Pressure– If the aluminum pipe or tube will be subjected to vacuum pressure.
Temperature Range– The complete range of temperatures (Maximum and Minimum) that the fluid and material will experience.
Characteristic Features of Aluminum Tubing & Piping
Important characteristics that are usually required for aluminum pipes and tubes are:
Finned or Fluted– Aluminum tubes with fins or flutes can easily dissipate heat. For air conditioners, refrigeration, and heat exchanger applications finned tubes are required.
Serializability– Aluminum tubes in certain applications need sterilization using gamma irradiation, dry heat chemical, disinfection, and autoclaving.
Coiled or Spiral– Aluminum tubes must be flexible enough for running in a wrapped reel spring or format.
Multi-Layered– Multilayered tubes are more robust and durable.
Finish of the Aluminum Tubing & Piping
Aluminum pipes and tubes are finished and coated with a definite type of finish, like:
Galvanized– A zinc layer is added for additional corrosion resistance.
Bright Finish– Mirror-polished surfaces are created to have a shiny look.
Plated– Thin layer of another metal is deposited to improve its corrosion resistance and conductivity.
Painted– Pipes and tubes are painted to increase corrosion resistance or for identification purposes.
Aluminum Pipe Fittings and Components
Aluminum pipe fittings connect with aluminum pipe to create secure, leak-free connections. Similar to steel pipes, aluminum pipe fittings are also required for any directional changes or size changes, or branch connections. Almost all variants of aluminum pipe fittings are available similar to steel pipe fittings. They are produced either by casting or forging and usually have threaded, welded, or flanged end connections. Common aluminum pipe fittings and components are:
Managing expensive and labor- ferocious operations to smart software sounds like an easy task, but for EPC companies with extremely complex megaprojects, any functional changes bring time, plutocrats, and trouble to reciprocate. As a result, the EPC sector is hesitant to go through digital metamorphosis. But these days, there’s new instigation behind engineering software enterprise. In fact, the previous year, 76 engineering and construction directors in a Deloitte postelection poll invested in digital tech time. So, what’s driving the new commitment to technology?
COVID-19 Accelerated Digital Transformation
For numerous EPC enterprises, the pandemic twisted their hands. Companies had to deal with a remote workforce, and they demanded increased safety considerations for onsite jobs. The fresh hurdles extended design timelines by over 300%.
The application of digital tools that sped up processes while maintaining safety and quality, is a necessity if enterprises wanted to stay in business. A remote pool needed the relinquishment of collaboration, cloud, and cybersecurity operations. Limited labor forced associations to do more with fewer people, which resulted in the implementation of labor-saving technology to make the utmost of experts ’ time.
For numerous companies, the experience of planting results as a response to COVID- 19 motivated plans for continuing the digital metamorphosis. Numerous companies extended their cooperative and labor-saving tech to further design phases. They started taking advantage of artificial intelligence(AI), machine learning (ML), and smart security.
Some companies are also starting to profit from further sophisticated labor-saviors, for example; independent vehicles to handle figure tasks and cover the design point, 3D printing for the custom corridors, and natural language processing(NLP) to parse vast quantities of paperwork and create reports.
EPC Market Shifts Introduce Challenge and Opportunity
Along with the hurdles the pandemic brought, EPC enterprises are scuffling with other market problems that started well before COVID-19 and continue to grow. To elaborate, in the energy sector, there are more systems for sustainable sources similar to wind and solar. Along the same lines, in the U.S., any major construction design must comply with environmental, social, and governance( ESG) programs. The sector players are changing as well. Non-traditional construction enterprises, backed by ultramodern backing have entered the game, especially in new energy sectors like solar.
To meet these challenges EPC enterprises are looking for collaborators, who can give the demanded expertise. Hydrocarbon Processing magazine predicts, “ In 2030, possessors and contractors will have evolved their approach to constricting toward fostering more open and cooperative connections, with better alignment across parties toward a greater outcome for the project overall, not just individual players. ”
But partnerships bring their own difficulties. As the size of the project platoon increases, it’s harder to manage communication and workflow, raising the threat of cost and schedule overruns. Plus, more players induce further documents, plans, and designs that need to be reused, stored, penetrated, and participated in by the right people at the right time.
EPC companies who successfully handle the present issues will manage not only hurdles but openings for digital transformation that manage a large meta eco-system while delivering improved effectiveness and lesser pungency. With the proliferation of documents, plans, designs, and design data, enterprises are enforcing engineering software to centrally manage and dissect data and documents from distant sources. And virtual models using the structure information operation frame will help engineers across the platoon and the world coordinates the designs, plans, and status for complex shapes.
Companies are also applying technology that enables slender, brisk design completion. For instance, the technical bi-tabulation process(TBE) has long needed engineers to organize and assess dozens of supplier quotes in a labor-ferocious, time-enervating process. However, applications with NLP can read reams of documents, classify the details and induce reports so engineers can concentrate on analysis. Technology similar to NLP not only saves time and plutocrat but improves the TBE results, helping engineers find the optimal supplier selection.
In the quest for time savings and threat mitigation processes, EPC providers will focus on AI-driven workflow to coordinate and manage all the processes, dwindling the liability of expensive miscommunications. And as digital data piles up, data analytics powered by machine learning will turn one experience into a companion for uninterrupted advancements.
Digital Success Encourages Further Digital Transformation
Once EPC brigades dip their toes into the digital waters, the success of original systems will propel them indeed further. According to Deloitte,
“Benefits [of engineering software] are expected to include as much as a potential 10% to 30% reduction in engineering hours, up to 10% reduction in build costs, and up to 20% reduction in operating costs, improving overall margins for E&C firms throughout the entire project life cycle.”
As more companies realize these benefits, they’ll snappily move to extend them, which increases pressure on the sector in general. Players who want to stay in the game will have to get digital.
In fact, technology relinquishment may be the crucial factor separating winners from also-rans in the forthcoming EPC world. Those who get a jump start on the overall digital transformation will realize a first-mover advantage. Numerous clients in fact view digital-centric EPC companies as more dependable and less parlous than others.
Companies that’ve digitized the utmost of their processes and formalized data storehouse will be in a better place, to take advantage of data collection and analysis across the enterprise. Observers on the job point will feed into AI-driven schedule optimizers who insure the outside effective use of workers and outfits. 3D definitions will help contrivers from remote locales unite ahead and during the figure. AI systems will identify safety pitfalls, and augmented reality (AR) will help offsite experts consult with onsite masterminds about problems or repairs.
What is a Forklift? Working and Types of Forklifts for the Construction Industry
In the oil and gas construction industry, efficient material handling is critical. Forklifts play a vital role in ensuring that operations run smoothly, safely, and efficiently. These versatile machines are not only essential for transporting materials but also contribute to maintaining productivity and safety standards on construction sites. Forklifts are one of the most useful and powerful construction vehicles on any job site for handling materials and carrying heavy loads in a safe and secure way. Their versatility makes them indispensable, and so forklifts are found in all construction and building sites wherever heavy loads are to be moved. In this article, we will explore more about industrial forklifts, their types, components, working, and selection.
What is a Forklift?
A forklift is a powered industrial truck designed to lift, move, and transport heavy materials over short distances, typically within warehouses, construction sites, and manufacturing facilities. Equipped with two fork-like prongs at the front, forklifts can lift loads by inserting the forks beneath them and are powered by either internal combustion engines or electric batteries. Their versatility and maneuverability make them essential for various material handling tasks, including loading and unloading goods, organizing inventory, and facilitating efficient operations in diverse industries.
Types of Forklifts
There is a wide range of industrial forklifts to choose from. The most common types of forklifts are listed below:
Warehouse Forklift
Side Loaders
Counterbalance Forklift
Telescopic Forklifts
Heavy-duty Forklifts
Rough Terrain Forklifts
Reach Fork Trucks
Pallet trucks
Walkie Stacker
Order Picker
Warehouse Forklift
It is quite clear from the name itself that the Warehouse forklift is widely used in most warehouses, factories, and job sites. Warehouse forklifts are one of the most common working vehicles used for loading and unloading inventory. Resembling like a golf cart with two forks extending from the front, this type of forklift usually has a loading capacity of up to 5 Tonne.
Side Loaders
Side loaders are widely used in narrow spaces where navigation and turning are very difficult. They are basically a subtype of warehouse forklifts and are generally found in manufacturing industries. The operator stands in a sideways compartment while using this type of forklift. The side loader has the capability to lift and carry the material in the same direction without turning.
Counterbalance Forklift
Counterbalance forklifts have forks in the front and the counterbalance weight in the back. They don’t have any extended arms and they can be driven right up to the material. From the front of the vehicle, the forks directly come out which makes grabbing the inventory easier.
Counterbalance forklifts are produced in electric, gas, or diesel-powered models. Mitsubishi, Crown, and Toyota are some of the popular manufacturers. The 3-wheel variant of the counterbalance forklifts helps the driver to turn easily in circles.
Telescopic Forklifts
This type of forklift is also popular by names like reach forklift, telehandler, or teletruck. Telescopic forklifts are a combination of a forklift and a crane. With a boom and an extending arm, the telescopic forklifts can reach far into the back of delivery trucks and carry materials much higher and farther than usual forklifts.
Their twin forks help in moving pallets off the ground. Companies like JCB, Genie, Bobcat, Haulotte, and Caterpillar manufacture a variety of telescopic forklifts.
Industrial Forklifts or Heavy Duty Forklifts
Also popular as large capacity forklifts, this type of forklift can lift much heavier loads than the standard forklifts. Usual heavy-duty industrial forklift models can lift a maximum weight of 30,000 lbs. However, similar to telehandlers, they cannot lift at awkward angles. NACCO and Mitsubishi are the big names that produce Industrial forklifts.
Rough Terrain Forklifts
Rough Terrain Forklifts are also called Straight mast forklifts. They widely find outdoor applications on uneven, unstable surfaces. Having thick tractor-style pneumatic tires, rough terrain forklifts doesn’t slip on wet or slippery surfaces. Their sturdy tires are difficult to puncture with nails or sharp rocks, and they help with stability and balance while carrying heavy loads on uneven ground.
Rough terrain forklifts are ideal for construction sites. With a traditional straight mast or a telescoping mast, they can handle a weight capacity of 6,000 to 12,000 pounds.
Reach Fork Trucks
Mostly used in warehouses, reach fork trucks can extend their forks out beyond their stabilizing legs into racks. Suitable for tight spaces, this type of forklift can maneuver with narrow aisle ways and lift loads to high heights.
As they have heavy electric batteries and stabilizing legs, reach fork trucks provide inherent stability and do not need counterbalance weight.
Pallet trucks
Pallet Trucks or pallet jacks or pump trucks are specially designed forklifts without any power source. They are small in size and have the limited load-lifting capability. As they are easy to use and fit well into small tight spaces, they are used to raise the pallet enough to clear the ground.
Walkie Stacker
This type of forklift has a unique appearance and provides specific utility. They don’t have cabs and the operator needs to walk behind the stacker to operate.
Order Picker
A sub-type of walkie stacker, order pickers pick the material from storage and deliver it. This type of forklift is designed to lift the operators up. They are produced in versatile designs to handle various sizes.
Depending on fuel option and application, Occupational Safety and Health Administration (OSHA) categorizes forklifts into seven classes as listed below:
Class I – Electric Motor Ride Truck
Class II – Electric Motor Narrow Aisle Truck with Battery as a fuel source
Class III – Electric Motor Hand Truck with Battery as a fuel source
Class IV – Internal Combustion Engine With Cushion Tires with Gas or Diesel as a fuel source
Class V – Internal Combustion Engine Trucks With Pneumatic Tires with Gas or Diesel as a fuel source
Class VI – Electric and Internal Combustion Engine Tractors with Battery, Gas, or Diesel as a fuel source
Class VII – Rough Terrain Forklift Truck with Gas or Diesel as a fuel source.
Components of a Forklift
To perform its task effectively a forklift has a variety of components as listed below:
The truck frame serves as the base for all other components.
A counterweight attached to the rear part to counterbalance the lifted weight.
Power Source
A carriage that fastens to the mast rails and moves up and down.
The mast consists of interlocking rails to give horizontal control.
Refer to Fig. 1 below that shows the parts of a forklift.
Fig. 1: Forklift Parts
Working of a Forklift
To carry heavy loads, forklifts use a combination of hydraulic systems and pulley systems.
The hydraulic system uses a series of pistons, cylinders, and hydraulic fluid to lift and lower the loads. A skilled forklift operator uses the lift handle to raise or lower the loads. The hydraulic fluid creates the necessary pressure through its pump, piston, and cylinder mechanism. The fluid pressure creates an upward force to move the piston upwards.
The fork is attached to a pair of roller chain pulleys. When the hydraulic pistons force the mast in the upward direction, the gears on the mast are pressed against the roller chains which move the mast up and pull the fork in the upward direction. Two controls; steering and lifting help the operator to lift loads and move.
Selecting a Forklift
As a wide range of forklifts is available it is really difficult to choose the right forklift. While selecting the ideal forklift for the project, various parameters must be considered. Some of these are:
Load-bearing Capacity–The weight required to lift and at what height.
Space Availability– the forklift selection must consider the space available in the area where it will be used. The height of doorways and openings must be considered.
Power Source– whether electric-powered, battery-powered, or gas/oil-powered.
Surface Terrain–Find out if the ground surface is even or rough.
Stability of the Job site– If the ground can sustain the forklift.
Characteristics of a Forklift
Forklifts are usually characterized by three factors:
Lift Capacity– The amount of weight the forklift can safely handle without losing its stability.
Load Centre– The distance from the forks to the center of gravity of the carried load. Depending on height, weight, lift angle, and tilt angle the load center varies.
Stability– The forklift should not be tipped while carrying heavy loads. Usually counterbalance weights are used to increase stability.
