Definition:
Heavy duty springs are compression, extension, or torsion springs with a great amount of force. They have large wire diameters from 1/4" (inch) to 1" (inch) in thickness and are required when the spring needs to support a large amount of load in a mechanism.
Heavy Duty Compression Springs
Heavy duty compression springs are used in mechanisms that require a great amount of force to be exerted on the spring. You may find heavy duty compression springs in heavy construction machines, agricultural equipment, industrial equipment and oil field equipment.
These springs may be found in stock through a stock compression spring catalog but could also be custom-made if you aren't able to find what you need in stock.
Heavy Duty Extension Springs
Heavy duty extension springs are required when a device needs a large amount of load to be pulled on the spring. They can be found in heavy hydraulics, heavy vehicles, or metal working machinery.
Heavy duty extension springs may also be found in stock extension spring catalogs or be custom made in case that you have a mechanism that requires a more exact design to meet your mechanism's specific needs.
Heavy Duty Torsion Springs
Heavy duty torsion springs are usually found in lift-gates, hatches, or lids. They are able to exert large amounts of torque when a torque load is placed on the legs. Their function in a truck's lift gate, for example, is to assist the user to support the weight of the gate safely while pulling it down. They also assist the user in lifting the gate back to its original position with minimal human force.
Heavy duty torsion springs can be custom-made to match the torque that you require and to fit your application properly. There is also a stock torsion springs catalog you may search through to find your heavy duty torsion spring.

Heavy duty springs are large wire diameter springs made for big heavy industrial applications that are typically used in demanding applications where ordinary smaller springs would fail under the strain. They come in various types, including heavy duty compression, extension, and torsion springs, each tailored to specific heavy force requirements and applications. Heavy duty springs are characterized by their large wire diameters, which range from 1/4" to 1.250" in thickness, providing the necessary strength and durability, ensuring that the springs can handle heavy duty tasks without deformation or failure. These springs are essential in industries, from construction to agriculture, ensuring the safe and efficient operation of heavy machinery and equipment.
Heavy duty compression springs are indispensable in applications requiring substantial force exertion. These springs are designed to compress under load, storing potential energy that can be released when the load is removed. Here are some specific heavy duty spring applications:
- Construction Machinery: These heavy duty springs are used in equipment such as bulldozers, cranes, and excavators to absorb shock and maintain stability under heavy loads. The large springs help to dampen vibrations and protect delicate components from damage.
- Agricultural Equipment: In tractors, plows, and harvesters, heavy duty compression springs are used to support heavy loads and provide smooth operation. They help in handling the rough and uneven terrain encountered in agricultural fields.
- Industrial Machinery: Equipment like presses, stamping machines, and conveyors rely on heavy duty compression springs to manage the force exerted during operation. These springs ensure consistent performance and reduce wear on the machinery.
- Oil Field Equipment: In the oil and gas industry, these heavy duty springs are used in drilling rigs and pumps to withstand the harsh and demanding conditions. They provide the necessary force to operate equipment effectively and safely.
While many heavy duty compression springs are available in stock through stock spring catalogs, custom-made heavy duty spring options are also available to meet specific needs when stock springs do not suffice. Customization ensures that the heavy duty springs are perfectly tailored to the application, providing optimal performance and safety.
When a device requires a large significant load to be pulled, heavy duty extension springs are the solution. These springs work by extending under load and returning to their original shape when the load is removed, storing energy in the process. Here are some specific applications:
- Hydraulic Systems: These heavy duty extension springs are used in hydraulic systems to manage the force exerted during operation. They help in maintaining pressure and ensuring smooth and efficient performance.
- Vehicles: In trucks, buses, and other heavy vehicles, heavy duty extension springs are used in the door and lift system to provide weight relief for these systems. They also help in managing the force exerted when the vehicle is loaded or unloaded.
- Metalworking Machinery: Equipment like lathes, milling machines, and presses use heavy duty extension springs to control movement and maintain tension on belts and linkages. These heavy duty springs ensure precision and accuracy in metalworking processes.
Similar to compression springs, heavy duty extension springs can be sourced from stock spring catalogs or custom-designed to meet the precise specifications of your mechanism. Custom heavy duty extension springs ensure that the specific load and operational requirements are met, providing reliable performance in demanding environments.
Heavy duty torsion springs are typically used in applications such as lift-gates, hatches, or lids, where they provide substantial torque when a load is applied to the legs. These springs work by twisting and exerting a rotational force, which is essential for applications requiring controlled rotational motion. Here are some specific applications:
- Lift-Gates: In trucks and utility trailers, torsion springs are used in lift-gates to assist in lifting and lowering heavy gates. The heavy duty torsion springs help in reducing the weight of the gate or the lid and the effort required by the user and reduce the risk of injury by the user thus making the gate or the lid lighter.
- Hatches and Lids: In industrial and commercial settings, heavy duty torsion springs are used in hatches and lids to provide controlled opening and closing. They help in reducing the weight of the lids by absorbing there weight and ensure smooth and reliable operation.
- Garage Doors: Heavy duty torsion springs are essential in garage door systems to counterbalance the weight of the door. They provide the necessary torsional force to lift the door smoothly and safely.
- Aerospace Applications: In aircraft and spacecraft, heavy duty torsion springs are used in aerleoron mechanisms to control movement and provide stability to the aereolon. These heavy duty torsion springs are designed to withstand extreme conditions and provide reliable performance.
Customization options are available to ensure the heavy duty torsion spring matches the required torque and fits the application properly, though stock online torsion springs catalogs also offer a variety of options. Custom heavy duty torsion springs can be designed to meet specific torque requirements and operational conditions, ensuring optimal performance and safety.
Designing heavy duty springs involves careful consideration of various parameters to ensure that the springs can perform reliably under significant loads and harsh conditions. The process can be complex, requiring precise calculations and a deep understanding of mechanical spring design principles. Acxess Spring simplifies this process with our advanced tools and expert guidance. Here’s an expanded look at the key aspects of heavy-duty spring design, including formulas and examples.
Key Parameters in Heavy Duty Spring Design
- Spring Rate also known as the spring constant (k), is a crucial parameter that defines the stiffness of the spring. It is calculated using the formula:
k = Gd^4 ÷ (8D^3 * n)
where:
- G is the modulus of rigidity of the material (for Stainless Steel 302, G≈11.2×10^6 psi),
- d is the wire diameter,
- D is the mean diameter (outer diameter - wire diameter),
- N is the number of active coils.
Example Calculation: For a spring with:
| Part Number | |
| Outer Diameter |
2.975 inches |
| Inner Diameter |
2.225 inches |
| Wire Diameter |
0.375 inches |
| Mean Coil Diameter |
(2.975 + 2.225) ÷ 2 = 2.6 inches |
| Free Length |
5 inches |
| Solid Height |
3.375 inches |
| Total Coils |
9 |
Substitute the values
k = 11.2 × 10^6 psi × (0.375 inches)^4 ÷ 8 × (2.6 inches)^3 × 9 = 199.90203 lbs/in
2. Applying Hooke’s Law The formula F=kx is a fundamental equation in spring mechanics, also known as Hooke's Law. It states that the force (F) exerted by a spring is directly proportional to the travel or deflection (x) of the spring from its equilibrium position, with k being the spring constant (or spring rate). Here, we'll use a deflection (x) of 1.5 inches.
Calculation:Using the formula F=kx:
F = k × x
Substitute the given values:
F = 199.90203lbs/in × 1.5inches
Perform the multiplication:
F = 299.853lbs
By applying Hooke’s Law, we have determined that the force exerted by the heavy duty spring when it is compressed by 1.5 inches is 299.853 pounds.
3. Maximum Travel (MT) refers to the greatest distance the spring can compress or extend without exceeding its elastic limit or deformation.
4. To find the Max Travel for your spring go to Spring Creator 5.0 and input your spring dimensions and click calculate, In the specs tab you will find the max travel (MT) for your spring. Never go past the max travel for if you do the compression or extension spring will not return to its original lenght and the spring will deform and take a set. Going past the maximum travel point you will lose spring load and force and the spring can possibly break. Never ever go past the maximum travel of your spring.
5. Maximum Load The maximum load (ML) is the highest amount of force that the spring can safely handle without permanent deformation or failure. It can be calculated using the formula:
ML = k × MT
where:
- k is the spring rate,
- MT is the maximum travel.
Example Calculation: Using the given values:
- Spring Rate (k) = 199.90203 lbs/in
- Maximum Travel (MT) = 1.6250 inches
ML = 199.90203 × 1.6250 = 324.8408 lbs
