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.

A suspension coil spring is a mechanical device that's a key part of a vehicle's suspension system: 

• FunctionCoil springs absorb shocks and vibrations from the road, which helps keep the vehicle stable and comfortable. They also help maintain contact between the tires and the road, which improves handling. 
• DesignCoil springs are made of thick steel wire that's formed into a helical coil. They can vary in size, strength, number of coils, and wire thickness. 
• InstallationCoil springs can be mounted with a shock absorber or separately. 
• PerformanceThe stiffness of a coil spring suspension can vary depending on the vehicle. For example, in trucks, the springs compress and become stiffer when the truck is loaded, which helps the vehicle bounce less. 
• MaintenanceProper maintenance and occasional replacement are important to ensure optimal performance and safety. 

The principles of the coil spring were first described by Robert Hooke in the 17th century. The first steel coil spring was produced in 1857 for an armchair.
