What Is a Spring Caster?
A spring caster is a caster, or wheel, to which springs are attached. The purpose of a spring caster is to increase the shock-absorbing capacity when transporting loads on a cart equipped with a spring caster.
Some expensive ones are equipped with shock absorbers.
By increasing the shock-absorbing capacity, they not only reduce noise and abrasions when transporting loads but also reduce the load applied to start the cart.
Uses of Spring Casters
Spring casters are used on equipment such as transportation carts.
These carts are used to transport loads by applying intermittent and continuous force under human power.
It should be noted that these carts are not intended to carry people or animals.
Some types of spring casters are capable of handling very heavy loads, but they are designed to transport goods at speeds of only a few miles per hour.
Spring casters are often used in automobile factories.
Principle of Spring Casters
Spring casters use the elasticity of springs to cushion shocks and reduce vibrations by about half compared to ordinary non-spring casters.
Therefore, even precision parts can be transported without being damaged by vibration during transportation.
Furthermore, the life of the wheels, which are subjected to loads, is also significantly longer than that of general casters.
In addition, the resistance applied at the start of transportation, when the load is greatest, is also mitigated by the springs, enabling smooth transportation.
Coils are used for springs, and expensive ones are equipped with shock absorbers.
In addition to the spring, the material of the caster’s wheels also greatly affects the performance of spring casters.
Rubber wheels are often used for spring casters because of their higher elasticity and wear resistance.
Urethane wheels are harder than rubber wheels, which reduces the initial resistance, and they are more resistant to load and oil.
