Industrial Drawbar Spring

About Industrial Drawbar Spring

Drawbar springs are assemblies in which the spring will compress as the drawbar arms extend under an applied load and they are often capable of withstanding loads far in excess of the compression spring closing force and should be considered in applications where overload protection is required.

Spartan Spring offers the drawbar spring has a hard stop at the compression spring solid height which makes it the optimal choice in applications where overload protection is necessary.

Drawbar spring is a commons examples of the extensions springs types that have space between the spring coil. This allows it to expand or contract as per the springs that want to handle the loads. What differentiates a drawbars springs from other extensions springs is that in a drawbars spring, the loads are applied at the end of long steel loops passing through the center of the spring and are hooked around to the other end of the springs.
Thus, they function well in any potential overload situation. The drawbar springs were made as a solution for the situations where extensions springs hook stress concentrations limit the load-carrying potentials.
