Serco Spring

Mechanical loading dock levelers have a system of coiled springs that enable the dock leveler to move up and down. When paw springs fail, the dock leveler can't be lowered into its proper non-operational position. If other springs fail, the dock leveler won’t move up at all, and no amount of force can be applied to push it up into its operational position. Springs are replaced more often than any other dock leveler parts because they are in use all the time.

Parts Brite carries a complete line of aftermarket springs for Serco mechanical loading dock levelers. We offer exceptional quality, durability, and customer support for every loading dock leveler spring we sell.
