Rite Hite Lip Assist Bar Replacement

Rite Hite, worn lip assist bar

In most Rite Hite dock levelers, a ring rolls in the curve of a lip keeper as someone walks across the deck of the dock leveler. This allows the lip assist bar attached to the ring to push the lip up.

Over time, the bar connecting the ring and the lip assist bar wears out, and the ring is unable to stay on the track of the lip keeper.This indirectly prevents the lip from raising when someone pulls the pull chain.

This tutorial demonstrates how to properly replace a worn lip assist bar in a Rite Hite dock leveler.
