Abstract
A dock leveler for providing a bridge into the rear end of a truck trailer over which a fork vehicle can travel in loading the truck trailer. The dock leveler includes a ramp with a rear section and an extendible forward section. The forward section telescopically extends from and retracts into the rear section under power from a hydraulic cylinder. The forward section can be locked in place to prevent retraction of said forward section relative to said rear section under the traction developed by the drive wheels of a fork vehicle as the fork vehicle travels over the dock leveler. Various structures for indicating the amount of overlap of the dock leveler on the truck trailer are also provided.
