Abstract

A dock leveler for bridging the gap between a loading dock and the bed of a vehicle parked at the loading dock. The dock leveler is configured for installation on the top of the dock and is designed to rotate from a vertically-stored raised position to at least one lowered, operative position. In some embodiments, the dock leveler can be lowered either for normal operation so that the deck rests on the bed of the vehicle or it can be lowered to accommodate an end-loading condition.

Claims

1. A dock leveler, comprising:

a base assembly configured to be installed on a substantially level top surface of a dock, wherein the base assembly comprises a ramp assembly having an inclined ramp plate and a pivot shaft engagement mechanism which is either integral with the ramp plate or is a separate component attached to the ramp assembly; and

,

a vertically-storing deck assembly being pivotally attached to the base assembly, wherein the deck assembly comprises a pivot shaft, and the deck assembly has a forward end and a rear end, the forward end being farther from the base assembly than the rear end, and the pivot shaft being attached at the rear end of the deck assembly.

2. The dock leveler according to claim 1, wherein the pivot shaft engagement mechanism comprises a channel portion configured to receive the pivot shaft.

3. The dock leveler according to claim 1, further comprising at least a first spring anchor assembly mounted on a first end of the pivot shaft.

4. The dock leveler according to claim 1, wherein the deck assembly further comprises an extendible lip pivotally attached to the deck assembly.

5. The dock leveler according to claim 1, wherein the inclined ramp plate provides a transition over the pivot shaft.
