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 assembly 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 frame configured to be mounted to a loading dock;

a deck assembly pivotally mounted to the frame; and

means for counter balancing the deck assembly mounted at one end to the deck assembly and mounted to the frame at the other end, the counter balancing means located substantially above the top surface of the deck assembly.

2. The dock leveler of claim 1, wherein the counter balancing means runs substantially parallel along a side of the deck assembly.

3. The dock leveler of claim 1, further comprising a curb running along a length associated with the deck assembly.

4. The dock leveler of claim 3, wherein the curb provides a housing for the counter balancing means.

5. The dock leveler of claim 3, wherein an end of the curb and the frame define a gap that varies in length with respect to the position of the deck assembly as it pivots on the frame and further comprising means for covering configured to cover the gap.
