An improved lip extension and control assembly is provided for use in a dock leveler. The dock leveler (16) has a ramp pivotally connected to a stationary frame in a conventional manner for pivoting between a pendant, stored position and an extended preparatory position. The lip (38) is hingedly connected to the front edge of the ramp (16). The assembly has an extending means operatively connected to the lip for extending the lip in response to the rotation of the ramp to the extended position. A pivot controlling means operatively connected to the lip controls the rotation of the lip in a programmed manner such that upon walking the deck down, the descent of the lip progressively increases from the extended position to the pendant position. |
