Abstract
An adjustable leg assembly for a loading dock ramp member having an elongate, adjustable housing with incremental slots, a hydraulic system having a hydraulic pump with a cylinder fully contained within the housing and a handle for operation of the hydraulic system. The leg assembly also includes a lock bracket for insertion into the slots to contact the cylinder for even distribution of compression loads. A user pumps the handle to actuate the hydraulic system and thereby adjust the loading dock to the desired height.
