摘要： A dock leveler support frame includes an upper frame member and a substantially vertical frame member connected thereto. The substantially vertical frame member includes both a structural member and a height-adjusting leg assembly. The leg assembly is adjustable via a drive member proximate the upper frame member. Rotating the drive member raises or lowers the upper frame member by altering the distance between the upper frame member and a foot at the lower end of the leg assembly. Ramp attachment points are also provided proximate the upper frame member. The support frame is installed by placing it in a pit with the upper frame member adjacent the curb, and adjusting the leg assembly to level the upper frame member to the curb. Once level, the back frame is secured to the dock, and the drive member may be secured to the upper frame member to prevent counter-rotation.
