Abstract
An apparatus for operating a dock leveler including a linkage pivotably connected at a first end to the base plate. The second end of the linkage is adapted to selectively engage the center plate at times when the center plate is pivoted from its forward position toward its rearward position. Preferably, the second end of the linkage includes a roller apparatus to roll along the underside of the center plate during the pivoting operation. A lever tube is rigidly connected to the second end of the linkage and is adapted to hold an operating lever. The operating lever is in a substantially vertical orientation at times when the center plate is in the stored and bridging positions. When the center plate is in the retracted position, the operating lever is adapted to be in a position that is easily reachable by the operator with only a minimal degree of bending required.
