Abstract
An apparatus for operating a dock leveler including a lever adapted to be pivotably connected to the center plate for pivoting the center plate to the rearward position upon movement in a rearward direction to a first position. A lip extension apparatus is adapted to be connected to the lip plate and the base plate. The lip extension apparatus is operative for selectively pivoting the lip plate either toward the bridging position or to the stored position in response to forward movement of the lever at times when the center plate is in the rearward position. The lip extension apparatus includes an extension member and an extension stop member. A cocking apparatus is utilized to engage the extension member on the extension stop member for pivoting the lip plate toward the bridging position as the center plate pivots forwardly from the rearward position.
