The scissors lift mechanism comprises first and second scissors arms mounted on a base frame, one of the arms pinned to the base for pivotal movement and the other of the arms is free to move relative to said base. Hydraulics are employed to raise scissors lift. The scissors lift mechanism further comprises an upper frame having a generally horizontal deck portion. Retractable pins are used to couple said scissors lift mechanism to the pit in the fully raised position. The a dock leveler deck assembly is pivotally mounted to the generally horizontal deck portion of the scissor lift mechanism, and hydraulics coupled to the scissors lift mechanism raises the deck assembly. The scissors lift mechanism includes lip keepers that in one position retain the leveler lip in the pendent position and in a second position support the outboard end of the leveler deck.
