ABSTRACT:
A dock leveler having a frame adapted to be fixedly mounted at a dock with a deck, pivotedly mounted to the frame at one end thereof, and having a pivotable lip at the other end. A spring is mounted to the deck and the frame and supports the deck. An electric actuator is coupled to the deck and the frame and moves the deck from a generally horizontal stored position into an operative position. A control circuit is employed for controlling operation of the electrical actuator. The actuator carries a limit switch which is responsive to movement so that power is terminated to the actuator when the deck reaches either a stored or operative position.
