A recycling control system for a dock leveler including a pivotally mounted deck. There is a powered lifting mechanism for raising the deck and a lip pivotally mounted to the deck for movement between pendant and extended positions. The control assembly includes a lip-position member couplable to the lip for movement therewith such that the position of the lip-position member is indicative of lip position. There is a switch couplable to the lifter and operable to a first condition wherein power is provided to the lifter and operable to a second condition wherein power is not provided to the lifter. There is an actuator disposed on the lip-position member for movement relative thereto between at least a first position where the actuator operates the switch to the first condition, and a second position where the switch can be operated to the second condition. The actuator is disposed to move between the first and second positions as the lip moves toward the pendant position.

DETAILED DESCRIPTION There is thus provided a recycling control system for a dockleveler including a pivotally mounted deck, a powered lifting mechanism for raising the deck, and a lip pivotally mounted to the deck for movement between pendant and extended positions, in which the control assembly includes a lip-position member couplable to the lip for movement therewith such that the position of the lip-position member is indicative of lip position, a switch couplable to the lifting means and operable to a first condition wherein power is provided to the lifting means, and operable to a second condition wherein power is not provided to the lifting means, and an actuator disposed on the lip-position member for movement relative thereto between at least a first position where the actuator operates the switch to the first condition, and a second position where the switch can be operated to the second condition, the actuator being disposed to move between the first and second positions as the lip moves toward the pendant position.
