The Wildeck LiftLok safety system prevents lift operation by untrained or unauthorized personnel. A basic key switch or a 10-key push-button digital keypad can be added to any Wildeck mechanical or hydraulically-operated vertical reciprocating conveyor (VRC). Two keys are provided with the basic LiftLok keyed system while authorized lift operators can enter a unique 4-digit user passcode or swipe their pre-programmed proximity credentials tag (key fob) on the LiftLok digital keypad to enable lift operation.
