ABSTRACT:
A racking apparatus10is provided for remotely inserting into and removing an industrial electric circuit breaker from a cell housing. The racking apparatus includes a housing having a base12and a frame14extending upwardly from the base. A Wheel structure20, 22, 24is coupled to the base to permit wheeled movement of the housing. A motor mount structure32is coupled to the frame for generally vertical movement toward and away from the base. An electric motor34is mounted to the motor mount structure. The motor has a shaft35and an adaptor structure36is operatively associated with the shaft. The adaptor structure is constructed and arranged to be coupled to a circuit breaker. Actuating structure40is associated with the motor mount structure to cause the generally vertical movement of the motor mount structure. A controller56is carried by the housing for controlling the motor and the actuating structure. A control station62is operatively associated with the controller to operate the controller at a location remote from the apparatus.
