Abstract
A racking device performs a circuit breaker racking operation. The racking device includes a base with wheels and a brake to facilitate moving the racking device and positioning it with respect to a switchgear cabinet. An elongated tubular member extends substantially vertically from the base. A self-contained counter-balanced power module includes an enclosure having a pair of opposing openings for receiving the elongated tubular member, and a counterweight system for counter-balancing the power module. An actuator including a motor, a ball spline and a torque member moves a linkage assembly having an end effector with a negator spring that positively engages the circuit breaker. A switch module actuates the actuator from a remote location in order to move the linkage assembly and thus the circuit breaker to perform the racking operation from the remote location. Complicated field programming of the power module is not required.
