Abstract
A finishing system includes a frame that includes a bath station configured to communicate with an electrode. A hoist supported by the frame is movable into register with the bath station to establish electrical communication between the hoist and a current generated by a power source. The current drives deposition of a coating onto a load carried by the hoist. A drive assembly of the system is supported by the hoist and is operable to rotate a sprocket. The drive assembly includes a rotary conductor electrically coupled to the sprocket and configured to come into electrical communication with the frame. An electrically conductive lifting chain is operable through rotation of the sprocket to lower the load into the bath station. The frame communicates current from the power source to the rotary conductor, and the lifting chain communicates current from the rotary conductor to the load.
