A method of operating a tilting carrier assembly includes operating a conveyor in a primary direction of travel and supporting a work piece from the conveyor by a pair of links. A pair of respective upper connection points of the links are laterally spaced transverse to the primary direction of travel and a pair of respective lower connection points of the links are also laterally spaced. The work piece is conveyed along the primary direction of travel relative to a work station, and the upper connection points are tilted so that a line therebetween forms a first angle relative to horizontal. In response, the lower connection points and the work piece are tilted to a second angle relative to horizontal, and the second angle is greater than the first angle.

A suspension conveying device according to the present invention includes screw shafts of two suspension line pulling-up/feeding mechanisms in a conveying traveling body 1. The screw shafts have low-speed drive regions, in which feed pitches for driven bodies are small, and high-speed drive regions, in which feed pitches for the driven bodies are large. The screw shafts are installed so that the low-speed drive regions and the high-speed drive regions are disposed mutually oppositely as viewed from the driven bodies when a conveyed object supporter is at one end of an elevation/lowering stroke, and the conveyed object supporter is tilted in a middle of the elevation/lowering stroke when the screw shafts are driven to undergo forward/reverse rotation at a fixed speed by a motor.

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.

A method of operating a finishing system includes providing a plurality of stations along a frame in a process direction, each station configured to receive and treat a load. A latent coating material is suspended in a liquid provided in an immersion station. A power supply generates electrical charge to the frame and the liquid. A hoist moves along the process direction and into register with the immersion station, the hoist including an electrically conductive lifting chain and an electrically conductive sprocket meshed with the lifting chain. The power supply and the sprocket are electrically communicated through the hoist. The load is connected to the lifting chain and immersed in the liquid. A path of conduction is established between the sprocket and the load solely through the lifting chain. Electrophoretic deposition of the coating material onto the load is driven through the electrical charge generated by the power supply.
