Tow conveyor

Tow conveyor is conveyor that uses towline to provide power to wheeled carriers such as trucks, dollies, or carts that move along the floor. It is generally used when long distance and high frequency moves are required. Tow conveyor is used for fixed-path travel of carriers (each of which has variable path capabilities when disengaged from the towline).
Towline can be located either overhead, flush with the floor, or in the floor. Selector-pin or pusher-dog arrangements can be used to allow automatic switching (power or spur lines).[1]
