Abstract

A traction wheel turn for a power and free conveyor employs a single rotary unit to effect a complete, 180.degree. reversal of the course of the conveyor. A circular track component forms a part of the free track at the inside of the turn and is carried by the traction wheel and rotates therewith. The inside wheels of the free trollies transfer from a standard, straight track section to the circular component at the turn, are carried thereby through the turn, and are delivered to the next stationary track section at the end of the turn. The horizontal space occupied by the turn is therefore, no greater than the diameter of the traction wheel.
