Articulating Trolley utilizes a hanger system that allows for 5 degrees of movement reducing stress on the trolley wheels increasing the life of the trolley and rail while improving the overall smoothness of the movement. These trolleys utilize a heavy structural load bar that rides under rail on trolley yokes allowing the trolley to swivel and articulate freely. When articulating trolleys are motor-driven, the motor and gear-reduction assembly are built in the configuration of a modified yoke, in which the driving wheels are also mounted, thus forming a compact integrated unit.
