Abstract
A plastic conveyor trolley structure having plastic bearings and made of a super tough plastic material, comprises a pair of complementary arms each supporting a wheel for rotation on roller bearings held in a fixed inner race forming an integral part of a stub axle on which the trolley wheel is rotatable. The trolley is readily movable on the flanges of an I-beam monorail. A pendant member secured to and between the lower ends of the trolley arms is engaged by the conveyor drive chain to move the trolley along on the monorail. Metal screws are used to hold the depending member to the arms and to secure the stub axle for the trolley wheel to its supporting arm.
