A conveyor trolley assembly comprises a molded plastic one-piece trolley body having a yoke defined by a base portion and a pair of arms extending symmetrically therefrom to a pair of transversely spaced extremities. The yoke and pair of arms are formed as a beam having inner and outer flanges connected by a pair of hubs adjacent to the arm extremities and by a web joined to the flanges and hubs. A pair of trolley wheels is mounted on the pair of hubs. An integrally formed load supporting stem extends from the base portion of the yoke oppositely to and intermediate the pair of arms. The stem has a pair of transversely spaced shoulders, and a pair of sides projecting from the shoulders are adapted to extend through a conveyor chain center link mounted on the stem in abutment with the shoulders. An molded plastic attachment bracket for retaining the center link on the stem and attaching a load to the trolley has a pair of stem engaging portions provided with projections fitting in recesses in the sides of the stem and transmitting load supporting forces thereto. A transverse bolt extending through the bracket and stem maintains the projections in engagement with the recesses. The attachment bracket may be formed by a pair of half-brackets, or by a one-piece bracket which can be snapped into engagement with the stem.
