Abstract
A gravity conveyor has a work supporting trolley provided with multiple wheels of different diameters fixed to a shaft that operates a retarder for applying a retarding torque to the wheels proportional to their angular velocity. The conveyor track consists of multiple, laterally spaced, resiliently flexible rails on which selective wheels of the trolley are adapted to roll. The axial spacing of the tracks and wheels simplifies the location of the two centers of gravity of the loaded and unloaded trolley.
