A trolley assembly comprises a frame incorporating at least one tire encompassing a wheel bearing and a bumper comprising a first portion made of a comparably incompressible material and a second portion made of a comparably compressible material. The bumper is mounted on the frame such that the bumper moves upon impact with an object, compressing the compressible material. For example, the incompressible material may be a polyamide and the compressible material may be a neoprene extrusion.
