IMPROVED TROLLEY WHEEL

摘要

An improved trolley for use on a track. The improved trolley is of a sandwi ch construction having a wear resistant interior and a pair of metal end plates . The wear resistant material is preferably plastic or other material designed to avoid damaging a track along which the trolley rides. The end plates are preferably stainless steel and of a diameter greater than the diameter of the center wheel to prevent the trolley from becoming dislodged from a track. By providing a sandwich of long wearing and non brittle materials, the longevity of the trolley is increased and corrosion concerns associated with prior art devices are substantially alleviated.
