Extendible four wheeled trolley - has single beam chassis on which are mounted two transverse members with free and steering wheels

摘要

The trolley is for moving and lifting iron rods etc. to be handled in a store. There is a single spar chassis (3), fixed or extendable. The two ends of this have a transverse member (11), at the ends of which are wheels (5, 7, 8) steering and free swivelling to give free trolley movement. Mounts (13) are fixed to the transverse members and are telescopic. The four transverse ends can carry three freely swivelling wheels and one steering one. A drawbar, pivoted and movable, gives easy handling. A stop blocks the movement of the steering wheel to give easy handling without a drawbar.
