ARTICULATED VEHICLE WITH HEIGHT ADJUSTABLE LOAD RECEIVING BODY

摘要

Articulated vehicle (10) includes prime mover (11) with drive wheels (23) and trailer (12) and is intended to collect and transport shopping trolleys. Prime mover (11) is connected to trailer (12) by means of pivot couplings to permit relative pivoting movement between prime mover (11) and trailer (12) about a vertical axis and a generally horizontal transverse axis. A resilient means (such as a spring or an air-bag) extends between prime mover (11) and trailer (12) and urges prime mover (11) and trailer (12) to be generally horizontally aligned. Trailer (12) includes U-shaped chassis (13) and a vertically movable load receiving tray. Hydraulic cylinders arranged in series raise the load receiving tray to a transport position or to lower the tray so that shopping trolleys may be loaded or unloaded.
