A mechanism for loading and unloading a container onto a tray attached or attachable to a track or trailer vehicle. The mechanism includes a transverse assembly at each end of the tray, each assembly incorporating a centrally mounted telescoping boom, a lower part of which incorporates an extension to which opposed hydraulic rams are linked. The hydraulic rams control the swinging movement of the boom when one retracts and the other extends. |
