<p>The loading platform (1) of a small to medium sized van or lorry is made of a multitude of transversally positioned segments (2) moving around drums (3) similar to the endless tracks or digger. The unit (2,3), driven manually, hydraulically, or electrically, is slightly pulled out for use and stops when its front touches a rubber stop (5) at the rear of the vehicle. Lateral deflectors (4) prevent dust and small particles from entering the system. A brush (16) at the rear cleans the segments (2) before returning.</p> |
