The small, compact, collapsible three-wheeled truck has a foldable ramp (12) which rests flat on the ground while the rear wheels (3) are in slightly raised position, so as to prevent movement of the truck while the flat tyre is being driven onto it. As the ramp (12) pivots upwardly into retaining position behind the tyre, the rear wheels (3) are lowered into ground contacting position. Simultaneously, an extension (15) attached to the ramp causes a retaining member near the front of the truck (10) to pivot upwardly out of the way of the approaching tyre into the front retaining position. The tyre after mounting, rests in a cradle (11) and is prevented from moving forwardly or rearwardly with respect to the truck. <IMAGE> |
