Abstract

See full text

The handling properties of two-wheeled trolleys may be materially improved by arranging for the freely rotatable wheels (1, 2) to be able to move to a certain extent relative to the frame or load-receiving container portions (3, 4, 5) of the trolley in a direction parallel to the direction of travel of the trolley. This can be achieved by mounting the trolley wheels (1, 2) so that they, and the axles (32) on which they are mounted for free rotation, can, preferably independently, swivel about a horizontal axis displaced from (and lower than) the level at which the wheels are mounted on their respective axles. The wheels are preferably set at a high positive camber angle. Letting the wheels swivel materially improves handling on rough terrain. The trolley is preferably foldable to save space when being transported or stored.
