ROOF VEHICLE II |
摘要 |
The invention relates to a truck (1) to be moved by a person comprising a frame with a bearing surface (2) and a supporting surface (3) extending substantially at a right angle to the bearing surface (2) and wheels connected to the frame, wherein the wheels are formed by rollers (6, 11, 13). The use of rollers instead of wheels has the advantage on the one hand that the surface pressure exerted on the roof by the truck is considerably lower than that of wheels, so that the load on the roof is smaller, while on the other the use of rollers has the advantage that the truck can also be moved easily over a corrugated roof, particularly when the direction of forward movement does not extend transversely of the corrugation direction.
