<p>The present invention relates to a simplified system for attaching the wheel (4) of a wheelbarrow, in which the axle (3) is also the means for joining the rolling system to the frame (1) and to the front strengthening element (7) of the load container. The wheelbarrow is improved or simplified by using a step screw, usually with a diameter of five sixteenths of an inch or eight millimetres, as the axle (3) of the rolling system, said screw passing through the orifices (2) made in the body of the frame at the vertical midpoint thereof, the system being closed with a single nut (8). The axle may also pass through the perforations made in the lower extremities of the strengthening element of the front part of the load container. With this system, use of the wheelbarrow is substantially as efficient as in traditional systems, with the benefit that the assembly parts and production costs are reduced, and the assembly procedures and replacement of the rolling system are facilitated.</p> |
