<p>Described herein is a sliding trolley for horizontal displacement of the tarpaulin for a lorry, comprising: a bracket (2) having a rectilinear portion (3) and a "goose-neck" portion (4) to which the tarpaulin is fixed; a single-wheeled trolley (6), carried by the rectilinear portion (3) of the bracket (2), which slides in a first longitudinal groove (7) made in a horizontal beam (1) belonging to the supporting frame of the tarpaulin (5); and a sliding block (8) (or other equivalent means) fixed to the end of the "goose-neck" portion (4) and suitable to slide in a second longitudinal groove (9) made in the supporting beam (1) above the first groove (7). The pin (14) of the single-wheeled trolley (6) slides in a vertical slot (10) made in the rectilinear portion (3) of the bracket (2), and a force is exerted on the pin (14) by an elastic element (15) which is fixed to or integral with the bracket (2). <IMAGE></p> |
