<p>Runner for tarpaulins for the box bodies of trucks or the like, formed by a carriage (1) that has three wheels (3.1, 3.2, 3.3), in a triangular arrangement, and a guide (2) that defines two rails (2.1, 2.2) that face each other vertically, two of the wheels (3.1, 3.2) of the carriage (1) resting on one of the rails (2.1) of the guide (2), whilst the third wheel (3.3) is facing, with clearance with respect to the other rail (2.2), such that movement is produced by rotating the wheels (3.1, 3.2) on the rail (2.1), and if there is any tilt of the carriage (1) the wheel (3.3) enters into contact with the rail (2.2), preventing blocking and disengagement from the rails.</p> |
