<p>An actuation system for covering canvases (20) of an open top-body (12) is described, comprising a set of centerings (16) sliding with their own feet (17) on the side panel (14) of the top-body to support and open out/pack the coveringc anvas, a loop or a portion of rope (30) having two extremities in traction on one centering (18) of said set, called hauler centering, for moving it backwards and forwards on the side panel, and motor means for setting the rope loop in motion and moving the hauler centering. In order to simplify the actuation system, the motor means comprise a linear actuator mounted so that the linear movement it generates is converted into a movement of the rope.</p> |
