SELF-PROPELLED AND ARTICULATED VEHICLE WITH TELESCOPIC JACKS TO CARRY PIPEWORK INSPECTION |
摘要 |
<p>The self-propelled vehicle intended to move in an essentially circular space has a central load-bearing structure made of frames placed in a longitudinal direction. Sets of jacks are arranged in transverse planes perpendicular to this direction and bear at their end a set of driving elements. Each jack rod end has hollow rods of different diameters that are disposed concentrically about a longitudinal axis of the jack. These hollow rods are connected to one another and to the jack by a member for rotating the jack together with the hollow rods about the longitudinal axis.</p> |
