<p>The equipment (1) has connection units forming a deformable parallelogram, and including juxtaposed links (16) whose ends are mounted swivelling around vertical rotation axes on a tool portion (2) and an attachment portion (3). An offset operation unit (5) adjusts a lateral offset of the tool portion relative to the attachment portion by the links. One of the links consists of a telescopic element (15), which presents resting length provided with a lengthening and/or shortening clearance relative to the length. The element is associated with a hydraulic spring (17) along the length. The telescopic element is a fluid/hydraulic/pneumatic type jack.</p> |
