<p>The equipment has a trolley (A) comprising vertical supporting uprights (2) whose heights are independently adjusted for adapting upright positions of the uprights on fixed planes (B1, B2) of a scale (B) of the trolley. The fixed planes are formed interdependent of opposite hooks (62, 64) with respect to upper cross-pieces (3) of the trolley to abut against inner faces, and associated with a spacer (E) interposed between the fixed planes to ensure locking of the fixed planes in a position drawn aside on the trolley and locking of the hooks on the cross-pieces.</p> |
