The invention relates to a levelling-stabilising device for objects supported on legs, objects such as tables, ladders, scaffolding and generally objects that have legs as supporting elements, characterised in that it consists of at least two vertical supports (1,1') on the lower end of each of which is arranged a hydraulic chamber (2,2') containing a piston (3, 3') that forms the element for support on the ground (4), the two hydraulic chambers (2,2') being connected by means of a hydraulic circuit (5) provided with a key (7) for interrupting same, such that when the key (7) is in an opening position, the pistons (3,3') can move together in the vertical direction, and when the key is closed, the pistons are locked in a working position. |
