A supporting leg which is mountable on a vehicle comprises an upper member (2) pivotable about an articulation (7), and a lower member (3) extendible from the upper member and adapted to be applied against the ground. On the upper leg member (2), there is provided a hydraulic cylinder (13) comprising a cylinder (14) and a piston rod (15) connected to one end of a flexible traction means (17), whose opposite end is connected to a fixed point of attachment (18). The traction means (17) is passed round a runner (19), and shortening of the hydraulic cylinder forces the supporting leg to pivot about the articulation (7) from an operative, swung-down position to an inoperative, swung-up position. |
