Mobile Machine With Supporting Legs

Mobile work machine having a chassis (10), having at least two support legs (20) disposed laterally on the chassis, in pairs, which legs have an extension tube (28) articulated onto a location on the chassis, and a foot part (24) that can be extended downward, in telescope-like manner, and supported on the ground, preferably by hydraulic means (44), whereby the extension tube (28) is configured in the manner of a two-arm lever, forming a lower lever arm (40), with reference to the pivot axis (34), which contains the foot part (24), and an upper lever arm (42), wherein the upper lever arm (42) engages into a guide link (54) in the region of its free end (slide shoe 52), the one end of which link forms an end stop (56).
