<p>Hydraulic stabilizer legs (2) for trucks with a crane are disposed on support beams (1) and point downwards in the operational position. During change-over to the drive position the stabilizer legs are retracted in the hydraulic cylinders, are swiveled in an upwards pointing direction, and the support beams are retracted. In known constructions the swiveling is caused by e.g. a rack-and-pinion system, which leaves a downwards-pointing rack, even though the stabilizer leg itself points upwards. According to the invention this disadvantage may be avoided simultaneously with a protected mounting of the mechanism, in that the conversion between a linear movement of a hydraulic piston (6) and swiveling of the stabilizer leg (2) is obtained by the use of rollers (21-27) in a circular track (19) that continues a straight track (18) in the housing of the converter.</p> |
