Supporting leg

The device has a joint mechanism for pivoting the support between a transport position and a working position. A bearing journal of a horizontal transverse crane element (1) and an eye bearing for a pressure cylinder (3) form a pivot axis (A) for the support relative to the transverse crane element. A protruding plate is fixed on the front of the bearing journal. Two fixed clamp brackets are fixed to a casing of the hydraulic cylinder (5) and a fixed guide rod (11) inserted between them carries a sliding element (12). An axially guided guide rod is joined to the sliding element at one end with the other end free.
