Abstract

This system may be used in the construction of self-propelled and lifting-transportation equipment. It reduces the number of operations necessary in the management of the mobile crane's support foot, which enhances its productivity. It consists of a platform (1), from the bottom side of which is fitted a double-action power cylinder (2), to the piston rods (3), on which - through hinged connections (4) - bearing beams (5) are placed. The bearing beams are fastened by a free-sliding motion in directing supports (6), connected to the platform by a vertical hinge (7). The directing supports are fitted to the angles of the platform, while the bearing beams in pairs are fastened through the hinged connections to each of the piston rods of the double-action power cylinder. To the idle edges of each of the bearing beams, a vertical lifting device (8) is fastened, the bottom end of which is formed in the shape of a leg. The lifting device is a screw and power cylinder.
