Abstract

The invention discloses a hydraulic supporting leg for a crane. The hydraulic supporting leg for the crane comprises a shell. A controller is fixedly connected to the left side of the top of the shell. A first hydraulic rod is fixedly connected to the right side of an inner cavity of the shell. A first supporting rod is arranged in the inner cavity of the shell in a penetrating mode. The right end of the first supporting rod is fixedly connected with the left end of the first hydraulic rod. First sliding blocks are fixedly connected to the right sides of the top and the bottom of the first supporting rod correspondingly. According to the hydraulic supporting leg for the crane, by using the first hydraulic rod and a second hydraulic rod, the supporting leg can stretch and retract flexibly, and the space is saved; meanwhile, by using a threaded rod, the second supporting rod can stretch out of an inner cavity of a base, the contact area between the base and the ground is enlarged, and the stability of a crane body is greatly improved; and the whole hydraulic supporting leg is reasonable in structure, easy to operate and high in practicability.
