Abstract

The invention discloses a mobile crane with four-corner support, which relates to the technical field of mechanical engineering; a beam, a longitudinal beam, a lifting trolley, a hook, a connecting device, a lifting arm, a car body and four automobiles or tire-type cranes; The beam and the longitudinal beam are connected to form an I-shaped or square frame, the lifting trolley is set on the beam, the boom is set on the car body of the automobile or tire crane, and the connecting device is set on the beam and the longitudinal beam. On the four corners and booms that make up the frame, the booms of four trucks or tire-type cranes are respectively installed on the four corners of the frame formed by beams and longitudinal beams through connecting devices; Above; the lifting weight of the present invention is large, the lifting range can exceed a crane diameter range, and it is easier to move than ordinary bridge cranes.

Description

Technical field [0001] The invention relates to a four-corner supporting mobile crane, which belongs to the technical field of engineering machinery. Background technique [0002] Existing mobile cranes generally work alone, so the lifting weight is small and the lifting range is within a certain radius. The ordinary bridge crane is not convenient to move. Summary of the invention [0003] In view of the above problems, the technical problem to be solved by the present invention is to provide a mobile crane with a combined structure. [0004] The present invention includes a beam, a longitudinal beam, a crane trolley, a hook, a connecting device, a boom, a car body, and four cars or tire cranes; the beam and the longitudinal beam are connected to form an I-shaped or lip-shaped frame for lifting The trolley is set on the cross beam, the boom is set on the body of a car or tire crane, the connecting device is set on the four corners of the frame composed of the cross beam and the lo...
