Crane boom base of light-weight hoisting transport vehicle

Abstract

The invention relates to a cargo boom base of a light-weight hoisting transport vehicle. The cargo boom base comprises a base disc (1), a left side plate (2), a right side plate (3), a front connecting plate (4), a rear connecting plate (5) and a variable-amplitude oil cylinder hinge seat (6), wherein a winch mounting plate (7) is arranged between the left side plate (2) and the right side plate (3), the two sides of the winch mounting plate (7) are welded on the rear sides of the left side plate (2) and the right side plate (3), the left side plate (2) and the right side plate (3) are each composed of an inner side plate (8) and an outer side plate (9), the peripheries of the outer side plates (9) are bent towards the inner side plates (8), the edge parts are welded with the peripheries of the inner side plates (8), and the lower parts of the inner side plates (8) and the outer side plates (9) are welded with the base disc (1). The cargo boom base has the advantages that the strengthis guaranteed, the weight is light, the open welding phenomenon is not likely to happen, and safety is good; and due to the fact that welding stress is overcome, the open welding phenomenon is avoided, the lifting capacity can be improved, and use is safer and more reliable.

Description

technical field [0001] The invention relates to lifting equipment, in particular to a lifting arm base of a light lifting transport vehicle. Background technique [0002] Lifting and transporting vehicles are different from ordinary cranes. They have the function of lifting and transporting goods at the same time. In order to improve the transport function, the crane part must not be too heavy while ensuring reliable lifting capacity. The two column side plates on the jib base of the existing lifting transport vehicle are respectively cut and processed from thick steel plates. Although the strength is guaranteed, the weight is relatively large, and the welding effect with the base disc is not good enough, so it is not easy To overcome the welding stress, it is easy to open the welding phenomenon, which has certain potential safety hazards. Contents of the invention [0003] The object of the present invention is to provide a jib base of a light-duty lifting transport vehi...
