Description

Technical Field

[0001] The invention relates to the technical field of crane trolley equipment, and in particular to a crane trolley with an all-round adjustable lifting hanger. Background Art

[0002] The crane trolley is an assembly that moves the suspended load. It is usually installed on the crane and is used to complete the handling, hanging, loading and unloading of materials. The main function of the crane trolley is to move on the track to achieve the lifting and transportation of heavy objects. With the rapid development of the transportation and lifting industry, rail-mounted cranes are widely used in large cranes and port equipment. As an important working mechanism in the crane, the trolley directly affects the working efficiency and loading and unloading capacity of the crane equipment.

[0003] At present, in the existing rail-mounted cranes, most of their lifting trolleys are set up with double drums and equipped with a set of electro-hydraulic push rods to achieve the lifting and lowering of the hoisted goods and the deflection of limited positions. However, as the requirements for lifting and hoisting operations become increasingly complex, and the transportation and loading and unloading positions of goods are also required to be more precise, the lifting trolleys of traditional rail-mounted cranes are limited by their structures and can generally only lift and lower the hoisted goods and deflect them in limited positions. They cannot achieve displacement perpendicular to the direction of movement of the trolley track, tilting of the sling, deflection of the upper and lower angles, etc., resulting in the inability to meet the lifting requirements.

[0004] Therefore, how to provide a crane with a fully adjustable lifting hanger, which can fully adjust the position of the lifted cargo and achieve flexible adjustment of the hanger positioning, has become a technical problem that needs to be urgently solved by technical personnel in this field.

Since the slewing hanger 9 can perform a slewing action, the slewing hanger 9 can be used to adjust the plane rotation position of the hoisted cargo. As described above, the technical solution provided by the present invention, compared with the prior art, can adjust the position of the hoisted cargo in all directions and realize flexible adjustment of the hanger positioning.

[0092] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
