Problems solved by technology

Depend on image 3 From the top view of the boom structure, it can be seen that the upper and lower surfaces of the boom structure are arranged with different numbers of horizontal and vertical crossbars. During the nesting and assembly process of the boom, when the Figure 4 In the position shown, due to the interference of the crossbar on the upper surface of the boom, the nesting process cannot continue. At this time, only the Figure 4 Remove the hanging point, select another lifting point or use other auxiliary means for nesting assembly, the nesting assembly efficiency is low, and during the replacement of the hanging point or the embedding pro

Abstract

The invention relates to a jib structure, a jib system and a crane. The jib structure comprises a jib body which comprises a plurality of side surfaces and two end surfaces, wherein all the side surfaces are welded by a plurality of cross bars, and a roller device is arranged on the cross bar in one side surface. According to the jib structure, the roller device is arranged on the jib body, the jib structure with the small cross section is nested into the jib structure with the large cross section by the roller device, the jib sections with the different cross sections can be nested and assembled, and the quantity of vehicles for transporting the jib structure can be reduced.
