Embodiment Construction

[0019] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0020] As shown in Figure 2(a) and Figure 2(b), the embodiment of the present invention provides a main luffing mast for a crawler crane, the main luffing mast is set on the crawler crane platform, wherein the main luffing The mast is composed of two parts, the upper module 1 and the lower module 2 , and the upper module 1 and the lower module 2 are connected together by a joint 3 . Preferably, the joints are connected by pins. As shown in Figure 3(a) and Figure 3(b), the joint 3 is disassembled during transportation, the upper module is transported together with the platform, and the lower module 2 is transported together with the winch mechanism, which can easily meet the transportation requirements and save transportation cost.

Abstract

The embodiment of the invention discloses a main amplitude mast of a crawler crane and belongs to the technical field of the crawler crane. The main amplitude mast of the crawler crane is arranged on a crawler crane platform. The main amplitude mast consists of an upper part module (1) and a lower part module (2). The upper part module (1) and the lower part module are connected together through a joint (3). The invention also discloses the crane. The crane comprises the main amplitude mast provided by the invention. According to the main amplitude mast of the crawler crane, through dividing the main amplitude mast into the two modules connected through the joint, not only be the length requirement of transportation met but also the optimal design requirement of the main amplitude mast can be met.

Description

technical field [0001] The invention relates to the technical field of crawler cranes, in particular to a main luffing mast of a crawler crane and a crane including the mast. Background technique [0002] At present, the main luffing mast 11 used by crawler cranes is arranged on crawler crane platforms 12, see figure 1 , is an important part of the crane. For large-tonnage crawler cranes, due to the jib lifting requirements and hoisting moment requirements, the length and weight of the main luffing mast will increase significantly, especially the length, which usually exceeds the length requirements in the transportation requirements. If the length of the main luffing mast needs to be reduced in order to meet the transportation requirements, then it often cannot meet the lifting requirements of the long main boom, nor can it achieve the optimal stress state. Contents of the invention [0003] In order to solve the problems that the main luffing mast in the prior art cann...
