Abstract

The embodiment of the invention discloses an auxiliary bracing connection device for carrying an arm support, relates to the technical field of construction machinery, and solves the technical problem in the existing technology that the service life of the arm support is short because the auxiliary bracing is easy to collide with the arm support. The auxiliary bracing connection device for carrying the arm support provided by the embodiment of the invention comprises the auxiliary bracing, a connecting seat body and a pulling plate, wherein one end of the auxiliary bracing is detachably connected with the connecting seat body, and the other end of the auxiliary bracing is connected with the pulling plate; and the connecting seat body is fixedly connected with the central position on the direction of an arm support base length of a boom. The embodiment is used for prolonging the service life and improving the use safety of the arm support.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a waist rope connection device for a load-carrying boom. Background technique [0002] In crawler cranes, the boom is connected by multi-section booms. The boom has two functions: one is to lift objects to a certain height and range; the other is to bear the load and make the load It is gradually transmitted to the whole machine and the ground through the lifting arm. It can be seen that the length of the boom is the main parameter that determines the operating height and range of the crawler crane. Therefore, in order to pursue greater lifting height and operating range, it is necessary to increase the length of the boom. [0003] The boom of a crawler crane is generally assembled on the ground by a multi-section (or called: multiple) boom, and the boom is raised to the working angle through its own luffing ability. The jib is a space truss arm structure, which ...
