Abstract

The invention discloses a waist rope structure. The waist rope structure is characterized by comprising a waist rope and a connection device, wherein one end of the waist rope is connected with the end part of the connection device; the other end of the waist rope is connected with a pull plate; the connection device is arranged in an arm frame; and the connection device is connected with a web member at the top of the arm frame by a flexible connector. According to the waist rope structure, the stability of the waist rope is improved so that the whole body of the waist rope is not in contact with the arm frame, and the service life of the arm frame and the waist rope is prolonged.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a waist rope structure. Background technique [0002] In crawler cranes, the jib is connected by a multi-section jib, and the jib has two functions: one is to lift the item to make it have a certain height and amplitude; the other is to bear the load and make the load It is gradually transferred to the whole machine and the ground through the boom. It can be seen that the length of the boom is the main parameter that determines the working height and amplitude of the crawler crane. Therefore, in order to pursue a larger lifting height and working range, it is necessary to increase the length of the boom. [0003] The boom of the crawler crane is generally assembled on the ground by a multi-section (or: multiple) boom, and then the boom is lifted to the working angle through its own luffing ability. The boom is a space truss boom structure, which is mainly comp...
