Problems solved by technology

The specific method is to change the existing rear counterweight into a mobile counterweight. The movable range of this counterweight is small, and the improvement of lifting performance is not obvious.
Or change the superlift counterweight into a mobile counterweight. This kind of counterweight has a complicated structure and needs to be realized by adding an auxiliary support frame under the superlift mast, which is costly

Abstract

The invention discloses a tracked crane. The tracked crane comprises a turntable, and further comprises a turntable extension mechanism arranged at the tail end of the turntable, a support mechanism arranged at the tail end of the turntable extension mechanism, a track beam and a balancer support mechanism mounted on the track beam in a sliding manner, wherein one end of the track beam is connected with the support mechanism, and the other end of the track beam is connected with the turntable. The tracked crane provided by the invention has a wide balancer moving range, can effectively increase the hoisting performance, and is simple in structure.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a crawler crane. Background technique [0002] Crawler crane is a kind of boom rotating crane that uses crawler to walk. The crawler crane has the characteristics of large crawler ground area, good passability, strong adaptability and load-carrying walking. Crawler cranes can perform various operations such as digging, ramming and piling, and are the main construction machinery for hoisting operations on construction sites. [0003] The counterweight is an important part of the crawler crane to ensure the stability of the whole vehicle. Generally speaking, the further back the counterweight is set, the more it helps to increase the lifting moment of the crane. However, the rear counterweight will increase the backward tilting tendency of the whole machine, causing the problem of unstable center of the crawler crane. In order to solve this technical problem, prior art also...
