Problems solved by technology

[0003] Using the auxiliary crane to install the jib, the user needs to bear the cost of the auxiliary crane and its driver, especially for long-distance transitions.
Moreover, the follow-up of auxiliary cranes leads to a large fleet size, which is not conducive to quick transition
In addition, when using the auxiliary crane to install the jib to the main jib, the required site area is relatively large, and the requirements for the hoisting site are relatively high.

Abstract

The invention discloses a self-installation method, a self-disassembly method and a self-disassembly system of a crane auxiliary arm. The self-installation method of the auxiliary arm of the crane includes controlling the main arm of the crane to hang the supporting structure on the transport flatbed and hoisting the auxiliary arm on the supporting structure; controlling the movement of the main arm to approach the auxiliary arm an arm; connecting the main arm and the secondary arm. The auxiliary arm self-installation method of the present invention completes the installation of the auxiliary arm by using the main arm of the crane itself, and no auxiliary crane is needed, thereby reducing the requirement on the installation site of the crane auxiliary arm. Further, the user saves the cost of the auxiliary crane and its driver without the need for the auxiliary crane, saves costs and can reduce the size of the crane fleet, which is conducive to quick transition.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a self-installation method, a self-disassembly method and a self-disassembly system of a jib of a crane. Background technique [0002] Large-tonnage telescopic boom cranes (with a lifting capacity of 200 tons and above) have a large self-weight. In order to meet the requirements of road transportation, the jib needs to be removed and transported independently on a transport flatbed when transferring. After arriving at the hoisting site, use the auxiliary crane to install the jib on the main jib. [0003] Using an auxiliary crane to install the jib, the user needs to bear the cost of the auxiliary crane and its driver, especially for long-distance transitions. Moreover, the follow-up of auxiliary cranes leads to a large convoy, which is not conducive to quick transitions. In addition, when using the auxiliary crane to install the jib to the main jib, the required site area i...
