Abstract

The invention discloses a crane with a self-dismounting over-lifting device and a dismounting method of the over-lifting device. The crane comprises a front positioning device and a rear positioning device which are respectively arranged on the front and rear of a chassis, wherein the front positioning device comprises a lifting support and an over-lifting positioning bracket arranged on the two sides of the lifting support, and the positioning bracket comprises an over-lifting positioning pin shaft; the rear positioning device comprises a supporting base and a group of supporting frames, and the supporting base is provided with a positioning hole or a guiding groove; one ends of the group of supporting frames are respectively fixedly connected with the over-lifting device, and the other ends of the group of supporting frames are provided with idler wheels; head ends of a first over-lifting arm assembly and a second over-lifting arm assembly are respectively connected with a basic arm of a lifting arm through the pin shaft. The crane and the dismounting method of the over-lifting device provided by the invention have the advantages that a device carried by the crane is utilized for rapidly finishing positioning and dismounting the basic arm of the lifting arm, the dismounting over-lifting time is greatly shortened, the inputs of manpower and material resources are reduced, meanwhile, the dismounting over-lifting required operation area is reduced, and the crane has a strong field adaptability.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a crane with a self-detachable super-lifting device and a method for assembling and disassembling the super-lifting device. Background technique [0002] With the development of large-scale and multi-functional wheeled cranes, some auxiliary devices aimed at improving their lifting performance have been widely used, which has led to the increasing weight of the crane itself, far exceeding the national total weight of the crane. and bridge charges are strictly limited. In order to meet this transportation requirement, large wheeled cranes usually only carry the most basic operating devices in the driving state, and other devices need to be dismantled and transported separately. In order to ensure the characteristics of quick transfer, quick and easy assembly, and quick operation of the wheeled crane, the installation and removal of these auxiliary devices must be si...
