Abstract

The invention belongs to the technical field of hoisting, and specifically relates to a crane, which includes a base and a main girder. The main girder is provided with a first slide rail and a second slide rail. The trolley, the second sliding rail is equipped with a second walking trolley for lifting workpieces, and the main beam is also equipped with an arc transition track for connecting the first slide rail and the second slide rail, and the arc transition track on the main beam is There is a rotating auxiliary component at the position. When in use, the first traveling trolley and the second traveling trolley can lift materials separately, or with the assistance of the rotating auxiliary component, the first traveling trolley and the second traveling trolley can travel to Work together on the same slide rail to realize vertical lifting of slender parts.

Description

Technical field[0001]The present invention belongs to the field of lifting technology, and more particularly to a crane.Background technique[0002]At present, the crane is widely used in aviation, aerospace, nuclear power and other fields. It can perform vertical improvement in the set range, horizontally handling, with the continuous expansion of the infrastructure project, the use of cranes in engineering construction is more and more extensive, in order to improve lifting Efficiency, the prior art authorized notice number is a patent document of CN100460305C discloses a rail-type double-cauter gantry type container crane, and has specifically disclosed two lifting trains on the main beam, and the double car is provided with respective rails, respectively. And each of the respective lifting drive mechanisms, trolley operation mechanisms, rising wire rope wound systems, and hanging systems are connected. However, when the elongate member is lifted, it is necessary to hook both ends ...
