How to install a crane in a steel structure workshop

Crane is a hoisting machine installed in a steel structure workshop for lifting various heavy objects, which can greatly reduce the labor intensity of workers and is an indispensable equipment in industrial production. There are many types of cranes to choose from in the steel structure workshop, such as bridge cranes, gantry cranes, semi-gantry cranes, jib cranes, etc. Users can choose the appropriate type according to the site conditions.

Both ends of the bridge crane sit on tall concrete columns or metal supports, shaped like a bridge. The bridge of the bridge crane runs longitudinally along the track laid on the elevated on both sides, which can make full use of the space under the bridge to lift materials without being hindered by ground equipment. It is the most widely used and the largest number of hoisting machinery.

Gantry crane is a variant of bridge crane, also known as gantry crane. The metal structure of the gantry crane is like a gantry frame. Two feet are installed under the main beam, which can walk directly on the track on the ground. The two ends of the main beam can have outrigger cantilevers. If an overhead crane cannot be installed in the workshop, a gantry crane can be considered.

Semi-gantry crane is an intermediate type of bridge crane and gantry crane. One end runs on the crane beam of the factory building, and the other end runs on the ground track, which can use the site more efficiently.

The cantilever crane is a small-scale operation hoisting machine, suitable for lifting heavy objects in a fixed working area, and the lifting tonnage is generally small.

Allowable deviation of crane beam installation in steel structure workshop (mm):

Mid-span verticality of beam: h/500;

Lateral bending sagittal height: l/1500 and should not be greater than 10.0;

Vertical upper arch sag: 10.0

Center displacement of supports at both ends:

1. When installed on a steel column, the offset to the center of the corbel: 5.0;

2. When installed on a concrete column, the offset of the positioning axis: 5.0;

Offset between the center of the stiffening plate of the crane beam support and the column bearing stiffening plate: t/2;

Bridge cranes are mostly used in steel structure workshops. Users can also choose other types of cranes according to their own conditions, or use a combination of various types of cranes. Improve the production efficiency of enterprises.
