20 Ton Single Girder Bridge Crane Sent To Saudi Arabia

20 ton single girder bridge crane sent to Saudi Arabia

Product name: Single girder bridge crane

Product quantity: 1 set

Product parameters: 20 ton - 10 m

In early February, a customer from Saudi Arabia contacted us and told us the requirements for the bridge crane they needed: lifting weight, lifting height, lifting items, etc. According to the customer's needs, we customized a design for them - LD single-girder bridge type Crane, in order to protect customer privacy, will not describe too much here.

LD model single girder overhead crane

LD model single beam bridge crane is composed of the main girder, end girder, electric wire rope hoist and operating mechanism welded by steel plate and I-beam, the electric wire rope hoist runs along the lower flange of the main beam I-beam to complete the lifting and transportation of the items. It has the characteristics of light structure, convenient installation and maintenance, etc. It is widely used in various factories, storage warehouses, material yards, glass factories, power plants and other occasions to lift goods . The Working Class is A3-A4.

The acceptance criteria for the traveling beam of a 20 ton bridge crane are mainly as follows:

1. The coordination between the entire crane and the factory building, as well as the coordination between the trolley and the bridge frame, must be appropriate. The mutual cooperation between the trolley and the bridge mainly lies in: the trolley gauge (the horizontal distance between the wheel center planes) and the trolley gauge on the bridge should be the same; secondly, the position of the buffer on the trolley and the stopper on the bridge should match well. , the striker on the trolley and the travel limit switch on the bridge must match properly. The layout of the trolley should be compact and the height should be small. Correspondingly, the height of the crane can be reduced, thereby reducing the height of the factory building.

2. The layout of the mechanism on the trolley and the coordination requirements between the parts in the same mechanism are appropriate. The distance between the lifting mechanism and the trolley operating mechanism should not be too small, otherwise maintenance will be inconvenient or the trolley frame will be difficult to design; but it should not be too large, otherwise the trolley will not be compact.

3. The wheel pressure distribution of the trolley wheels must be uniform. And it is required to obtain the minimum size of wheels, axles and bearing boxes, and to ensure uniform load on the main beam of the crane bridge. Generally, the maximum wheel pressure should not exceed 20% of the average wheel pressure.

4. The mechanism on the trolley frame must match the trolley frame properly. In principle, the design should focus on the mechanism, and try to use a trolley to match the mechanism; at the same time, the layout of the mechanism should also be as convenient as possible to design and manufacture the steel structure. Because the trolley frame is to house and support the lifting mechanism and the trolley operating mechanism, the trolley frame should be designed according to the requirements of the lifting and operating mechanism. However, without affecting the work of the mechanism, the layout of the mechanism should also match the requirements of the trolley. The design of the frame makes its structure simple, reasonable and easy to manufacture.

Note: In addition to meeting the above conditions, it must also meet the standards of the local Quality and Technical Supervision Bureau to be considered qualified.
