 Single beam bridge crane is currently the most widely used lifting equipment for overhead material handling, mainly used in indoor and outdoor warehouses, workshops, docks, workshops and open-air storage yards, etc. It is a kind of bridge crane running on the elevated track, the bridge runs longitudinally along the track laid on both sides of the elevated track, and the lifting trolley runs horizontally along the track laid on the bridge. Form a rectangular working range, can make full use of the space under the bridge to lift materials, not hindered by ground equipment.

LD model single girder overhead crane is characterized by more reasonable structure and higher strength steel as a whole crane. Single girder overhead crane is more typical when lifting capacity less than 20T.
 

 

Electric hoist:

 light and small lifting equipment driven by electric drive, driven by reel and pulley, small volume, light weight, easy operation and maintenance

 

The connection mode of the main beam and the end beam: one is the way of adding the connecting plate and welding, and the other is the way of connecting the bolts with load reducing flanges at both ends of the main beam.
 

 

Used together with CD1  model MD1 model electric hoist as a complete set, it is a light duty crane with a capacity 0.5 ton ~ 32ton. The span is 7.5m~ 22.5m. Working duty is A3~A5, working temperature is -25-40ºC. 
 

 

We have comprehensive standard equipment and professional design engineers to offer best solutions for individual requirements.
 

1. We have the senior crane design engineers, with professional design. And very expert crane mechanical and electrical installation engineer team.

Advantages of a single girder overhead crane design:

1,Less expensive due to a simpler trolley design, reduced freight costs, simplified and faster installation, and less material for the bridge and runway beams

2,Most economical option for light to medium-duty cranes

3,Lower loads on the building structure or foundations due to a reduced deadweight. In many cases, it can be supported by existing roof structure without the use of additional support columns.

4,Better hook approach for both trolley travel and bridge travel

5,Easier to install, service, and maintain

6,Ideal for workshops, warehouses, material yards, and manufacturing and production facilities

7,Lighter load on runway rails or beams means less wear on the beams and end truck wheels over time

8,Great for facilities with low headroom
