Construction characteristics of Single Girder Overhead Crane steel structure

Electric single-beam crane mainly includes three operating mechanisms: lifting operating mechanism, cart operating mechanism, trolley operating mechanism.

The lifting operation mechanism is mainly composed of electric hoist, steel wire rope, pulley, hook or sling.

The metal structure of the electric single-beam bridge crane is mainly composed of the main beam and the end beam. The main beam structure is mainly composed of the composite section of i-beam steel and steel plate, which is composed of the cover plate, web plate and i-beam steel. In the box, there are longitudinal and horizontal reinforcing bars.

Its safety and reliability directly affect the crane's operation quality and working ability.

So what are the characteristics of the steel structure of single-beam crane?

Features of steel structure:

1) manufacturing, welding and inspection of steel structure.

Important stress butt welding seam adopts double-sided groove welding process, and according to the provisions of appearance inspection and non-destructive inspection, all welders hold the corresponding grade certificate.

2) all the main girders of cranes adopt the whole plate no-butt welding technology, which eliminates the butt welding seam of steel plate of the main girder and eliminates the hidden danger of butt welding of steel plate.

3) all the plates are automatically blanked by CNC cutting machine, and the arch of the main beam is preset to avoid the problem of bending the arch of the traditional fire baked main beam.

4) the longitudinal waist welding seam of the main girder adopts automatic special machine for ambush welding, forming beautifully to ensure the welding quality.

5) the beam of the cart is made of rectangular tubes as a whole, without splicing and welding seams. It is beautiful in appearance and durable.

6) all the wheels are installed with boring installation to avoid that the tread of the wheels is not at the same horizontal plane and improve the running accuracy of the wheels.

The above is the steel structure of the single-beam crane production characteristics, we hope to understand the single-beam crane can have a more comprehensive understanding.
