2013 hot sales L model gantry cranes with trolly

It is a kind of heavy duty crane ,it is widely used in plants, steel factory .warehouses, materials stocks to lift goods or materials.

this crane mainly consists of strong bridge beams,crane traveling mechanism, electric winch trolley and electric system,

and could be classified into several working duties,e.g.A5,A6,A7,according to the working frequency and pure working time.

Main girder

The main girder includes girder box, platform, pantograph and trolley rail.

The Main girder will be strictly fabricated and detected in our workshop according the design and national standard.

The toughness and strength are perfect combination. It applies shot blasting and high quality painting.

Well-chosen choose steel plate, advanced welding technology and equipment.

Trolley

The trolley are assembled with motor, reducer, brake, trolley frame, drum, hook, pulley, rain cover and other parts.

It includes lifting mechanism and cross traveling mechanism. The trolley is strictly designed according to the application and working environment.

End Beam

The Ground Beam works as long traveling mechanism, and it combines with beam, Wheel, Motor, Reducer, Brake and Other Parts.

The steel plate adopts shot blasting and high quality painting.

High quality raw material. The end beam are connections with bearing beams.

Cab control

In general, Cab control is used in the heavy tons, because it is so expensive. However, it is the most comforable one in the three.

The driver in the cab controls everything, there are comforable chair and all electric parts.

No matter what happens, all working worker must obey the driver's instructions.
