Double beam grab bridge crane is a heavy lifting machinery. When heavy loads and large spans are required, the two beam bridge cranes show their strength. They can offer 450 tons of various customer choices.


QC double beam overhead bridge crane consists of main girder, end frame, lifting platform, complete electrical system and control system.


The components used are standard equipment for well known manufacturers, and have been approved by our testing laboratories for specific crane operations. Their characteristics in impact, vibration, wear and safety are investigated. Continuous high quality standards are guaranteed by mass production and standardized components.

The electrical equipment is installed on the crane beam, in the steel plate control cabinet.

 

All movements can be controlled by the main contactor of the control station to control the emergency closing switch.

Power supply cables and control cables along the beam

Standard with protective grounding conductor. Crane switch.

End of travel switch

The long stroke and the cross stroke are restricted by the preliminary limit switch and the final limit switch.


II.Application range

The equipment is widely used in lifting operations, such as factories, mines, fixed span transportation materials, machining workshops, metallurgical plants and ancillary workshops, warehouses, materials fields, power plants and so on.


III.Safety characteristics:

1. Overload protection: if the material exceeds capacity, the crane will warn itself.

2. Emergency braking: if the operator is in an emergency situation, the emergency braking system can be started to protect the relevant treasure.

3. Control mode: Pendent wire, cabin control, remote control.

4. Main hoisting motor: with thermal protection and currency protection function.

5. Lock hook.

6. Rubber buffer.

7. Crane switch and stroke end switch

8. All cranes must undergo strict inspection and testing before leaving the factory, and provide test certification


IV. Painting

Finish painting in factory before shipment.

After manufacture (after welding)

Average thickness: about 100 microns

Electrical components

The crane we provide is designed to meet the requirements and requirements of your technical requirements, as well as the operating conditions.


Overload protection: in overload condition, the crane unit is closed, and only the descent motion is possible.

 

Control method: Pendent line. Cabin control. Remote control
