Weihua Portal Crane Can be:

1. Port Portal Crane: This crane is equipped with a replaceable hook, grab and other spreader, as well as bucket, funnel or belt conveyor for material handling.

2. Ship Construction Portal Crane: For the lifting work at shipyard with a large lifting capacity and lifting height. Usually 2 or more lifting hooks are fitted on this crane. The lifting weight of the main hook vary with the range of work. The working speed is generally slower than that of port portal crane.

3. Container Portal Crane: Used for container handling and stacking at container freight yard.

 

 

Features of Weihua Portal Crane:

1. Spreader: grab or hook, good applicability;

2. 4-bar linkage boom, precise luffing. The 4 bar linkage mechanism is optimized by dynamics software. When luffing, the horizontal move of load is ensured, the transmission angle is increased and the pressure angle reduced, by which, the service lift of 4 bar linkage mechanism is increased.

3. 360° slewing, wide working area;

4. PCL control, AC frequency speed control, stable and reliable operation;

5. Remote control is available if necessary;

6. Enough protection devices, communication and lighting system;

7. Adopt electronic balance system to prevent overload of opening and closing mechanism and lifting mechanism;

8. The luffing mobile counterweight is adopted so that when operating, the upsetting moment caused by load is minimized and the service lift of revolving support is increased.

Wood Handling Crane / China Leading Crane Manufacturer

 In November 2017, the MG66t wood handling gantry crane manufactured by Weihua Group was shipped to Russia and completed the installation, which works with the timber loader manufactured by the German Sunni Bergen Group at paper mill. The crane not only needs to meet the requirements of low temperature environment, but also fully matches the performance of the Sunni Bergen loader, and satisfies the stability and balance of the loader arm length, lifting and 360 degree rotation in the working range. And the electrical control system of the crane should be docked with the electrical control system of the loader to complete the work.

The customer's high-tech standards also put forward higher requirements for Weihua. Weihua strictly controlled each weld seam according to the process requirements, and the whole crane was subjected to ultrasonic weld flaw detection, and the connection chassis of the loader and the trolley was carried out at the installation site with precise connection. In the extreme environment and strict requirements, it is a new challenge and a huge test for our products.
