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.
