Operation:

1. The container lifting operation instructions are sent from the central control room to the working crane.

2. The driver room receives the job instructions from the central control room.

3. The crane driver operates the linkage table touch screen and starts the loading and unloading operation.

4. Linkage table touch screen real-time displays the spreader, crane and trolley position.

5. Temporarily receive plug-in jobs, while giving priority to the ongoing job. Perform the plug-in job after the current job is completed.

6. Accurate container positioning technology for container accurate positioning.

Machine vision technology will help to accurately identify the location of container keyhole and container number, then intelligent control system control the crane operation, adjust the spreader position and deflection angle, to achieve accuracy spreader locking and precision container stacking.

7. Linkage table touch screen real-time displays the spreader, crane and trolley position.

8. Equipped with PDS system, if the crane running position does not correspond to the indication position of the PDS system, the driver need to drop the rocker and the crane does not execute the command, and sends out the alarm information. The crane continues to execute the handling command until the driver moves the crane to the system indication position.

9. Programmed path planning and obstacle avoidance technology for optimizing path and obstacle avoidance.

10. The use of infrared space scanning technology real-time scanning yard container storage situation, and updating yard stacking 3d database. Spreader is controlled by intelligent program to run along the optimal path for intelligent obstacle avoidance to ensure safe operation.

11. The central control room receives the completion information feedback of the crane and enters the database.

Portal Crane / China Leading Crane Manuacturer

 A portal crane is a crane with rotary boom and runs along the ground track. Portal crane allow ground vehicle or rail vehicle to run through its portal/gantry, which make enough working space for on-ground vehicles transport.

 

portal crane

 

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.
