Electrical Control System:
1. Digital frequency conversion and PCL control;
2. High Precision Sensor Data Acquisition Technology;
3. Industrial computer data analysis and processing system.



Operation Flow:
1. The container handling instructions are sent from the central control room to the working crane.
2. The driver cabine receives the instructions.
3. The crane driver starts the loading and unloading operation by the linkage table touch screen.
4. Touch screen real-time displays the spreader, crane and trolley position.
5. The control system temporarily receive plug-in jobs, while it gives priority to the ongoing job, then perform the plug-in job after finishing the current job.
6. Precise container positioning technology.
Machine vision accurately identify the location of container keyhole and read the container number, then intelligent control system adjust the spreader position and deflection angle to realize accuracy locking and precision container stacking.
7. Linkage table touch screen real-time displays the spreader, crane and trolley position.
8. This crane is equipped with PDS system, if the crane position does not correspond to the indication position from the PDS system, the crane does not execute the command, and sends out the alarm information. After the driver moves the crane to the system indication position, the crane continues to execute the handling command.
9. Programmed path planning and obstacle avoidance technology for optimizing path and obstacle avoidance.
10. The use of infrared space scanning carry out real-time scanning of 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 working.
11. The central control room receives the completion information feedback of the crane and sends it to the database.

Overhead Crane Destructive Test in Mongolia

Rated load 20t; while overload 27.7t

Time: June 5, 2019
Location: Ulaanbaatar City, Mongolia
Event: An LH-type electric double girder overhead crane with a rated load capacity of 20t is undergoing acceptance test.

Moment: 14:30
The crane test began.
After successfully passing the no-load operation, the crane statically loads the 20t steel plate hangings. After 10 minutes, the crane load moves back and forth and left and right. After strict testing by the test personnel, all aspects of the crane performed well and passed the tests smoothly.



Moment: 14:55
In order to verify the performance of the crane, the customer temporarily decided to increase the weight of the load for the destructive overload test.

The steel plate was slowly added to 24t, and the crane began to lift for static load test. Engineers and workers are hiding outside the factory, and they are far away from the gate, leaving only our engineers and testers to continue testing. 1 minute, 2 minutes, 3 minutes...10 minutes, the crane successfully completed the static load test. The hoist moves left and right, the crane moves forward and backward, and the crane successfully completes the 24t dynamic load test. Weihua crane successfully passed another test!



Time: 15:15
The trial is not over yet! Customer continue to increase weight!
24t, 25t, 26t... The weight of the hanging object finally stayed at 27.7t, and the crane started another challenge! The on-site personnel who had been hiding outside the factory slowly began to approach. Lifting and holding, everyone at the site is watching the state of the crane; the crane moves left and right, back and forth, and everyone's attention follows the test. In the end, Weihua lifted its expectations and succeeded in passing the challenge again!

The measurement of infrared instruments shows during the test, the degree of crown, side bends and other aspects of Weihua Crane have reached international standards. After the test, the entire system staff gave a thumbs up, and the manager said: OK! OK! Very Good!

Gantry Crane for Subway Construction / Weihua Crane

With the rapid development of the economy, population and the rapid growth of motor vehicles, many cities have emerged a serious 'urban disease' - a large traffic jam. Subways come into being. Because the subway is comfortable, fast and convenient, it is becoming an important parts of transport in many urban cities.

With the fast development of subways, the construction machines, especially the cranes, are becoming an important role for the subway construction. Weihua has rich experience and many project cases on subway construction gantry crane.

Subway gantry crane for slag handling is used for subway tunnel construction. This crane is mainly responsible for the construction of the subway tunnel, lifting the dregs excavated by shield excavator to the ground. Features of subway slag gantry crane:
◆ variable span, improve crane utilization;
◆ cantilever detachable, more practical;
◆ running fast, high work duty, high efficiency;
◆ high lifting height;
◆ with special tilting spreader with automatically tipping.



1. The gantry crane for subway construction is used for dealing the dregs and site material handling during subway construction.
2. With the span-changed function of Min. step-length 100mm, this subway construction gantry crane is suitable for various working conditions.
3. The cantilever is detachable, also can preserve the cantilever interface which will be flexible for different working conditions.
4. There is lightning protection system, wind speed detection warning system.
5. The gantry crane for subway construction is equipped special spreader and realize the interchange of dregs bucket and the hook.
6. With the overturn hook, it realizes overturning the dregs at any position in the air. Overturning dregs system is controlled by the hydraulic which makes the overturning process more stable.
7. The trolley is rotatable, and can realize the front, side transporting dregs.
