Weihua made a 600t gantry crane for a hydropower project and this crane was successfully installed and delivered on the customer site. This product is independently developed, designed, and produced by Weihua, and is mainly used for the hoisting of offshore wind power pipe piles, tower barrels, wind blades, and other equipment. It has effectively promoted the development of the local clean energy system, which is helpful for promoting carbon peak and carbon neutrality.
Features of Weihua 600t Gantry Crane: 1. It has lightweight design, compact structure, light weight, low wheel pressure, and low energy consumption. 2. It adopts frequency conversion control, ensuring smooth lifting and operation, low impact and low noise. 3. High quality components are used, the crane is equipped with a hardened gear reducer, steel drum, rolling pulley, and 65Mn forged wheel. 4. The crane is equipped with a electrical deviation correction device to ensure synchronous operation of both cranes and achieve automatic deviation correction. The crane is also equipped with electronic control technologies such as safety monitoring. 5. Variable span, which can be changed from 40m to 50m as needed.
ArcelorMittal Steel Group is the world's largest steel producer. The lifting products were all European brand products before purchasing from Weihua Group. It is the first time for Chinese companies being listed as qualified suppliers of ArcelorMittal. The images shows the installation of bridge cranes for ArcelorMittal Project in Ukraine.
In the crane industry, it is known that crane is able to operate to 6 directions: up and down, left and right, front and rear. But do you know the rotating scrap feeding crane? Now I take you on a new skill of the rotary scrap feeding crane.
The born of rotary feeding crane solves the problems of space limitation of production workshop, large tilting angle of material trough and big tonnage of scrap feeding. It has the features of 270 degree rotation, strong operability, high safety factor, high stability and low friction, which is suitable for the metallurgy and steel industry.
After knowing this crane, you must be curious about its background? Next, I will tell you about this crane 'born' history.
Facing the challenges:
1. The trough is close to the wall, so the hook can only work in a small space;
2. The opposite side of the cabin is a flame-covered ladle, and the structure has high requirements for fire resistance and heat resistance;
3. All dumping of the scrap is required at one time, and the tipping angle of the trough shall be more than 60 degrees.
The Weihua Technology R&D team has overcome many technical problems and finally completed the design, fabrication and delivery. Weihua's first rotary scrap charging crane was successfully launched, and successfully carried out the running test of this special equipment. This project is a new breakthrough in product research and development in the steel feeding industry.
It is reported that due to the stable performance of the rotary feeding crane, another one is required and will soon be 'born'.
Event: An LH-type electric double girder bridge 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 bridge 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 bridge 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!
This safety monitor consists of 3 parts: vibration sensor, edge controller, and cloud computing platform. The sensor is installed in the position of high-speed rotation machinery (such as reducer, motor) of the crane, with advanced signal analysis and AI expert intelligent diagnosis technology to achieve predictive monitoring and diagnosis of motor and reducer failure, equipment health assessment, equipment life forecast, etc. It provides solid guarantees for efficient and safe running of equipment.
Core Technology: 1. Redundant data reduction and dimension compression technology: Effective data is extracted for massive data, eliminating low-value data, and ensuring high-quality data storage, which is more conducive to model establishment and software development. 2. CNN Lack Data Reconstruction Technology: Recover the data deletions caused by faults such as sensor failure, which has less errors and close to the real level. 3. Data fusion, time-frequency feature extraction technology: Data features are extracted in 2 aspects: time domain and frequency domain, and different feature information is extracted for construction model. 4. Advantage upgrades: Weihua has aware of the needs of customers, and has made targeted research and development and technological innovation. This safety monitor device has significant technical advantages such as magnetic installation, high-speed collection, strong anti-interference, and large operating storage space.
Recently, a double girder bridge crane(Model: QD160/32-18m) exported to Ukraine is being tested in Weihua factory. The Ukrainian side sent a supervision team to work in coordination with Weihua project team. Our engineers and sales staff actively communicated with the Ukrainian supervisors and conducted in-depth discussions on various details.
This 160t bridge crane is used outdoor for crusher maintenance and other equipment handling for a mining and metals company in Ukraine.
Founded in 1988, Weihua Group is a leading crane manufacturer in China. Weihua has been committed to heavy machinery researching and marketing. The crane product includes bridge crane, gantry crane, electric hoist, project crane, container crane, etc. Weihua products have been exported to Britain, France, Australia, Russia and other 129 countries and regions.
These cranes has large span and heavy self-weight. So there are 7 trucks were used for this inland transport to Tianjin Port from Changyuan City. After 650km transport in 8 hours, the cranes were successfully reached Tianjin Port.
The delivery of the bridge cranes to Mexico once again got the recognition and trust from clients in the North American market.
