Weihua Crane Assist Launching of Carrier Rocket Long March 5B

On May 5, the Long March 5B carrier rocket developed for China's manned space station project made its first successful flight in Wenchang, Hainan. In this launch mission, Weihua crane provided the rocket with high-precision hoisting and transshipment protection with advanced technology.

In Hainan Wenchang Satellite Launch Base, Weihua Group's over cranes undertaken the key link of rocket transfer and hoisting, and completed the handling, turning, and testing of rockets in the plant with high precision. Although the cranes are big and sturdy, their lifting accuracy reaches an astonishing 2 mm. The secret is that they have a sensitive Brain that can pass through the needle thread-equipped with anti-sway technology independently developed by Weihua, which can reduce the amplitude of swing by 95% and improve the stability and accuracy of the rocket during lifting.

Weihua lifting equipment has been serving aerospace engineering for a long time. It is the contractor of lifting equipment for 4 China satellite launch bases in Jiuquan, Taiyuan, Xichang, and Wenchang, helping the detector, the Long March rockets, the Mozi, and the Shijian 13 satellite successfully flew to the sky. In the journey accompanying the development of China's aerospace industry, Weihua Crane has accomplished all tasks excellently with the advanced lifting technology, excellent quality assurance, responsible professional attitude and perfect after-sales service, and has been unanimously agreed Praise and have won major contribution awards many times.

Motor Stator Handling Crane 170t 80m for Power Plant

In March, the world's first high-level generator stator hoisting was successfully completed in a power plant in Shaanxi Province. This task is completed by the joint operation of 2 Weihua 170-ton overhead cranes with a lifting height of 80 meters.

The weight of the hoisted generator stator reached 290 tons, and the height of the layout platform reached 65 meters, making it the world's highest layout platform. Therefore, the project has extremely high requirements for the lifting equipment used.

The large tonnage, super-large lifting height and super-high lifting accuracy of the 660MW steam turbine generator set mounted on the world first boiler have become an essential element of the Weihua cranes in this project.

In order to match the uniform color of the customer's plant, Weihua products replaced the orange coat to white color to complete their lifting operations seriously. With its solid quality, Weihua products perfectly combine the mechanical design and the electrical design to take on the heavy responsibility of this project case.
