You can easily find Weihua bridge crane for tunneling shield production, which are used for the loading, unloading, turning and launching of tunneling shield.
Weihua cranes have served many landmark shield machines in China. In the future, Weihua Crane will continue to conduct in-depth product and market research, and actively expand product features, to promote China's high-end equipment manufacturing industry.
World first horseshoe shield machine 10.95 m × 11.9 m
Guangxi Laibin Yinhai Aluminum Co., Ltd. was established in December 2006, is a key project of the Guangxi Autonomous Region, which is also the leading project to build Guangxi and even the national aluminum deep processing base.
Electrolytic aluminum multifunctional crane is the key equipment in the production of electrolytic aluminum, which can carry out the process of shelling, anode replacement, fishing residue, feeding, aluminum discharging and other process operations. It has complex structure, multiple function, and with hydraulic, pneumatic and other subject knowledge.
In the design phase, our company set up a special technical team carrying out a greater breakthrough in the key technology among which the slagging mechanism uses a double cylinder drive. This crane has big under pressure of the grab, easy maintenance. The screw motor to replace the anode body is directly installed in the screw head frame. We cancel the spline drive shaft and cross coupling, reducing the failures and enhancing the torque. Shelling mechanism using four-link pole and the rear dual-cylinder drive structure can achieve hit electrolytic shell seam, while enhancing the structural strength. Slag body is set in the main rotary frame, which rotates with the main rotation, easy to grab the slag.
In the product process, the Ministry of Technology made detailed research on the design drawings for detailed cutting, welding, machining, assembly and other technology programs, and made full use of welding platform, special process tooling, tailored heat treatment and machining to ensure the manufacturing process accuracy.
In the production stage, engineers and technical staff timely solved the problems encountered in the production process, the team workers actively learn the drawings, overcome difficulties to ensure product quality.
The Guangxi Laibin Yinhai Aluminum project contains a total of 10 electrolytic aluminum multifunctional cranes. The successful completion of the first crane in the project is inseparable from the leadership's attention and the joint efforts of all the staff of the project team. The crane has made a breakthrough in technology and has successfully laid the foundation for the production of follow-up products and further enriched the Manufacturing experience in the field of dedicated crane for aluminum industry.
Recently, Weihua Group signed a contract of making a High-Precision Automatic Intelligent Bridge Crane for Shanghai Mingjiang Intelligent Systems Co., Ltd. The crane positioning accuracy is ± 4mm.
The crane will be used by China Vehicle Group for Chengdu electric locomotive generator stator core assembly, which requires high positioning accuracy. To achieve unmanned intelligent operating in assembly operations area, it uses a programmable automatic control technology and servo control technology to control the crane, the crane lifting mechanism is arranged so that during operation spreader is not swing, balance up and down without offset.
This High-Precision Automatic Intelligent Crane not only effectively improve the production efficiency, but also realize intelligent material handling, while reducing labor costs.
This is the first time Weihua Group cooperates with Industry 4.0 Design Institute. After once technical exchange, Weihua was pointed as the manufacturer, which also reflects our company's overall level of R & D and design capabilities.
Currently, high-precision automatic cranes research in China is still in its infancy, the cooperation will greatly improve our strength to develop intelligent automatic crane.
Recently, Weihua Group successfully developed a heavy duty 320T crane reducer delivered to user. The reducer length 10m, height 2.2m, width 1.3m. It adopts hard-toothed gear transmission technology and reaches China advanced level. The reducer has the features of large carrying capacity, high transmission precision, convenient installation, long service life and simple maintenance, and the structure adopts double-input and double-outlet form, and the middle connection is by the meshing wheel to realize synchronization at both ends.
The traditional metallurgical crane usually has 2 reducers connected by coupling to realize the synchronous lifting of the two reels. This form has higher requirements on the processing, installation and debugging accuracy of the trolley, and the system rigid is not enough. While the 320T crane reducer greatly enhances the mechanical transmission accuracy, reduces the probability of parts failure, and improves the crane operating efficiency.
Together with the H series hardened gear reducer, new K series, F series gear reducer and new European crane lightweight reducer series, the 320T crane reducer is another Boutique of Weihua Brands. This product meets the users’ demand for high precision gearbox. It is of great significance in the lifting industry and in general-purpose machine.
The advent of the 320T crane reducer represents our ability to produce a wide range of 200-500 tons of large metallurgical cranes. Weihua will continue to strengthen technology research and development and innovation, maintaining quality and service advantages in crane parts and transmission machinery products.
China's Long March 5 Rocket launched at the Wenchang space launch site and the practice 20 satellite was accurately put into the predetermined orbit.
In this launch mission, the bridge cranes produced by Henan Weihua Heavy Machinery Co., Ltd. undertook the key link of rocket assembly jobs, including hoisting, transportation, overturning, and testing of Long March No. 5 in the factory building with high accuracy, helping the rocket launching successfully!
Weihua lifting cranes has long served China aerospace engineering, successfully completed several rocket assembly tasks, and won unanimous praise from the customer.
The world highest generator stator lifting was successfully completed in a power plant in Shaanxi Province, China. This lifting task is carried out by 2 sets 170-ton bridge cranes with a lifting height of 80m.
The weight of the generator stator is 290t and the height of the layout platform is 65m, which makes it the world's highest platform. Therefore, the project has extremely high requirements for the lifting cranes.
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.
This time, Weihua cranes replaced the orange coat to white color to match the uniform color of the power plant, and complete the lifting task.
