This bridge crane is a capacity 500 tons 4-girder 6-Rail Metallurgical Crane independently developed by Weihua Crane. This time, only the main structure of this crane was delivered to a large steel company with steel production capacity reaching 6.5 million tons.
Features
It adopts strict and high-standard full-process control, overall processing of large structural parts, overall annealing treatment of the main trolley frame and the heavy-duty gearbox, and the overall assembly, thus the equipment stability is higher.
The electrical system uses advanced energy feedback technology, and the power generated by heavy machine loads is reused, which has greatly improved the energy utilization rate of equipment.
Recently, Weihua made a 500t gantry crane for a heave equipment company and this crane has successfully passed the acceptance inspection, adding a new member to the Weihua Large Tonnage Product List.
This product is mainly used for large-scale equipment lifting and the Max. 500t objects can be easily lifted. The span is 40m, and the lifting height is 40m, which means that the objects can be lifted to a height of about 14 floors.
1. Gantry structure adopts the lightweight design of equal strength, and the product has sufficient stiffness and overall stability, with wind resistance, earthquake resistance, and anti overturning capabilities.
2. Each mechanism adopts frequency conversion+PLC control to achieve slow and fast operation under full load and light load. It is equipped with a safety monitoring system and has functions such as task management, status monitoring, recording, storage, browsing, and tracing.
3. Multiple lifting points are combined for lifting, achieving high-precision synchronization, and equipped with upper and lower electrical deviation correction devices to ensure synchronous operation of both sides of the crane.
Carrying out heavy load operations in an outdoor working environment places higher demands on the stable operation, efficient and reliable use characteristics of equipment, and this company is located in the coastal area frequently affected by adverse weather such as typhoons. With excellent product quality and ingenious service guarantee, Weihua has built a strong safety fortress for customers. Its products can withstand typhoons of magnitude 12 and earthquakes of magnitude 7, eliminating worries for customers.
Weihua made anautomated bridge crane for electrolytic copper industryin Guangdong, China. The highlight of this crane is the special lifting spreader which is used for the automatic discharge and loading of cathode (starting plate) and anode plate. It has the advantages of multiple functions, high automation, reliable insulation, stable performance, etc.
The crane spreader is independently developed by Weihua. Its main structure is made of high-quality stainless steel, with high strength, acid corrosion resistance, excellent quality and greatly reduced cost. It is really the best choice for users to reduce costs and increase efficiency. In addition, the spreader also has the following features:
1. Specially designed plate arrangement function and discharging device ensure that the initial cathode plate can be smoothly put into the tank;
2. It can meet the requirements of separate lifting and overall joint lifting of cathode plate and anode plate, with high efficiency;
3. The method of combining pre positioning with precision positioning is adopted, and the positioning accuracy is ± 2mm;
4. The opening and closing of the flat push type liquid receiving tray are stable to ensure that the electrolyte does not splash out.
Weihua has strong processing equipment. Only with strong processing capacity can it meet the complex processing needs of special lifting appliances for copper electrolysis.
There are many highlights in the design of spreader, and the comprehensive design of the main crane is also a masterpiece. It is equipped with a fully automatic operation system, with high operation efficiency, convenient operation and advanced performance.
1. The bridge crane has 3 operation modes: fully automatic, semi-automatic and manual;
2. The bridge crane adopts frequency conversion and PLC precise control, with high-precision positioning;
3. The cabin can synchronously monitor the insulation status of spreaders, motors, transformers and other devices, and give an alarm when leakage occurs;
4. The 4-motor structure of traveling crane meets the deviation correction function and greatly improves the stability and reliability.
