500 Tons Ladle Crane Quality Assessment

On July 5, 2022, Weihua made a new metallurgical ladle crane with capacity 500t and the main structure was successfully finished. The quality assessment was held in the production workshop. It once again refreshed the manufacturing record of Weihua's metallurgical cranes.



The crane is designed for a metallurgical workshop of an Iron and Steel company, with a 4-girder 6-rails structure, lifting capacity: 500/90/15t, span: 20.7m, working duty: A8. It is the first capacity 500t metallurgy industry bridge crane independently developed by Weihua.



Weihua carried out the whole fabrication process control from pretreatment-unloading-welding-finishing-assembly to test. Using the overall boring and milling processing of large structural parts, overall annealing and assembly of the main trolley frame and the gearbox. It proved again Weihua has a mature and reliable production process and quality assurance system for large and super-large metallurgical cranes.



In the on-site quality assessment meeting, the crane appearance, camber, web verticality, waviness, wheel parity and other parameters were comprehensively tested, and all of them passed the review successfully:

1. Pass rate of non-destructive testing of all welds is 100%;

2. The camber, the height difference of the same section of the track, the wheel line, the track gauge of the trolley, and the straightness of the track are 100% qualified.

Intelligent Crane for Electrolytic Copper Industry Has Good Performance

The special electrolytic copper crane independently developed by Weihua was successfully delivered to a project in Guangdong. As the biggest highlight of this crane, the special lifting spreader for copper electrolysis 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 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 crane has 3 operation modes: fully automatic, semi-automatic and manual;

2. The crane adopts frequency conversion and PLC precise control, with high-precision positioning;

3. The cab can synchronously monitor the insulation status of spreaders, motors, transformers and other devices, and give an alarm when leakage occurs;
