This ladle crane is the largest metallurgical ladle crane ever made in Henan Province, China. During manufacture and installation, Weihua have carried out many test which lay the foundation for manufacturing this 320t ladle crane with more technology and complex structure.

 

Main structure of this crane is designed with 4 girders and 6 rails. The features of this crane: integral processing technology and secondary assembly technology. For the first time assembly, the welding components sizes are fixed and processed by flat position welding to ensure high quality of welding seams; and the secondary assembly is for releasing welding stress before the integral processing of the bridge to ensure the stability and accuracy of product process precision. The two times assembly technologies are great help to ensure the precision of gauge, diagonal and span, as well as users' site installation.

 

 

Features of Weihua Ladle Crane:

1. It uses Siemens PLC and Siemens inverter for control and drive system. At the same time, Profinet is used for communication between PLC and inverter. It is with communication detection function, which can detect the working status of each station in real time.

2. A monitoring system is installed to monitor the working status of the ladle crane in real time.

3. The lifting mechanism of the 320t ladle crane adopts redundant system design to ensure the safety and reliability of handling liquid metal.

4. It is with wireless transmission and electronic scales, carry out real-time transmission of the weight of liquid metal.

5. The ladle crane is designed with an electric room, and an electric fan is installed in the room to ensure the safe and reliable operation of the electrical equipment.

6. The 320t ladle crane hoisting mechanism adopts the planetary reducer structure. If one motor fails, it can still complete the lifting work in a short time.

7. Mother-child trolley to realize the unmanned automatic hanging ladle and save the cost.

8. The overall design of this ladle crane is with lightweight and compact structure.

9. Low height, light self-weight, small hook limit, large working range.

10. High quality parts, durable, safe and reliable.

11. Less maintenance and repair costs.

12. Small total crane power and low energy consumption.

13. Frequency control, smooth lifting and less impact.
