Ladle Handling Crane

The ladle handling crane is the main lifting and transportation equipment in smelting workshop and continuous casting workshops of the steel plant, it is mainly used for lifting liquid metal (mixing molten iron and receiving molten steel). The working environment is harsh, high ambient temperature, heavy dust level and extremely working duty. Weihua 50 ton to 550 ton ladle handling cranes are designed and manufactured in accordance with FEM, DIN and GB standards and company continuous innovations, is a safe, reliability and high performed crane for steel mill productions.


The ladlecrane structureforms mainly consist of four-beam and four-track double trolley, four-beam and six-track double trolleyfor crane load capacityover 200 tons and double-beam single trolley, and double-beam main and auxiliary trolleyfor crane with work load below 200 tons.

Double beam overhead metallurgy crane is mainly compsed of bridge,crab,connecting traverse,trolley travelling mechanism and electric part. The main hook employs the constant-spacing connection traverse as the load handling device to hoist steel ladle and the auxiliary hoisting.The ausiliary hook acts in concert with the main hook to accomplish pouring of molten steel and steel slag,and other auxiliary hoisting.

Casting cranes with work load above 300 tons adopt the overall large reducer model, which improves the stress situations of the main trolley, avoids the disadvantage of excessive pressure on the main trolley, and can obtain a smaller left and right limit of the trolleyand improves the safety and reliabilityof the lifting mechanism.

Small and medium-sized casting cranes canadoptdouble-beam and double-track single trolleys, double trolleys, main and auxiliarytrolleys. With advantages oflight deadweight, small size, and large limit size on one side.

Main Features and Benefits of Weihua Ladle Handling Crane

1.It adopts Siemens PLC and Siemens inverter for control and drive. At the same time, Profinet is used for communication between PLC and inverter. It is equipped 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 crane in real time.

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

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

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

6.The 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 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.
