Ladle handling overhead crane is one type of metallurgy crane, which is designed for transporting, pouring and charging hot metal in the process of smelting liquid metal, etc.
According to the crane structure, the ladle overhead cranes can be classified into double girder double rail overhead travelling ladle cranes, four girder four rail overhead travelling ladle cranes, and four girder six rails overhead travelling ladle cranes. The front two types are used for lifting middle and large scale ladles, and the latter one is used for extremely large scale ladles. SEVENCRANE know the hazard and challenge of metals production industry and can offer customized ladle handling overhead crane as per client’s requirements.
A ladle handling crane lifts large, open-topped cylindrical containers (ladles) filled with liquid metal to the basic oxygen furnace (BOF) for mixing. The raw materials of iron ore and coking coal are combined to produce solid metallic iron, and this iron added to scrap metal creates steel. The crane also transports the liquid iron or steel from the BOF and electric arc furnace to the continuous casting machine.
Ladle handling crane is designed specifically for the extreme environment of heat, dust and hot metal in a melt shop. Therefore, it include features such as Increased working coefficients, a differential gear reducer, a backup brake on the rope drum, and motion limiters making the crane and application safe and reliable. It can also be used for teeming and casting.
Wire rope adjustment device. The lifting mechanism adopts a single drive dual drum structure, which can ensure the synchronization of dual lifting points. And a steel wire rope adjustment device is installed, which can quickly level the lifting tool.
Anti sway technology. The entire machine is equipped with rigid guide pillars and horizontal guide wheel devices, which have anti sway and precise positioning functions.
Intelligent control system. The control system is equipped with wireless remote control and ground central control, and adopts large brand wireless communication equipment to achieve information exchange between the remote control station and the overhead crane, with remote control and fully automatic control modes.
High precision positioning. The positioning system adopts absolute value encoder and position detection switch, which can automatic correction to avoid accumulated errors and achieve high-precision positioning.
Safe and efficient. The control system receives instructions from the upper system to achieve fully automatic operation, with functions such as stable operation, light lifting and handling, rapid quenching, and collision prevention.
