Five Types of Bridge Cranes, which participate in specific process operations in the steel production process and have a basic structure similar to that of a standard bridge crane.

Cast Crane

Used for transporting molten iron into the mixer furnace, steelmaking furnace, and for transferring molten steel into continuous casting machines or ingot molds, etc. The main trolley carries the containers, while the auxiliary trolley performs flipping and other supporting tasks.

Clamp Crane

Using a clamp, the high-temperature ingots are vertically lifted into the deep pit homogenizing furnace or removed and placed onto ingot transport carts.

3. De-coiler Crane

Used to forcibly remove steel ingots from the ingot mold. The trolley is equipped with a specialized de-inking device, and the de-inking method depends on the shape of the mold: some use a pushing rod to hold the ingot, lifting the mold with a large clamp; others hold the mold with a large clamp and lift the ingot with a small clamp.

4. Material Handling Crane

Used to add furnace charge into the furnace. The lower end of the main trolley's pillar is equipped with a lifting rod, which is used to lift the charge box and deliver it into the furnace. The main pillar can rotate around a vertical axis, and the lifting rod can swing up and down and rotate. The auxiliary trolley is used for auxiliary tasks such as repairing the furnace.

Forging Cranes

Used in conjunction with hydraulic presses for forging large workpieces. The main trolley features a hoist with a turnover device for supporting and flipping the workpieces; the auxiliary trolley is used to lift the workpieces.
