YZ Type Casting Bridge Crane

With its robust structure, redundant safety features, specialized heat insulation protection, and advanced electrical control system, the YZ Type casting bridge crane is essential for ensuring safety and improving efficiency in steel and metallurgical processes. When selecting a crane, it is crucial to fully consider the specific working conditions and process requirements of your workshop and communicate thoroughly with professional manufacturers. This ensures the selected crane not only meets production demands but also maximizes operational safety.

Features of the YZ casting bridge crane：

The design of the YZ casting bridge crane fully addresses the special requirements of the metallurgical industry:

Robust Structural Design: Utilizes a double-girder or quadruple-girder structure to ensure stability and reliability under heavy loads and high-temperature environments.

Multiple Safety Protections:

·Overspeed Limit Switch: Prevents the hoisting mechanism from exceeding speed limits.

·Electronic Scale and Overload Limitation System: Displays the load weight in real time and triggers an alarm or cuts off operation in case of overload.

·Dual or Multi-Drive Systems: The main hoisting mechanism may employ two independent winch systems, allowing one set to complete the cycle temporarily if the other fails. The trolley travel mechanism often adopts a four-corner driving configuration.

Emergency Stop System.

Special Heat Insulation Protection: Heat shields are installed under the main girder to reduce thermal radiation from molten metal. The electrical room on the girder may also be insulated with rock wool and equipped with cooling fans.

Advanced Electrical Control and Monitoring:

·PLC Control: Enables precise speed regulation and control of all mechanisms.

·Fault Diagnosis, Display, and Recording Functions.

·Weight Display: Available in the operator's cabin and on the bridge.

Flexible Operation Modes: Supports cabin operation, remote ground control (wireless), and ground pendant operation.

Various optional functions: Advanced features such as spreader rotation, adjustable hook distance of the spreader beam, and anti-collision systems for cranes operating in the same span can be provided based on user requirements.

Applications of the YZ casting bridge crane：

The YZ casting bridge crane is an indispensable key equipment in modern steelmaking workshops, with applications spanning multiple processes:

Converter Charging Bay: Charging molten iron into the converter.

Refining Bay: Transporting molten steel to the refining furnace.

Steel Ladle Bay/Continuous Casting Bay: Transferring molten steel to the continuous casting turret (ladle turret).

Ladle Handling, Tilting, and Slag Disposal: Tasks including transporting, weighing, and tilting ladles, as well as dumping slag and residual steel.

	Bridge Girder Assembly (Main Girder and End Beams) This serves as the frame of the crane, bearing all loads. It typically adopts a robust double  or quadruple-girder structure, with heat shields installed on the bottom to resist high-temperature radiation from molten steel, ensuring overall stability.
	Hoisting Mechanism (Core Component) This is the key mechanism for lifting and lowering loads. Composed of motors, brakes, reducers, and drum groups, it features extremely high safety redundancy. Dual braking or even dual-drive systems are often employed to ensure absolute safety during molten metal handling.
	Hook Primarily uses a lamella hook design, formed by riveting multiple cut steel plates. The failure of a single plate will not cause immediate fracture of the entire hook, providing high safety redundancy-making it particularly suitable for heavy-duty or high-temperature molten metal applications.
	Wheels Manufactured from high-strength alloy forged steel (e.g., 65Mn, 42CrMo), they undergo precision forging and heat treatment (such as tread quenching). With high hardness  and deep hardened layers, they exhibit excellent wear resistance and impact toughness. Designed to ensure load-bearing capacity and durability, they enable smooth crane operation under heavy loads. Most wheels adopt a double-flange design to prevent derailment.
