YZ metallurgical overhead crane

The YZ metallurgical overhead crane, manufactured by Chunhua Crane (Hefei Chunhua Hoisting Machinery, China, founded 2003), is a purpose-engineered material handling solution designed specifically for the demanding environments of steelmaking and continuous casting processes. This crane serves as a critical piece of primary equipment in steel mills, tasked with converter feeding, transferring molten iron from mixer to converter, hoisting molten steel to refining furnaces, and lifting ladles to continuous casting rotary platforms. The core strength of the YZ series lies in its robust, heat-resistant construction and high-duty-cycle performance, engineered to withstand extreme temperatures, heavy slag accumulation, and the repetitive shock loads inherent in molten metal handling.

The YZ metallurgical overhead crane is built to handle a standard rated capacity of 75 tons, with a span range from 7.5 meters to 31.5 meters and lifting heights adjustable between 6 meters and 30 meters to suit varying workshop configurations. The crane features a double-girder box structure fabricated from high-strength steel, designed to minimize deflection under full load while maintaining torsional rigidity. The main hoist mechanism is equipped with a dedicated metallurgical-grade winch, incorporating a dual-brake system and a slow-speed micro-motion function for precise ladle positioning. The electrical control system can be specified with either Schneider or Siemens components as optional upgrades, providing reliable variable frequency drive (VFD) control for smooth acceleration and deceleration. Standard control modes include pendant handle control, wireless remote control, and an operator cockpit with full visibility. Safety devices are comprehensive and include overload limiters, travel limit switches, emergency stop circuits, anti-collision buffers, and a dedicated high-temperature protection system for the motor and electrical cabinets. Optional features include a centralized lubrication system, a closed-loop load monitoring display, and a corrosion-resistant paint scheme for high-humidity environments. The crane is designed and manufactured in accordance with GB/T 14405 and GB/T 3811 standards, and can be certified to CE, CCC, FEM, DIN, or CMAA requirements upon request.

Beyond the core steelmaking application, the YZ metallurgical overhead crane serves a diverse range of heavy industrial sectors. In steel mills and foundries, it handles molten metal ladles, scrap charging buckets, and mold preparation. In non-ferrous metal smelters, the crane manages heavy crucibles and furnace charging operations. Large-scale metal fabrication workshops use the YZ series for moving massive dies and press components. Port and shipyard facilities deploy the crane for heavy lifting of steel coils, slabs, and structural components. Heavy machinery manufacturing plants utilize the crane for assembly and maintenance of large equipment. Finally, warehouse and logistics centers handling oversized or high-density cargo benefit from the crane’s precise control and high load capacity, making it a versatile solution for any operation requiring reliable, heavy-duty lifting under harsh conditions.

Choosing Chunhua Crane as your YZ metallurgical overhead crane supplier delivers a direct factory pricing advantage, typically 30 to 50 percent below equivalent European or North American brands, without compromising on engineering quality or component sourcing. Our engineering team provides non-standard customization for any span, lifting height, or control configuration, and we commit to a four-hour quotation response time after receiving your inquiry with basic site dimensions and load requirements. All cranes are available with CE or CCC certification, and we can engineer to FEM, DIN, or CMAA standards as needed. With over two decades of continuous operation since 2003, we have exported to more than 60 countries, supported by a logistics network that handles sea freight to major ports worldwide, including optional on-site installation and commissioning supervision by our experienced technicians.

The ordering process is straightforward and designed for international buyers. Begin by sending your inquiry via WhatsApp or email with your required capacity, span, lifting height, and preferred control mode. Our sales engineering team will respond with a detailed quotation and preliminary CAD drawing within four hours. Upon acceptance, a 30 percent deposit via T/T is required to initiate production. Manufacturing typically takes 30 to 45 days, depending on customization complexity. After production, the remaining 70 percent balance is due before shipment. We arrange sea freight to your designated port, and an optional installation and commissioning service can be included in your order. Contact us directly to begin your project evaluation.
