LDY metallurgical overhead crane

Technical Configuration

The LDY metallurgical crane is built to project-specific specifications, with a standard lifting capacity up to 10 tons, though custom configurations can be engineered for higher loads upon request. The span and lifting height are fully customizable to match your facility layout, with single girder construction optimized for moderate spans. The crane is driven by a heavy-duty motor system with optional Schneider or Siemens electrical components, providing precise control and reliable performance under thermal stress. Control options include cabin operation for direct line-of-sight handling, radio remote control for operator safety and flexibility, or pendant control for simple manual operation. Safety is paramount in this design; the crane incorporates multiple redundant safety devices including overload limiters, emergency stop circuits, thermal protection for motors, and anti-sway mechanisms to prevent load oscillation. The hoist features a specialized heat-resistant wire rope and brake system designed to withstand radiant heat from molten materials. Optional upgrades include variable frequency drives for smooth acceleration and deceleration, IP55-rated enclosures for dust and moisture protection, and corrosion-resistant paint systems for harsh environments. The crane is designed and manufactured in accordance with the GB/T 3811 crane design standard and complies with the special document requirements of the General Administration of Quality Supervision and Inspection (document No. 2007-375) for metallurgical lifting equipment. Additionally, the crane can be engineered to meet FEM, DIN, or CMAA standards upon customer request, ensuring compatibility with international engineering practices.

This crane serves a wide range of heavy industries where high-temperature material handling is critical. Primary applications include steel mills for transporting molten steel in ladles and tundishes, non-ferrous metal foundries for handling molten aluminum, copper, and zinc, and casting workshops for moving red-hot solid metals and sand molds. It is also suitable for forging operations where heated billets require precise positioning, heat treatment facilities handling glowing workpieces, and industrial warehouses storing hot-rolled or freshly cast metal products. The LDY crane can be adapted for use in glass manufacturing and ceramic kiln operations where thermal exposure is a factor, though the primary focus remains on metallurgical processes.

Chunhua Crane, established in 2003, offers direct factory pricing that typically undercuts European and North American brands by 30% to 50%, providing significant cost advantages without compromising on quality or safety. All LDY cranes are available with CE certification for European markets and CCC certification for Chinese domestic projects, with documentation provided for customs clearance and regulatory compliance. Our engineering team provides full custom design services, adapting the crane to your specific span, lifting height, and capacity requirements, including modifications for unusual building constraints or integration with existing material handling systems. We guarantee a formal quotation with preliminary CAD drawings within four hours of receiving your inquiry, allowing rapid project planning. With sea freight logistics to over 60 countries worldwide, we manage international shipping from our Hefei manufacturing base, ensuring competitive freight rates and reliable delivery timelines.

The ordering process is streamlined for international buyers. Begin by contacting our sales team via WhatsApp or email with your project requirements, including capacity, span, lifting height, and preferred control type. Our engineers will respond within four hours with a detailed quotation, technical datasheet, and preliminary CAD drawing showing the crane layout in your facility. Upon acceptance, a 30% T/T deposit initiates production, with the balance due before shipment. Manufacturing lead time is 30 to 45 days depending on complexity and current production schedule. After production, we arrange sea freight to your nearest port, with optional on-site installation and commissioning services available through our local partner network. All cranes are test-run and load-tested at our factory before disassembly for shipping, with full inspection reports provided.
