INTRODUCTION
What is this?
The LDY metallurgical single girder crane is a specialized overhead crane designed for high-temperature environments in metal smelting and casting facilities. It features a reinforced single main beam structure with a metallurgical-grade electric hoist equipped with heat-resistant components, secondary braking systems, and enhanced safety protections. This crane achieves precise lifting and handling of molten metal ladles, hot ingots, casting molds, and high-temperature materials. If your foundry or steel mill requires reliable lifting of hot materials up to 10 tons with limited budget or building space that cannot accommodate a double girder metallurgical crane, this product is designed for you.
Why choose a metallurgical single girder crane over a standard single girder crane for high-temperature applications?
Compared to standard single girder cranes used in high-temperature environments, the LDY metallurgical solution offers five core advantages:
First, heat-resistant design – metallurgical-grade hoist with heat shields, high-temperature lubricants, and heat-resistant cables operates safely in ambient temperatures up to +80°C.
Second, dual brake system – primary and secondary brakes provide redundancy, ensuring safe load holding even if one brake fails – a critical requirement for molten metal handling.
Third, enhanced electrical protection – all electrical components are rated for high-temperature operation with thermal overload protection and forced cooling on motors.
Fourth, reinforced structure – the single girder is reinforced with thicker steel plates and additional stiffeners to withstand thermal stress and shock loads.
Fifth, emergency lower function – manual lowering device allows controlled descent of loads in case of power failure, preventing solidification of metal in ladles.
Get metallurgical-grade safety and heat resistance with a more economical single girder structure.
What can we do for you?
We understand that every customer has different operating temperatures, different ladle capacities, and different workshop conditions. Therefore, we offer flexible customization options: lifting capacity from 1 ton to 10 tons; span from 7.5 meters to 22.5 meters; hoist types with insulation class H motors (180°C rating); control options of heat-shielded cabin or remote radio with heat-resistant housing; lifting speeds optimized for molten metal handling to prevent splashing. Whether your facility handles molten aluminum, copper, steel, or iron, we can match the most suitable heat protection level and safety configuration.
Unsure? Don't know?
Not sure whether a single girder metallurgical crane can handle your operating temperature? Don't know what safety features you need for your specific metal type? No problem. Just tell us: your maximum molten metal temperature, your ladle weight, and your workshop clearance height. Our engineers will provide you with an accurate quote and CAD drawings within 24 hours.

APPLICATION SCENARIO
[1] Foundries – Molten Metal Transfer – Lifting and transferring ladles filled with molten iron, steel, aluminum, or copper from melting furnaces to pouring stations. Heat shields protect the hoist from radiant heat. Dual brakes ensure safe holding if power fails.
[2] Steel Mills – Ingot and Casting Handling – Moving hot steel ingots from molds to soaking pits or rolling lines. Reinforced girder handles thermal expansion cycles without distortion. High-temperature cables prevent electrical failures.
[3] Heat Treatment Workshops – Lifting hot components from heat treatment furnaces to quenching tanks or cooling beds. Manual emergency lower function allows controlled descent if power fails mid-cycle.
[4] Non-Ferrous Smelting Plants – Handling molten aluminum, copper, zinc, or lead ladles. The hoist's thermal insulation class H motors (180°C rating) operate reliably in high ambient temperatures near melting furnaces.
[5] Casting Facilities – Mold Handling – Lifting and positioning heavy casting molds, risers, and pouring cups. Shock-absorbing design reduces impact damage to molds during placement. Precise speed control minimizes metal splashing during pouring.
