Overview
LDY metallurgical electric single-beam crane is designed for harsh industrial environments such as metallurgy, casting, forging, etc. with high temperature, high dust and strong impact. It combines solid structure, professional protection and reliable performance. It is the core equipment for molten metal lifting, hot workpiece transfer and heavy material handling, providing efficient, safe and stable material transportation solutions for metallurgical production processes.
Core Structure
Main beam:box structure: made of high-strength steel (such as Q345B), with stiffening ribs inside.
Preset camber: resist full load deflection and run smoothly.
High temperature resistant anti-corrosion coating: adapt to harsh environment.
End beam: rigid connection: firmly connected to the main beam by high-strength bolts or welding.
"Three-in-one" drive: integrated motor, reducer, brake, compact structure.
Double wheel design: alloy steel wheels (double rims), matching special tracks (such as QU80).
Operating mechanism: trolley operation (longitudinal): double-sided "three-in-one" drive to ensure synchronous straight driving. Trolley operation (horizontal): "three-in-one" drive, running on the lower flange track of the main beam. Buffers are set at both ends.
Lifting mechanism (core): Independent rigid bracket: fixed on the trolley frame. Metallurgical special motor: fully enclosed air cooling, H-class insulation. Hardened gear reducer: high load-bearing capacity.
Double braking system: main brake (high-speed shaft) + safety brake (low-speed shaft/reel), double protection. Reel and pulley group: cast steel material, with anti-rope device. Metallurgical hook group: forged hook, with bearings. High-temperature resistant steel wire rope: independent steel core, resistant to high-temperature extrusion.

Application
Steelmaking workshop: lifting, dumping and transfer of molten steel ladle (refining ladle, casting ladle).
Continuous casting area: lifting and replacement of ingots and tundishes.
Rolling workshop: lifting and replacement of ingots, hot-rolled coils and rollers.
Casting workshop: transportation of molten iron ladle, sand mold and castings.
Forging workshop: handling of large forging billets and dies.
Raw material yard/scrap steel processing: loading and unloading and batching of furnace materials and scrap steel.
Selection and installation suggestions
Clear working conditions: Accurately provide key information such as lifting weight, span, lifting height, working system (busyness), ambient temperature (especially distance from heat source), type of hoisted material (whether molten metal), etc.
Safety first: When hoisting molten metal (≥1t), metallurgical cranes that comply with the national special equipment safety technical specifications (such as TSG Q0002) must be selected, and ensure that they have mandatory safety configurations such as double brakes.
Professional installation: Installation, commissioning and acceptance must be carried out by qualified professional teams to ensure track installation accuracy and equipment operation performance.
Regular maintenance: Strictly implement regular inspection and maintenance systems, especially inspection of high-temperature area components (wire ropes, brakes, motor insulation, etc.).
