General purpose overhead crane
Extreme-Heat Resistant Ladle Crane with Dual Redundant Safety for Molten Metal Handling
1. Product Overview
The Weiyuan Foundry & Metallurgy Ladle Overhead Crane is specifically engineered to safely lift and transport liquid metal in steel mills and smelting plants. Equipped with thermal radiation shielding underneath the main box girders, laminated plate hooks, redundant emergency drum brakes, and auxiliary hoists for ladle tilting, this heavy-duty bridge crane delivers safety and reliability under extreme temperatures.
2. Key Advantages & Technical Highlights
- Dual Redundant Hoisting Brakes: Dual service disc brakes plus an emergency caliper brake acting directly on the rope drum prevent load drop if mechanical transmission fails.
- Thermal Radiation Barrier: Heat-insulating shields fitted underneath the main girders protect critical electrical cabling, motors, and steel structures from radiant heat.
- High-Strength Laminated Hooks: Laminated rivet-plate lifting hooks resist thermal shock and prevent catastrophic failure compared to forged hooks.
- Dual Motor Redundancy: Hoisting mechanisms feature double-motor synchronization capable of safely lowering full ladles even if one motor fails.
