Weihua’s metallurgical electric hoists are the result of decades of R&D and practical experience, especially in cooperation with large iron and steel enterprises. Key design innovations include:
1. Heat Shielding System: Multi-layer insulation system to protect electrical and mechanical components from radiant heat. The wire rope drum, hook block, and motor housing are thermally shielded with refractory materials.
2. Class H or Higher Insulation Motors: Motors with H-class insulation (up to 180°C tolerance), and optional water-cooled or forced-air cooling design for continuous duty.
3. Special Alloy Wire Rope: 热处理, corrosion-resistant wire ropes extend working life in high-temperature conditions.
4. Sealed Gearboxes and Bearings: Fully enclosed IP55–IP65 grade gearboxes and self-lubricated bearings extend lifespan and minimize maintenance even in dusty and humid plant conditions.
5. Programmable Logic Controller (可编程逻辑控制器) Option: Smart monitoring of lifting load, 温度, brake condition, and usage cycles. Enables predictive maintenance and minimizes downtime.
Weihua delivered 12 sets of 10T metallurgical hoists to POSCO’s slab caster line. These hoists run at 95% duty cycle with thermal monitoring systems integrated into the plant’s MES (Manufacturing Execution System).
Weihua provided customized electric hoists with corrosion-resistant coatings and spark-proof components, essential for handling molten alloys and ore concentrates in a gold purification furnace environment.
Compact design 7.5T 低净空环链电动葫芦 with trolleys enabled efficient operation under tight workshop constraints.
