Engineering Excellence: Design & Material Innovation

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: Heat-treated, 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 (PLC) Option: Smart monitoring of lifting load, temperature, brake condition, and usage cycles. Enables predictive maintenance and minimizes downtime.
