Metallurgical Wire Rope Hoist | Certified Lifting Solution for Molten Metal Handling

ISO 4301/FEM 9.781 M6 Duty Certified with Dual-Brake Safety System

Brand: Henan Hengkun Crane Co., Ltd.
Applications: Steel mills, foundries, metal processing plants, and heavy industries requiring high-temperature-resistant lifting solutions for molten metal handling, casting, and forging operations.

Product Overview

Hengkun’s MH-Series Metallurgical Hoists deliver fail-safe performance for foundries, steel mills, and non-ferrous metal plants. Engineered for overhead I-beam tracks with redundant braking and thermal protection, these hoists meet stringent global standards for molten metal handling up to 100T capacity.

Critical Safety Engineering

Dual-Brake Protection System

Primary Electromagnetic Brake
- Positioned on motor shaft
- Instant engagement on power loss
Drum-Mounted Mechanical Safety Brake (Key Innovation)
- Dual-Trigger Mechanism:
  - Power interruption
  - Overspeed (≥110% rated speed)
- Positive-Locking Design:
  - Ratchet-pawl engagement on drum flange
  - Prevents free-fall during transmission failure
- Protected Failure Modes:
  - Motor seizure
  - Gearbox shaft fracture
  - Output coupling failure

Thermal Management

Heat Reflective Shields: Stainless steel shrouds on drum/hook block
Thermal Barrier Coating: Aluminized finish (800°C reflectivity)
H-Class Insulated Motors: 180°C thermal class (IEC 60034-1)
