Applications

The Explosion-Proof Wire Rope Hoist is designed for hazardous environments where safety is paramount. When there are flammable gases or explosive mixture of vapour and air as shown in the below table (table 1), the explosion-proof electric hoists can be installed on I-beam for lifting and for reciprocating liner or curvilinear movements in a safe manner.

  • Petrochemical Industry:
    Lifting tasks in refineries and chemical plants.
  • Gas and Oil Industry:
    Ideal for offshore platforms and processing units.
  • Manufacturing:
    Safe handling of flammable materials in factories.
  • Mining:
    Operations in areas with underground explosive gases.

This hoist is suitable for both Type I and Type II environments, with specific applications including coal mines (Type I) and other hazardous industrial settings (Type II).

Advanced Safety Features

  1. Overload Protection
    Prevents the hoist from operating beyond its rated capacity, ensuring operator and equipment safety.

  2. Fire Stopper Limit Device
    Explosion-proof limit devices safeguard against over-lifting or lowering.

  3. Emergency Stop System
    A manual cutoff mechanism halts operations during critical conditions.

  4. Explosion-Proof Electrical Components

    • Explosion-proof electric control box and control board.
    • All wiring is insulated and grounded for enhanced safety.

  5. Non-Spark Design

    • Hooks and stop blocks are constructed with stainless steel or bronze.
    • Gear reducers are lubricated with machine oil to prevent high-temperature sparks.

  6. Temperature and Voltage Tolerance
    Operates reliably within a wide temperature range and withstands power fluctuations.

Main Components and Design

1. Lifting Mechanism

  • Explosion-Proof Motor:
    Fully enclosed tapered rotor asynchronous motor with IP44/IP54 protection.
  • Reducer:
    Cylindrical gear reducer with anti-friction bearings for smooth, efficient operation.

2. Hook Assembly
