Product Description

The JKB Explosion-proof Mine Hoisting Winch is meticulously engineered to meet the rigorous demands of lifting operations in mining environments, particularly those with hazardous conditions such as coal dust, methane, and other flammable gases. Designed and manufactured according to industry standards like Q/HBWF003, AQ1035-2007, and GB/T20961-2007, this winch ensures compliance with safety and quality regulations.

This hoist winch operates with an electric motor that transmits power to the drum via a reducer, allowing the steel wire rope to wind and unwind, facilitating the lifting and lowering of containers. The speed regulation is controlled electrically, while the braking system utilizes both hydraulic and electrical controls for secure operation. Various position indication systems provide accurate depth monitoring, enhancing operational safety.

The explosion-proof control system includes a mining-grade explosion-proof variable frequency drive (VFD), PLC control box, operator console, explosion-proof display screen, and sensors. This system is designed for environments containing coal dust, methane, or other explosive gases, suitable for single and multi-level shafts, both single and double drum configurations. It features compact structure, excellent speed and control performance, safety, and ease of maintenance.

Advanced Features:

  1. Vector Control without Speed Sensors: Ensures a wide range of speed control with high precision, maintaining 100% rated torque output at low frequencies.
  2. AFE Energy Feedback System: Utilizes advanced feedback technology to convert regenerative energy into usable power, saving energy and enhancing braking performance.
  3. Dual-Line Control: Provides reliable emergency operation under fault conditions and ensures safety with redundant design in critical circuits.
  4. Simplified Operation: User-friendly control handle simplifies operation, reducing the intensity of repetitive and complex tasks.
  5. High Automation: Minimal maintenance reduces downtime, ensuring continuous operation.

Safety Features:

  • Overwind Protection: Activates emergency brakes if overwind is detected.
  • Overspeed Protection: Engages emergency brakes if the hoist speed exceeds the set limit.
  • Depth Indicator Failure: Triggers emergency brakes if the depth indicator fails.
  • Brake Gap Protection: Alarms if the brake gap exceeds the set value.
  • Loose Rope Protection: Automatically cuts power and alarms if the rope becomes loose.
  • Wrong Direction Protection: Activates brakes if the running direction or speed is inconsistent with the set parameters.
