Mine Winch System
Operating environment: Works both underground (including high‑gas and dust explosion risk areas) and on the surface. Resists dust, water, and explosion hazards.
A core machine for moving materials and lifting people in mines. Different types fit different tough jobs.
Operating environment: Works both underground (including high‑gas and dust explosion risk areas) and on the surface. Resists dust, water, and explosion hazards.
Mine types:
Coal mines: Needs explosion‑proof certification – fits high‑gas and coal dust explosion risk areas.
Metal mines: Fits high‑dust, wet underground conditions and heavy surface work.
Typical jobs:
- Hauling: Moving mine cars, repositioning equipment, transporting roof support materials.
- Hoisting: Lifting personnel in vertical/inclined shafts, hoisting ore, lowering tunneling gear.
- Transport: Moving materials along horizontal tunnels, heavy towing on ramps.
- Mounting spots: Shaft top / pit bottom, inclined shaft hoist rooms, tunnel chambers, fixed work platforms at surface mines, return airway of coal faces.
Structure & Key Components
Modular design. Core parts:
| Component | Description |
|---|---|
| Drum System | Wraps wire rope; carries and transmits lifting load. Types: single drum, double drum, friction wheel. |
| Drive System | Reducer (planetary / helical gear), coupling, drive shaft. |
| Brake System | Disc or shoe brake, hydraulic / pneumatic power unit. |
| Power System | Explosion-proof or standard motor / hydraulic motor, control cabinet. |
| Safety System | Overwind protection, slack rope protection, load sensor, depth indicator. |
| Auxiliary Devices | Rope guide, tensioner, shuttle car (for endless rope winch), tail wheel (for endless rope winch). |
Motor drive:
Standard jobs: squirrel‑cage induction motor. Underground: flameproof type.
Supports VFD speed control. Some heavy loads use a hydraulic motor.
Reduction & braking:
Reduction: Hardened gear reducer turns high speed low torque into low speed high torque – efficiency ≥90%.
Braking: Two systems – service brake (normal stop) and emergency brake (panic stop). Hydraulic/pneumatic servo control. Auto brake on power loss – response ≤0.2 s.
Load control:
Closed‑loop system monitors rope tension in real time.
Constant‑speed hoisting / constant torque output – automatically detects load weight and adjusts parameters.
Works with depth indicator for precise travel control – prevents overwind and overrun.
Key Technical Specs (Typical Configuration)
| Parameter | Typical Range | Notes |
|---|---|---|
| Rated Load | 5–100 t (custom up to 200 t) | Graded by hoisting needs; heavy-duty >200 t |
| Rope Speed | 0.5–8 m/s (VFD stepless) | Automatically optimizes speed based on load |
| Drum Capacity | 100–1200 m (custom by shaft depth) | Multi-layer winding – saves space |
| Motor Power | 30–630 kW | High-efficiency motor – 20–40% energy saving vs traditional |
| Power Supply | 380V / 660V / 1140V three-phase AC | Underground often uses 660V / 1140V flameproof |
| Working Slope | 0–45° (inclined) / 90° (vertical) | Add anti-slip for steep slopes |
Safety & Mining Compliance
Explosion‑proof design: Flameproof motor (Exd I Mb), intrinsically safe control system – meets coal mine safety regulations.
Safety protections:
- Emergency brake: Auto‑engages on power loss – response ≤0.2 s, deceleration ≤5 m/s².
- Overload protection: Stops and alarms when load exceeds 110% of rated.
- Overwind protection: Mechanical + electronic dual limit – prevents overwind of the conveyance.
- Applicable standards: GB 20181‑2006, AQ 1035‑2007, and other mining standards.
High‑strength steel: Drum forged from Q345B or 45# steel. Frame welded thick plate – tensile strength ≥600 MPa.
Wear parts:
- Drum hard‑faced with wear‑resistant alloy. Wire rope galvanized or plastic‑coated.
- Brake shoes – high‑friction wear‑resistant material. Gear surfaces carburized and hardened.
- Industrial rating: IP54 – works in -20°C to 40°C, 95% humidity underground. Some models have CE, ATEX.
Installation, Operation & Maintenance
Installation requirements:
Must be fixed on a concrete foundation strong enough – levelness error ≤0.1‰.
Coaxiality between shaft center and drum center ≤0.5 mm. Underground installation must interface with gas monitoring.
Operation features:
Three modes: manual, automatic, remote. Visual HMI with fault diagnosis display.
For endless rope winches: works with tensioner, shuttle car, tail wheel, etc.
Routine maintenance:
Daily: Check brake shoe wear, rope tension, lubrication.
Weekly: Measure temperature and vibration of reducer and motor.
Monthly: Calibrate depth indicator and overload protection. Full disassembly every six months.
