Single Drum Mining Hoist Winch
Underground: Works in vertical/inclined shafts of coal and metal mines. Needs explosion‑proof, dust‑proof, moisture‑proof design – handles high gas, high humidity, heavy dust.
Surface: For above‑ground hauling and lifting at open‑pit coal and metal mines. Requires good corrosion resistance and sandstorm resistance.
Application Scenarios & Working Conditions
The single drum mining hoist winch is a key lifting machine for mine work. It fits many different tough jobs.
Operating environment
Underground: Works in vertical/inclined shafts of coal and metal mines. Needs explosion‑proof, dust‑proof, moisture‑proof design – handles high gas, high humidity, heavy dust.
Surface: For above‑ground hauling and lifting at open‑pit coal and metal mines. Requires good corrosion resistance and sandstorm resistance.
Mine types
Coal mines: Must meet explosion‑proof standards. Used for lifting coal, rock, personnel, and materials. Some cases need gas warning interlock.
Metal mines: For heavy loads in non‑ferrous and ferrous metal mines. Stronger structure and better wear resistance – handles large‑tonnage ore and waste rock.
Typical jobs
Hauling: Dragging equipment and materials in underground tunnels, or moving heavy machinery at surface mines.
Hoisting: Lifting personnel, ore, and roof supports in vertical shafts; lifting coal or waste rock in inclined shafts.
Transport: Long‑distance material transfer with rail systems – e.g., cross‑entry transport underground, horizontal hauling at surface mines.
Mounting spots
Underground: Usually at the pit bottom, tunnel entrances, or a dedicated winch chamber.
Surface: Placed near shaft tops, crusher stations, or material transfer yards – fixed on concrete foundations.
Structure & Key Components
Modular design. Core parts:
| Component | Description |
|---|---|
| Single drum unit | Wraps wire rope; carries and transmits lifting load. Forged or welded construction. |
| Drive system | Motor + reducer – provides power. Includes VFD or multi-speed gearbox. |
| Brake system | Disc brake or hydraulic shoe brake – emergency stopping, parking, and deceleration control. |
| Control system | PLC or VFD cabinet – overload protection, travel monitoring, fault warning. |
| Auxiliary devices | Rope guide, depth indicator, overwind protection, lubrication system. |
How It Works & Operating Logic
Motor drive
Standard jobs: asynchronous motor. Heavy loads or speed control needs: VFD motor.
Some explosion‑proof winches have a flameproof motor – meets underground gas safety requirements.
Reduction & braking
Reduction: Planetary or parallel‑shaft hardened gear reducer – lowers speed, increases torque.
Braking: Hydraulic brake for normal stops. Emergency triggers the disc brake's two‑stage function – stops safely.
Load control
Real‑time monitoring of rope tension and load. PLC automatically adjusts motor power.
Works with depth indicator for precise travel control – prevents overwind and overrun.
Key Technical Specs
| Parameter | Typical Range | Notes |
|---|---|---|
| Rated load | 5–500 kN (0.5–50 t) | Graded by mining class; heavy-duty models exceed 100 t |
| Rope speed | 0.5–10 m/s | VFD control enables 0.1–12 m/s stepless speed regulation |
| Drum capacity | 50–1000 m of rope | Customized according to shaft depth; supports single or multi-layer winding |
| Motor power | 15–500 kW | Selected based on load and speed; flameproof motors require certification |
| Power supply | 380V / 660V / 1140V | Underground mines commonly use 660V or 1140V flameproof systems |
| Working slope | 0° (horizontal) to 45° (inclined) | Anti-slip devices recommended for steep inclines |
Safety & Mining Compliance
Single drum mine hoist winches must strictly follow mining safety standards.
Explosion‑proof design:
Coal mine equipment meets GB 3836.1 – flameproof motor, intrinsically safe control system.
01
Emergency braking:
Two‑stage brake – deceleration ≤5 m/s² – smooth stop under heavy loads.
02
Overload protection:
Built‑in load sensor – stops and alarms when load exceeds 110% of rated.
03
Applicable standards:
GB/T 20961‑2007, MT/T 771‑2011, and other industry standards.
04
Materials, Durability & IP Rating
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.
Industrial rating:
IP54 – works in -20°C to 40°C, 95% humidity underground. Some models have CE, ATEX.
Installation requirements
Must be fixed on a concrete foundation strong enough – levelness error ≤0.1‰.
Underground installation: leave space for ventilation and maintenance. Explosion‑proof models must interface with gas monitoring.
Operation features
Visual control panel – start/stop, speed control, emergency brake. Some models support remote control.
HMI shows lifting height, load, speed, etc. Automatic fault diagnosis with alerts.
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 and inspection every six months.
Customization & Selection Support
Load rating:
Custom from 5 kN to 500 kN (0.5–50 t) based on mine needs.
Rope length:
From 50 m to 1000 m – fits different shaft depths.
Control options:
Standard PLC, VFD control, remote monitoring – multiple schemes.
Voltage options:
380V, 660V, 1140V, 3300V – fits different power supplies.
