Remote Control Mining Winch For Mine Haulage
Surface: Works in open‑pit mines with extreme heat, cold, sandstorms, etc.
Application Scenarios & Working Conditions
Operating environment
Underground: Fits high‑gas, high‑dust, wet tunnels in coal and metal mines. Needs explosion‑proof and dust‑proof design.
Surface: Works in open‑pit mines with extreme heat, cold, sandstorms, etc.
Mine types
Coal mines: Meets explosion‑proof safety standards – suitable for working faces and tunnel haulage.
Metal mines: Covers ferrous and non‑ferrous metal mines – for ramp transport and vertical shaft hoisting.
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.
Structure & Key Components
Base load‑bearing structure: One‑piece welded high‑strength frame, box‑beam design.
| Component / System | Description |
|---|---|
| Base Load-Bearing Structure | One-piece welded high-strength frame, box-beam design. |
| Drum System | Multi-layer winding drum (with rope guide), rope anchor. |
| 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, control cabinet. |
| Safety System | Overwind protection, slack rope protection, load sensor. |
| Remote Control System | Wireless remote controller, signal receiver, antenna, signal amplifier. |
Remote control operation:
- Remote controller sends commands (start, stop, speed change, direction change, etc.).
- Receiver picks up the signal and sends it to the electrical control system.
- Control system then runs the motor, brake, and other actuators.
- Signal encryption and anti‑interference design – ensures safe, reliable command transmission.
Motor drive:
Squirrel‑cage induction motor – flameproof type for underground use. Supports VFD speed control.
Reduction & braking:
Reduction: Hardened gear reducer turns high speed low torque into low speed high torque.
Braking: Two systems – service brake (normal stop) and emergency brake (panic stop). Hydraulic/pneumatic servo control.
Load control:
Closed‑loop system monitors rope tension in real time.
Constant‑speed hoisting / constant torque output.
Automatically detects load weight and adjusts operating parameters.

| Motor Power | 37–500 kW |
| Power Supply | 380V / 660V / 1140V three-phase AC |
| Working Slope | 0–45° (inclined shaft) / 90° (vertical shaft) |
| Remote Control Range | 100–500 m (underground vs surface different) |
| Signal Frequency | 433 MHz / 868 MHz (industrial bands) |
Explosion‑proof design: Flameproof motor, intrinsically safe control system – meets coal mine safety regulations.
Safety protections:
- Emergency brake: Automatically engages within ≤0.2 s on power loss.
- Overload protection: Stops automatically when load exceeds rated by 15%.
- Overwind protection: Mechanical + electronic dual limit.
- Remote control safety: Remote has an emergency stop button, low battery alarm, and signal loss protection.
Main structure: Q355B high‑strength steel, welded and stress‑relieved by annealing.
Wear parts:
Drum surface induction hardened – hardness ≥HRC45.
Wire rope galvanized or plastic‑coated – breaking force ≥1.5× rated load.
Gear surfaces carburized and hardened – hardness ≥HRC58.
Environmental protection: IP55 – works from -20°C to +40°C, 95% humidity.
Remote control parts: Remote controller has IP65 – stands up to tough mine conditions.
Installation, Operation & Maintenance
Installation requirements:
Must be mounted on a poured concrete foundation – levelness error ≤0.1‰.
Coaxiality between shaft center and drum center ≤0.5 mm.
Remote signal receiver must be placed in a good signal area – avoid obstructions.
Operation features:
Three modes: manual, automatic, remote.
Visual HMI with fault diagnosis display.
Remote controller is easy to use – has anti‑mistake design.
Routine maintenance:
Change reducer oil every 6 months.
Replace brake shoes when wear exceeds 1/3 of thickness.
Lubricate wire rope monthly; check wear regularly.
Replace remote batteries regularly; test signal system periodically.
