Compact Mining Winch For Confined Mine Spaces
Surface: Suitable for small open-pit mines, quarries, and tunnel construction sites can be set up in limited working areas.
Application Scenarios & Working Condition Fit
Designed for tight spaces in mines, with high space efficiency and strong environmental adaptability.
Operating Environment
Underground: Works in narrow roadways, small chambers, and tunnel faces of coal and metal mines. Resists dust, water, and explosion hazards.
Surface: Suitable for small open-pit mines, quarries, and tunnel construction sites can be set up in limited working areas.
Mine Types
Coal mines: Needs explosion-proof certification. Used for material transport in narrow roadways of high-gas mines.
Metal mines: Covers non-ferrous and ferrous metal mines. Works with small shafts and inclined hoisting.
Typical Jobs
Hauling: Moving mine cars, repositioning equipment, transporting roof support materials.
Hoisting: Personnel transport in small vertical/inclined shafts, ore lifting, lowering excavation gear.
Transport: Moving materials along horizontal tunnels, heavy towing on ramps.
Mounting Locations
Underground: Tunnel chambers, tunnel ends, bottom of small vertical shafts.
Surface: Tight quarry areas, tunnel portals, fixed work platforms at small mining sites.
Structure & Key Components
Compact mining winch with modular design – core functions highly integrated.
Base frame: Lightweight but strong, made of box or tube steel.
Core units:
Drum system
Single or double drum (optional), with rope guide and rope anchor.
01
Drive system
Reducer (planetary/helical gear), coupling, drive shaft.
02
Brake system
Disc or shoe brake, hydraulic/pneumatic power unit.
03
Power system
Explosion-proof or standard motor, control cabinet.
04
Safety system
Overwind protection, slack rope protection, load sensor.
05
Load control :
- Closed-loop control monitors rope tension in real time.
- Constant-speed hoisting and constant torque output.
- Automatically detects load weight and adjusts running parameters.
Motor drive
Squirrel-cage induction motor – flameproof type for underground use. Supports VFD speed control.
Reduction & braking
Reduction : Hardened gear reducer changes high speed low torque to low speed high torque.
Braking : Two independent systems – service brake (normal stop) and emergency brake. Hydraulic/pneumatic servo control.
