JK Single Rope Drum Mine Hoist
- Drum diameter: 2-5 m
- Drum width: 1.5-3.5 m
- Maximum wire rope diameter: 25-62 mm
- Maximum hoisting speed: 7-14 m/s
- Application: The standard JK single rope drum mine hoist is a non-explosion-proof model, mainly suitable for surface or mine environments without explosive gases. It widely serves various mining scenarios such as coal mines, metal mines, and non-metal mines, undertaking tasks such as lifting and transporting personnel, minerals, materials, and equipment.
Introduction Of JK Single Rope Drum Mine Hoist
The JK single rope drum mine hoist, also known as the JK single-rope winding mine hoist, single-rope mining winder, single-drum mine hoist, single drum electric mine hoist, or single-cable mining elevator, is a core piece of conveying equipment in the mining industry used for vertical or inclined shaft transportation of ore, coal, personnel, and materials. “JK” represents the single-drum basic type, which is especially suitable for hoisting operations in medium and deep wells of small and medium-sized scale mines. It meets national safety standards, supports intelligent electronic control for stepless speed regulation, and can be matched to different working conditions via a frequency converter.
As a core transportation device in the upstream of the ore dressing industry chain, the JK mine hoist primarily achieves traction through the precise cooperation of a high-strength steel wire rope and a drum, adaptable to different mining scenarios such as vertical and inclined shafts. The drum diameter ranges from 2 meters to 5 meters, with a maximum lifting speed not exceeding 14 meters per second. Its core features are high load-bearing capacity, precise control, and safe and stable operation. The structural design has been optimized over a long period to ensure superior durability under complex operating conditions, making it a crucial hub connecting the underground working face and the surface production system.

JXSC also offers the 2JK model with a dual-drum design, offering higher efficiency and suitable for medium-to-deep mines with medium loads or high-yield increases. Furthermore, depending on the mine environment, a JKB explosion-proof version is available as an option to meet the needs of high-gas mines with risks of gas and coal dust explosions.
Application Scenarios
- Ore Transportation: Used for hoisting coal, metallic ores, etc., in vertical or inclined shafts, reducing the tediousness and cost of manual handling.
- Personnel Lifting: Equipped with safety devices, it can be used for miners to go up and down the mine.
- Equipment Hoisting: Can transport support materials needed for underground mining operations; assists in the transport of large machinery to underground operations.
- Waste Disposal: Transports waste from underground to the surface, reducing the impact of waste accumulation on underground production.
- Mineral Processing Integration: Works in conjunction with mineral processing equipment such as crushers, ball mills, and screening machines.
principle & structure Of JK Single Rope Drum Mine Hoist
Working Principle
The motor drives the drum to rotate via a reducer, and the wire rope wound around the drum propels the hoisting container (such as a cage or skip) up and down the shaft. The electrical control system precisely adjusts the drum’s forward and reverse rotation to achieve the container’s ascent and descent. During operation, a disc brake works in conjunction with a hydraulic station to achieve precise braking. The PLC control system collects data from the depth indicator and sensors in real time, monitoring the container’s position and operating speed. Multiple safety protection devices further ensure fully controllable operation throughout the entire process.
Structural Features
- Drum assembly: Main load-bearing component, single drum with rope grooves for anti-slip, and will not deform over long-term use.
- Braking system: Hydraulic disc brake, rapid response in emergencies, preventing overwinding or overunwinding accidents.
- Reducer: Gear transmission efficiency exceeding 95%, reducing motor speed and increasing torque.
- Coupling: Connects the motor and reducer, buffering vibration.
- Depth indicator: Real-time monitoring of the lifting container’s position.
- Electrical control system: Supports variable frequency speed control + remote monitoring, adjusting speed and starting/stopping.
