JTP/2JTP(B) Mine Hoist
The JTP/2JTP(B) Mine Hoist is a robust lifting device designed for vertical transportation in mining operations. It is used to raise and lower personnel, equipment, and materials between the surface and underground workings. This hoist system is widely employed in coal, metal, and non-metal mines, as well as in construction and industrial applications where heavy-duty hoisting is required.
Drum Number: 1-2
Capacity: Ranges from small-scale operations to heavy-duty lifting (exact tonnage varies by model).
Application: Suitable for mine shaft hoisting, auxiliary lifting in inclined shafts, and material handling in deep excavations.
JTP/2JTP(B) Mine Hoist Overview
The JTP(B) /2JTP(B) series mine hoist is a robust and reliable piece of mining equipment designed for vertical and inclined transportation of ores, coal, personnel, and materials in coal, metal, and non-metallic mines. These winches ensure safe and efficient lifting operations while complying with strict industry safety standards.
The JTP/2JTP mine hoist is the standard model of the traditional single-drum (JTP) and double-drum (2JTP) configurations. Designed specifically for small and medium-sized mines, it offers stable mechanical performance and low maintenance costs. Equipped with a mechanical braking system, it is suitable for hoisting materials such as coal and ore under medium to low loads. With flexible installation options, it provides an economical and practical hoisting solution for mines.
The JTPB/2JTPB mine hoist (or hoisting winch) is a key piece of equipment specifically designed for hoisting mine materials and personnel, and is especially suitable for large mines with higher safety requirements or underground environments containing explosive gases. With its professional explosion-proof safety, efficient and stable lifting performance, intelligent control system, and strong environmental adaptability, it has become a reliable choice for lifting operations in large mines or high-risk underground environments.

- Explosion-proof Certification (JTPB/2JTPB):Motors and control boxes meet explosion-proof standards, suitable for gas outburst mines.
- Multiple Sensor Protection:Ten safety monitoring functions including overspeed, overwind, slack rope, and shaft breakage, in compliance with the “Coal Mine Safety Regulations”.
Advantages
JTP/2JTP(B) Mine Hoist Advantages
The JTP(B) series hoisting winch offers several core advantages, making it a preferred choice in mining operations:
✔ High-Safety Braking System – Equipped with a reliable disc brake (“P” represents), ensuring rapid response and secure stopping, meeting strict mine safety standards.
✔ Energy Efficiency & Precision Control – Supports variable frequency drive (VFD), enabling smooth acceleration/deceleration, reduced energy consumption, and precise speed regulation.
✔ Compact & Customizable Design – Available in single-drum (JTP) or double-drum (2JTP) configurations, adaptable to different mine depths and lifting demands.
✔ Durability & Low Maintenance – Robust construction with high-strength materials ensures long-term performance under harsh mining conditions with minimal downtime.
✔ Wide Applicability – Suitable for both coal and metal mines, handling ore transport, personnel lifting, and auxiliary operations efficiently.
✔ Safe Explosion-Proof Design – The JTPB model is an explosion-proof device within the JTP series specifically designed for environments with risks of methane and coal dust explosions, such as underground coal mines. It eliminates electrical ignition sources at the source, ensuring safe and reliable operation in flammable and explosive environments.
These features make the JTP(B)/2JTP(B) series a cost-effective, safe, and high-performance solution for modern mining needs.
Structures & Working Principle
JTP Mine Hoist Structure
- Main Spindle Assembly: Includes an integral or split drum, main shaft, hub, and brake disc. The drum is welded from high-strength steel plate with a rope groove and plastic or wooden lining to ensure neat rope arrangement and resistance to deformation.
- Reducer: Mostly a two-stage gear reducer (parallel shaft or planetary gear), providing high input speed and low output speed with high torque. Some models support gear replacement to extend service life.
- Electric Motor: Optional ordinary wound-rotor or explosion-proof (JTPB) type, compatible with non-explosion-proof or explosion-proof electrical control systems.
- Hydraulic Disc Brake: Employs a rear-mounted cylinder design to prevent oil contamination of the brake disc; disc spring assembly provides braking force, and hydraulic release achieves both working and safety braking.
- Hydraulic Power Station: Provides stable pressure oil and features proportional pressure regulation, two-stage braking, and dual-pump redundancy to ensure braking reliability.
- Depth Indicator: A gate-style or digital indicator that shows the container position and is equipped with overwind protection and deceleration signal triggering functions. Couplings: Including flexible pin couplings and gear couplings, used for shock absorption and misalignment compensation.
- Control Panel and Electrical Control System: Supports resistance speed regulation, frequency conversion speed regulation, or PLC control, and features intelligent functions such as automatic/semi-automatic operation, fault diagnosis, and network interface.
- Double Drum Structure (2JTP/B only): Equipped with a rope-adjusting clutch (manual or hydraulic gear type) to allow independent rope adjustment for both drums, accommodating different wire rope lengths.
JTP(B) Mine Hoist Working Principle
When the motor starts, its rotation transmits power through the low-speed coupling to the high-speed shaft of the reducer. After two stages of gear reduction, the driven shaft delivers the adjusted speed and torque to the main shaft assembly via the gear coupling. By reversing the motor’s rotation, the wire rope can be wound onto or released from the drum, enabling the periodic upward and downward motion of the conveyance (e.g., cage or skip) in the mine shaft.
