JTK Mining Hoist Winch
High-Performance Mining Hoisting Solution
MODEL: JTK-1.2×1.0
Product Overview
The JTK Mining Hoist Winch is engineered for superior performance in material lifting applications within surface or underground inclined tunnels and small shafts in coal, metal, and non-metallic mines. This robust hoisting solution features a 1.2m drum diameter and 10m width, utilizing non-explosion-proof resistor speed regulation for precise control.
Key Feature: Equipped with an electro-hydraulic single drum block safety brake system that ensures maximum operational safety and reliability in demanding mining environments.

Working Principle
The hoisting mechanism is initiated when the main motor activates. Power is transmitted from the motor rotor to the high-speed shaft of the reducer via an elastic coupling. After two-stage gear transmission deceleration, the power is transferred to the main shaft device through the coupling. Continuous alternation of the motor's rotation direction enables the drum to either wind or unwind the steel cable. This facilitates the periodic upward and downward movement of the lifting container in the shaft.
Component Structure
The JTK Mining Hoist Winch comprises several precision-engineered components working in unison:
Main Shaft Assembly
Safety Brake System
Depth Indicator
Reducer
Work Brake System
Elastic Coupling
Gear Coupling
Electric Motor
Operating Environment
This non-explosion-proof winch is designed for operation in machine rooms without explosive media, under the following conditions:
Temperature Range
-5°C to 40°C
Humidity Level
≤85% (at 20±5°C)
Altitude
≤1000m Special design required above 1000m
Restrictions
No violent vibration, bumps, or corrosive gases
Important: Equipment must be protected from water and liquid penetration. When altitude exceeds 1000m, the reduction in air cooling effect and dielectric strength must be considered. Special design agreements between manufacturer and user are required for such conditions.
