JK(B)/2JK(B) Mine Hoisting Winch

En JK, JKB, 2JK, and 2JKB single-rope mine hoisting winches are suitable for the continuous and efficient transportation of materials, equipment, and personnel weighing 6 to 17 tons. They are widely used in metal and non-metal mines such as gold mines, copper mines, and iron mines. The hoists can be deployed in various scenarios, including surface industrial yards, underground inclined roadways, and medium to large vertical shafts, enabling efficient, reliable, and continuous lifting and lowering of ores, equipment, and personnel. The KB/2JKB single-rope mine hoist is specially engineered for hazardous mining environments, with spark-resistant components to prevent gas or dust ignition.

• JK: Single-drum hoist for medium-to-heavy-duty lifting operations.
• 2JK: Double-drum hoist for deeper shafts, offering balanced load distribution and improved efficiency.
• JKB: Explosion-proof single-drum hoist, suitable for hazardous mining environments with gas or dust explosion risks.
• 2JKB: Explosion-proof double-drum hoist, combining deep-shaft hoisting capacity with enhanced safety for high-risk mining conditions.

These hoists comply with stringent mining safety and performance standards, ensuring efficient, reliable, and safe material and personnel transport.

Key Features

• Advanced braking system: Features a rear-mounted hydraulic cylinder disc brake designed to provide three times the maximum static torque. It offers fast response, high safety, and a compact design.
• High-efficiency rope-tensioning mechanism: The dual-drum model is equipped with a radial-tooth hydraulic rope-tensioning clutch, enabling synchronized operation of both containers. Rope tensioning is fast and reliable, making it suitable for multi-level hoisting.
• Flexible Electrical Control System: Supports three configurations (standard electrical control, PLC control, and variable frequency drive control) to meet diverse requirements.
• Comprehensive Safety Protection: Equipped with a depth indicator (gantry-type), over-winding/overspeed protection, brake clearance protection, slack rope protection, deceleration function protection, and more, implemented with a dual-circuit redundant design.

Typical Applications

The JK series hoists are versatile, safe, and efficient, making them essential for:

• Mining operations (coal, metals, minerals)
• Personnel & machinery transport
• Deep and inclined shaft logistics
• Hazardous environments (explosion-proof JKB/2JKB models)

These systems ensure reliable, high-capacity hoisting while adhering to strict mine safety regulations worldwide.
