Technical Features and Maintenance Management of Mine Hoists
Release time :
07 Nov,2025
Source:
Mine hoists are primarily used in mines to lift and lower personnel, materials, and equipment. They can transport heavy loads quickly and steadily in the vertical direction, significantly improving the efficiency of coal mining operations.
Technical features of the winch
1. A powerful propulsion system
Mine hoists are typically equipped with high-power motors that can provide sufficient power to lift heavy loads. At the same time, advanced transmission systems ensure efficient power transmission and minimize energy losses.
2. Precise control system
Modern mine hoists are equipped with advanced electronic control systems that enable precise control over lifting speed, position, and load. This not only enhances operational efficiency but also effectively prevents dangerous situations such as overloading and overspeeding.
3. Safe and reliable braking system
Mine hoists are typically equipped with multiple braking systems, such as mechanical brakes and electrical brakes, to ensure rapid stopping in emergency situations and to safeguard the safety of personnel and equipment.
4. Robust and durable structural design
Mine hoists are typically made of high-strength steel, enabling them to withstand enormous loads and impact forces. At the same time, their excellent sealing performance prevents dust, moisture, and other contaminants from entering the equipment interior, thereby extending the equipment's service life.
Maintenance and Management of Winches
1. Daily inspection
Inspect the winch daily, including the operational status of components such as the motor, transmission system, braking system, and steel wire rope. Identify and address potential issues promptly.
2. Regular maintenance
Perform comprehensive maintenance on the winch at prescribed intervals, including cleaning, lubrication, adjustment, and replacement of wear parts.
3. Safety Training
Conduct safety training for operators to familiarize them with the operating procedures and safety precautions for winches. Operators must possess the requisite qualifications and skills, strictly adhere to the operating procedures, and ensure the safe operation of the equipment.
4. Emergency Plan
Develop a comprehensive emergency response plan that covers all aspects of incident reporting, rescue operations, and handling procedures, ensuring that incidents can be addressed swiftly and effectively when they occur.

Select an appropriate grease, such as lithium-based grease No. 2 or No. 3, and ensure that the grease is clean and applied in the correct amount. Regularly inspect the cleanliness and lubrication performance of the grease, and promptly replace any grease that has deteriorated.
Common Problems and Solutions for Hoist Sheave Units
The head sheave assembly of a multi-rope friction hoist mainly consists of the head sheave shaft, fixed sheave, traveling sheave, bearing bushing, bearing housing, main bearing, head sheave lining, and retaining clips.
The Importance of Mine Hoisting Equipment
Mine hoisting equipment serves as an essential link between the underground and surface of a mine. In underground mining operations, large quantities of ore, waste rock, and other materials need to be hoisted to the surface for processing; at the same time, miners rely on this hoisting equipment to safely travel back and forth between the underground and the surface.
