Maintenance and Management of the Sky Wheel Device

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.


To ensure the safe and reliable operation of the overhead sheave assembly, its maintenance and management should be strengthened. Specific measures are as follows:

1. Strengthen lubrication management

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.

2. Regular inspection and adjustment

Regularly inspect all components of the sheave assembly, including bushings, bearings, liners, bolts, and others, to promptly identify and address any potential faults.

Regularly check the tension of the steel wire rope and promptly adjust any imbalanced tensions to ensure even stress distribution across the rope.

Regularly check the horizontal and vertical alignment of the sheave assembly to ensure that it is installed in the correct position.

3. Strengthen safety management

Develop and refine comprehensive safety management systems and operating procedures to ensure the safe operation of the sheave assembly. Provide safety education and training for operators to enhance their safety awareness and operational skills.

4. Optimized Design and Manufacturing

When designing and manufacturing pulley systems, full consideration should be given to their operating environment and service conditions. The structural design of the pulley system should be optimized to enhance its load-bearing capacity and fatigue resistance. Manufacturing quality control for pulley systems should be strengthened to ensure that all performance indicators meet the required standards.

5. Strengthen emergency response.

Develop comprehensive emergency response plans and handling procedures to ensure that, in the event of a failure in the overhead crane system, the issue can be addressed swiftly and effectively. Conduct regular drills and training sessions on the emergency response plans to enhance operators’ emergency response capabilities and safety awareness.

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.
