The working principle of a hoist (winch) liner lies primarily in its crucial role as a barrier between the hoist drum and the wire rope. The liner, typically made of wear-resistant material, is installed on the inner surface of the hoist drum. During operation, the wire rope is wound and unwound around the drum. The liner increases friction between the drum and the wire rope, facilitating better power transmission and preventing the wire rope from slipping on the drum, ensuring stable and reliable lifting and lowering of loads.
Secondly, the liner effectively protects the drum surface, reducing direct wear from the wire rope on the drum and extending the drum's service life.
Furthermore, the liner acts as a barrier and buffer, reducing impact and vibration between the wire rope and the drum, reducing noise, and ensuring smoother hoist operation.
In summary, mine hoist linings ensure safe, efficient, and stable hoist operation by increasing friction, reducing wear, and cushioning shock. It's resistant to cracking and moisture, preventing the cracking and rotting of wood linings. It's particularly suitable for use in harsh underground mine environments, such as those subject to heavy water and strong corrosive conditions.
It's easy to install, ensuring neatly arranged wire ropes, preventing rope biting and misalignment, and significantly extending the wire rope's service life.
