Rail car liner

The friction pad bears all the weight of the steel wire rope, the weight of the container, the weight of the cargo, the weight of the balance tail rope, and various dynamic and impact loads during operation. The hoist relies on the friction between the steel wire rope and the lining to transmit power. If the friction coefficient between them is too low, the hoist will slip, causing high-speed over coiling, causing the hoist steel wire rope to be pulled off, and accidents such as the hoist container falling into the bottom of the well. Given the important role of friction pads, it is required that they have sufficient compressive strength; There must be a sufficiently large friction coefficient between the steel wire rope and it to prevent sliding during the lifting process.
