What is the main function of lubrication in running sheaves?

The main function of lubrication in running sheaves is to reduce friction. Lubrication plays a vital role in ensuring the smooth operation of sheaves in various equipment such as cranes and hoists. When sheaves operate, they encounter significant friction due to the contact between the rotating parts, which can lead to wear, overheating, and ultimately, equipment failure if not properly managed.

By applying lubricant, you create a protective layer that minimizes direct metal-to-metal contact, allowing the sheaves to rotate more freely and efficiently. This reduction in friction not only enhances the performance of the equipment but also extends the lifespan of the components involved by reducing wear and tear. Consequently, maintaining proper lubrication is essential for the safe and effective operation of hoisting systems.
