If rope slippage is not corrected, what may need to be done to the sheave?

When rope slippage occurs in a hoisting system, it indicates that the ropes are not gripping the sheave properly. This can lead to inefficient operation and potentially dangerous conditions. If slippage persists, the sheave may need to be regrooved or replaced to ensure that it can hold the ropes securely.

Regrooving the sheave involves creating new grooves or deepening existing ones to better accommodate the ropes, allowing for improved traction and reducing the risk of slippage. If the sheave is excessively worn or damaged, replacement may be necessary to restore the system to proper working order.

Simply adjusting or wrapping the sheave may provide temporary relief but won't address underlying wear or damage. Similarly, cleansing the sheave could remove debris or buildup, but it will not fix structural issues contributing to slippage. Therefore, regrooving or replacing the sheave is the most effective and long-term solution to prevent further issues related to rope slippage.
