What should you check for on the counterweight sheave?

When checking the counterweight sheave, it is essential to monitor noise and heat. Excessive noise can indicate issues such as misalignment or mechanical wear, while unusual heat can suggest problems like friction or inadequate lubrication. Both conditions can lead to mechanical failure, which could compromise the hoistway system’s safety and reliability. Therefore, paying attention to these indicators is vital in ensuring the proper functioning of the sheave and, by extension, the entire elevator system.
