Sheave Regrooving & Manufacturing

Keeping elevators in various buildings and facilities running at peak performance is important for both efficiency and safety.

Today’s industrial and commercial facilities demand a great deal from modern elevators; with movement towards decreased power consumption, reduced equipment costs, increased space utilization, and constant usage, elevators are under unbelievably high levels of scrutiny.

Due to these factors, and more aggressive sheave groove profiles, one of the keys to proper elevator maintenance is sheave regrooving. A worn sheave causes additional wear on the ropes that are at the heart of elevator operation, so they demand more maintenance than ever before. It is important to remember that all sheaves will need to be regrooved at least once during their service lives, so it is critical to have the right team supporting you.

At Renown Electric Motors and Repair Inc., one of our top specialties is elevator sheave regrooving and manufacturing. Since 1984, our dedicated elevator experts have been returning sheaves to their OEM specifications, as well as manufacturing ideally matched or upgraded replacement parts.
