Gearless sheave regrooved on dynamic  balancer

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.

With extensive experience in regrooving elevator sheaves, we offer valuable technical knowledge that is compatible with new developments in elevator design and construction.

Sheave Groove Comparison - Before & After Regrooving

Our on-site service includes evaluation of sheave grooving for proper rope fit. Sheaves should be checked annually and if groove wear is seen, regrooving may be necessary. There are a number of factors that affect the need or frequency of regrooving. Different groove types wear ropes at different rates. Our experts are able to recommend the correct groove to meet requirements and optimize sheave life. Proper and correct grooving extends the life of the rope. Ensuring that there is the right groove and the right amount of traction will lead to less maintenance. Generally, regrooving is required at least once during the elevator’s service life. The frequency of this is dependent upon factors such as groove type and number of cycles.
