Increasing demands on elevator use, as is common in most modern buildings, leads to increasing wear on the equipment. We provide a solution and service to keep elevators in best working condition.

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.
