Keep Elevators Running at Peak Performance for 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.
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.

Ensure Cables Have Enough Grip on the Sheave to Operate Effectively
As ropes and drive sheaves age, sheave regrooving is a common repair. With extensive experience in regrooving elevator sheaves, we offer valuable technical knowledge that is compatible with new developments in elevator design and construction. At Renown Electric, we have capabilities suitable for all makes and models of elevators.
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.
Complement Your Sheave Regrooving Service with the Vertima Balance Hydraulic Rope Equalizer
After investing in sheave regrooving to ensure optimal rope-to-groove interface, the next logical step to maximize your elevator system’s efficiency and longevity is to ensure perfectly uniform rope tension. Unequal rope tension is a leading cause of premature rope and sheave wear, rapidly undoing the benefits of your regrooving service.
We highly recommend installing the Vertima Balance Hydraulic Rope Equalizer as a permanent, maintenance-free add-on during re-installation. This advanced German-engineered device is designed to eliminate all issues associated with unequal rope length in your system, delivering unmatched precision and protection.
Key Features and Benefits
The Vertima Balance provides a host of advantages that secure your investment in regrooving and improve overall elevator performance:
- Maximize Rope and Sheave Life: By ensuring all ropes bear an equal load, the Vertima Balance minimizes abrasion on your newly regrooved traction sheave or pulley. This can lead to a rope service life up to 50% longer, significantly cutting replacement costs.
- Maintenance-Free and Auto-Remediating: This device operates within a closed hydraulic system, requiring no routine or preventative maintenance. It features real-time detection and immediate remediation for inconsistent rope tension, eliminating the need for time-consuming tension inspections or manual configuration settings.
- Superior Ride Comfort and Performance: The equal dispersion of cable tension results in a much smoother, quieter ride for users, with less bucking, reduced shearing, and improved stopping accuracy at the holding position.
- Flexible and Fast Installation: The unit typically ships fully assembled and is ready to install. It can be mounted in nearly any position (on the cabin, in the machine room, or upside-down in the machine room for 2:1 applications) and integrates seamlessly with existing equipment, making for a quick and easy service addition.
Protect your newly regrooved sheaves and secure the longevity of your ropes by incorporating the Vertima Balance into your modernization or repair project.
