What this video shows
When the grooves in an elevator sheave wear, they need to be machined to keep the cables running with equal tension. If the grooves are uneven in depth, the cables wear faster in the deeper ones, and that can eventually force a full sheave replacement.
In this video we cut down the higher spots so all the grooves are even. With the grooves machined, the sheave can stay in service for many more years, as long as it's properly maintained.
IRM does elevator sheave regrooving on site in the machine room, or in our shop when the sheave can come out. Most of the work is around Chicago, in skyscrapers, hotels, hospitals, schools and residential buildings, with emergency jobs in other states. Passenger and freight.
Signs a sheave needs regrooving
- New ropes wearing out ahead of schedule
- Noise, vibration, or jerky travel that adjusting the ropes doesn't fix
- Rope tension that won't equalize
- Ridges, steps, or uneven depth you can see in the grooves
