Sheaves

Elevator inspection and maintenance are integral to your elevator’s safety and efficiency. One of the most central components of traction elevators is their sheaves. Because elevator sheaves are imperative to an elevators’ operation, they must be inspected and maintained regularly. Failing to have your elevator’s components – specifically your elevator’s sheaves – serviced can lead to inefficient and unsafe operation. With the right knowledge, team of elevator technicians, and routine maintenance, your elevator can continue safely transporting passengers and freight at its maximum potential.

What to know about elevator sheaves

In traction elevators, elevator sheaves are the pulleys that hold the elevator cables. These are responsible for the elevator’s traction and thus its lifting motion. With continued use, the grooves in the sheaves that hold the ropes become worn and affect the elevator’s safety and efficiency. Elevator sheaves’ grooves need to properly fit the ropes so that the elevator cables have enough grip to operate correctly and safely.

Rope tension should be balanced between all ropes to reduce the stress put on the elevator’s sheaves and ropes. Having your elevator’s sheaves regularly inspected will ensure the tension is balanced and the grooves still appropriately fit the cables. It is recommended that your sheaves be inspected by a competent person. Any significant or uneven sheave wear may signal other issues your elevator is experiencing and lead to unsafe operation. Your elevator technician will either regroove your elevator sheave or recommend elevator sheave replacement.

When to have elevator sheaves replaced

Elevator sheaves that are found to not fit ropes correctly during an inspection may be able to be regrooved to restore proper rope fit. Sheave regrooving can occur on-site or in-shop, depending on the extent of maintenance they require.

It is essential to know when elevator sheave replacement is needed instead of regrooving. You will not know if your elevator is due for sheave replacement if your elevator’s sheaves are not regularly inspected. An experienced elevator technician will know whether regrooving or replacement is the best option based on your sheaves’ condition, age, and prior sheave maintenance.

Depending on the identified cause of uneven or major sheave wear, your elevator technician may also suggest other repairs or replacements be made to your elevator system. As with anything, elevator sheaves can only be repaired so many times before the inevitable need for replacement becomes imminent. Having a trusted professional elevator technician inspect your sheaves, following their advice as to whether regrooving or replacement is the appropriate course of action for your elevators, and having your sheaves repaired or replaced in a timely manner will ensure your elevator continues to operate smoothly and safely.
