Derived Questions

How do I compare quotations for elevator traction systems?
Use identical load, speed, roping and supply scope. Check whether brake, encoder, supports and installation accessories are included.

How do I select a traction system for elevator modernization?
Start with load, speed, travel, roping and installation constraints. Review the retained car, counterweight and electrical equipment as part of the selection.

How does counterweight selection affect a lift traction system?
The counterweight is part of the balance and traction calculation. Its required mass must be checked against car mass and the design load.

What should be checked when a traction elevator vibrates under load?
Inspect operating conditions, mechanical alignment, feedback control and suspension condition. The fault may involve more than the traction machine itself.

Can a new traction sheave be fitted while retaining existing ropes?
Assess rope condition and the proposed groove compatibility together. Follow the relevant replacement criteria for the complete rope and sheave combination.

Why do elevator suspension ropes slip on the traction sheave?
Rope and groove condition, tension distribution or system balance may contribute. Have the complete traction arrangement assessed rather than changing rope treatment.
