Abstract
An elevator may include an elevator car; a traction sheave that comprises a plurality of grooves; a hoisting machine configured to drive the traction sheave; and a plurality of beltless hoisting ropes configured to interact with the traction sheave to move the elevator car. An overall contact between the traction sheave and the hoisting ropes may exceed a contact angle of 180°. A diameter of the traction sheave may be less than 320 mm. The hoisting ropes may include a load-bearing part twisted from steel wires. A thickness of the load-bearing part twisted from the steel wires may be less than 8 mm. Each of the hoisting ropes may further include an individual exterior coating.
