Elevator suspension and hoisting rope arrangement - The suspension ropes from car and counterweight pass over diverters, the hoist ropes from the top of the counterweight pass over traction pulley and diverter to the its lower face

摘要

Suspension ropes (3) attached to the top of elevator car (1) pass over diverting pulleys (4) to counterweight (2), the hoisting rope attached to the counterweight is passed over traction sheave (7) down to and around diverting pulleys (8) and up to counterweight underside, where the hoisting rope is formed of synthetic materials. The hoisting ropes has a structure consisting of a number of bundles of synthetic fibres (pref. aramid fibres) positioned side by side and separated from each other all sheathed in a plastic material (pref. polyurethane) such that the rope cross section has a greater width than thickness.
