Elevator systems usually include a car and a counterweight (CW) which are suspended by tension members. A hoisting motor drives the tension members to lift the car to the desired levels within a hoistway .
1.steel ropes and steel belts are bouth used.
2.steel belts have a plurality of steel rope encased in a polyurethane jacket.
3.The usage of coated steel belts has several merits, such as high abrasion resistance, good flexibility and maintainability, long lifespan, low space occupation, and low noise.
【How to use steel wire rope & steel belt】
When running over the traction sheave and the deflection sheaves, the wires in the ropes are exposed to a high complex of stress factors comprising tension, flexural stress, torsion and compression — which all lead to material fatigue. During flexural stress, the wires bend in relation to each other. The friction created between the wires results in additional abrasive wear.
So you need regular inspection permits the correct time for changing the rope to be determined or the remaining service life to be estimated.
The elevator belt lies at the heart of optimal and safe bulk processing, when running, the belt is subjected to various loads. Choosing a good quality elevator belt is crucial.
【Steel Wire Rope Structure】
When running over the sheave, all components — strand against strand and wire against wire — are in continuous movement.
Steel wires for elevators have nominal tensile strengths of 1370, 1570 and 1770 N/mm2. Higher strength levels of up to 2500 N/mm2 are possible with special approval. A steel wire achieves these extremely high strength levels by a process of manufacture which combines forming with heat treatment.
