ELEVATOR ROPES

Following points are important in elevator ropes:

8x19S FC - 8x19S IWRC - 8x25F FC (8x19F) - 8x25F IWRC (8x19F) - 8x19W FC - 8x19W IWRC

 

• Resistance to fatigue.

• Resistance to abrasion,

• Lack of nerve.

• Appropriate preform characteristics.

​

Rope Compositions

Generally the ropes of Seale,Warrington or Filler compositions with same step parallel wires and fiber cores are preferred for this purpose. Primary rope compositions are 8x19 Seale, 8x19 Warrington or 8x19 Filler. Ropes of 6x19 Seale, 6x19 Filler compositions are sometimes preferable. 

​

General Characteristics

The ropes are elastic and with thick external wires. Resistance to Abrasion conditions are good. Choosing ropes in elevators carrying humans with at least 12 safety coefficient is advisable. Minimum breaking resistance may be 140,160 or 180 kg/mm2. Wires having two strength characteristics may be used in special elevator ropes. Ropes must be lubricated. They must be checked up frequently in use and controls made be recorded. 

​

Places of Use

They are used in every kind of elevators.
