Steel cables

Steel cables are used in differential traction installations and are designed to support the weight of the cab and chassis. Due to the high loads to which they are subjected, they have a special configuration.

The different parts that make up the steel cable are explained below:

  1. Wire:
    It is the main component of the steel cable. It is manufactured from steel of different qualities, depending on the intended use of the final cable.
  2. Thoron:
    It is made up of a set of wires wound helically around a center.
  3. Soul:
    It is the central axis of the cable where the strands are wound. This core can be made of steel, or another material of lower resistance such as plastic.
  4. Wire:
    It is the final product that is made up of several strands wound helically around the core.

The following criteria are used for cable designation:

Cable A x BB diam. C con alma D

Where:

  • A is the number of strands
  • BB is the number of wires
  • C is the external diameter of the cable
  • D is the material of the cable core

In the second illustration you can see the section of a 6 x 19 diameter 9 cable with a fibre core, made up of a fibre core and 6 strands with 19 wires each.

  2. Hello, I would like to know how long a cable of this type lasts? In my building there is an elevator that has been disabled for more than 25 years, the counterweight has been kept at a height of 5 floors since then. It is a 6-story building that is more than 50 years old. What type of risk does this represent for the building? Is there a possibility that the cables will break? If the counterweight falls, could it cause an implosion of the building?
