Frequently Asked Questions

In what situations does a force act on the elevator guide rails?
  • When the cabin is unbalanced - unevenly loaded;
  • When the load distribution changes during loading and unloading;
  • When the safety brake is engaged.
What are the factors that govern the rail size determination?
  • Cab weight
  • Cabin load
  • Console ranges
  • Cabin design and
  • suspension point
  • Rail mounting format
  • Safety brake type
What does cold drawn rail mean? Is the cold drawn rail an alternative to a hot drawn rail?

Cold drawn rail is not an alternative to hot drawn rail. All kinds of rails must first go through the stage of taking the "TE" profile shape by using the hot rolling technique of the raw steel. After this stage, the rails are divided into two according to the manufacturing method followed:

  • Cold drawn rails
  • Machined rails

Cold drawn rails, raw "TE" profiles are passed through hard metal caliber, by spinning and compression method; machined rails are produced by removing chips from the surface of raw "TE" profiles. Cold drawn rails are marked with the letter "A" in the standards; machined rails are symbolized by the letter "B". For example T90-A or T90-B.
