KJA Senior Consultant Fartash Razmjoo has a detailed technical article published in the February 2021 elevator industry magazine Elevator World.  The article provides a detailed overview of installation and maintenance requirements for elevator ropes to ensure maximum life.  Please download your copy of the article below.

Many in the industry may have noticed that an excessive number of elevators have had their ropes replaced or scheduled for replacement much sooner than in the past. Hoist rope problems have become some of the most significant maintenance concerns for both elevator contractors and building owners. Rope replacement is expensive, increases the cost of maintenance and interrupts the normal operation of the building for days and even weeks.
Elevator manufacturers claim that the quality of the ropes is not as good as it used to be. On the other hand, hoist rope manufacturers claim that not only has the quality not decreased, it is better because of modern manufacturing technologies and tighter jurisdictions and standards. Rope manufacturers believe that the new elevator designs, with their smaller machines, rope sizes and more aggressive sheave designs, put more tension on the hoist ropes, and this eventually reduces the ropes’ lifespan.
