Understanding Traction Hoist Ropes in Today's Elevator Installations $$$$ Continuing Discussion on Perceptions of What Might Be Wrong with the Ropes

摘要

After reading this article, you should have learned about: 1. Factors that can adversely affect hoist-rope life 2. Why lubricating and tensioning hoist ropes are necessary processes 3. As elevator machines age, hoist-rope life expectancy goes down and why Over recent years, industry professionals have begun to acknowledge that increased reports of elevator breakdowns connected to rope wear or rope failure are more than a simple sign of inherent rope manufacturing or design deficiencies. Many are now coming to see hoist rope "failure" as the result of a combination of factors that more properly have their source in the initial installation phase of a project or are points that are overlooked during routine maintenance. Indeed, many professionals are also even coming to the opinion that a key contributing cause behind "early" hoist rope failure is potentially related to some industry calculations that do not consider how newer, faster accelerating and decelerating elevators are placing far greater strains on older, long-established rope selections (such as standard 8 × 19 sisal varieties) - strains that those ropes were not originally created to handle.
