T/XZBX 0068-2025 Elevator key component life evaluation technical specification

Scope

As a highly relied-upon vertical transportation tool in urban buildings, the safety and stability of elevators directly affect public safety and the safety of users' lives and property. With the rapid growth of the number of elevators in China, a large number of elevators that have been in operation for more than 10 years have entered the aging stage. The performance degradation of key elevator components, hidden damage, and fatigue failure have become increasingly prominent, posing serious challenges to elevator operation safety and maintenance management. At present, there are no unified technical standards for life assessment of key elevator components (such as traction steel ropes, brakes, safety clutches, speed limiters, door systems, main control boards, etc.) during the design, manufacturing, and installation stages. The monitoring of their operating status during the service life, life prediction, and scrapping assessment mostly rely on empirical judgment or simple replacement cycles, lacking scientific basis and prone to causing maintenance delays or resource waste. To standardize the basic principles, methodological paths, and assessment processes for life assessment of key elevator components, improve the level of safety management throughout the entire life cycle of elevators, and promote the transformation of elevator maintenance from regular replacement to condition evaluation and predictive maintenance, this document is formulated. The document is applicable to the assessment of the health status of key components of elevators during their service life, prediction of their remaining service life, and classification of risk levels. It can also provide evaluation basis and technical support for elevator maintenance service institutions, inspection and testing agencies, elevator manufacturing enterprises, and industry regulatory units.
