Lessons and insights from elevator counterweight rope accidents
In recent years, there have been occasional incidents of elevator cabs falling due to the counterweight detaching from the suspension system as a result of serious counterweight sheave failure, leading to a loss of counterweight traction.
Unveiling the reasons behind the choice of metal materials for elevator counterweight sheaves
The core production process of MC nylon pulleys is centrifugal casting. The raw materials are mainly divided into two categories: liquid caprolactam and solid caprolactam. The quality of the raw materials has a crucial impact on the final performance of the product.
Counterweight sheave: One of the core components of an elevator system
A counterweight sheave (also known as a guide sheave or counterweight reversing sheave) is a key pulley component in an elevator system. It is mainly installed on the counterweight side or the car side to change the winding direction of the steel wire rope and adjust the traction force.
In-depth Analysis of Elevator MC Nylon Wheel Failure Causes and Prevention Suggestions
In recent years, with the continuous increase in the number of elevators, MC nylon wheels have gradually revealed some safety hazards caused by the characteristics of nylon materials during elevator operation.
Elevator regulations regarding nylon wheels
The latest regulations on nylon wheels in elevator laws and regulations are mainly embodied in the national standard GB/T 42.1-2022 "Single-cast polyamide sheaves Part 1: Elevator sheaves".
The Development History and Current Status of Elevator Nylon Wheels
The application of nylon wheels in elevators has become increasingly widespread, making them an indispensable key component in modern elevator systems. Nylon wheels, with their excellent wear resistance, noise reduction, and self-lubrication properties, significantly improve elevator operating efficiency and riding comfort.
