Effects of Escalator Step Chain Elongation
Why Does Escalator Step Chain Elongation Cause Operating Impact? During escalator operation, the escalator step chain plays a critical role in circulating the steps and transmitting power, making it one of the core components of the escalator drive system. After long-term operation, wear between chain components gradually increases the clearance between links, resulting in escalator […]
Elevator Traction Sheave Wear: Causes & Risks
Why Does Elevator Traction Sheave Groove Wear Affect Operating Safety? During elevator operation, the elevator traction sheave is a key component of the traction system responsible for transmitting driving force. The elevator car moves up and down through the friction between the traction sheave grooves and the elevator wire ropes. After long-term operation, wear of […]
Risks of Escalator Step Deformation
What Operating Risks Can Be Caused by Escalator Step Deformation? Escalator steps are critical load-bearing components that carry passengers during escalator operation. They are continuously subjected to passenger weight, operating impacts, and repeated cyclic loads. If an escalator step becomes deformed, it can not only reduce ride comfort but also cause abnormal step operation and […]
Elevator Wire Rope Wear & Diameter Changes
What Risks Can Elevator Wire Rope Wear or Diameter Changes Cause? During elevator operation, the elevator wire rope is a critical load-bearing component connecting the car, counterweight, and traction system. Its condition directly affects elevator safety and ride comfort. Over time, elevator traction ropes are continuously subjected to tension, bending, friction, and repeated cyclic loads, […]
Escalator Step Chain Tensioner Problems
What Operating Problems Can Be Caused by Escalator Step Chain Tensioner Failure? During long-term escalator operation, the escalator step chain tensioning device plays an important role in maintaining proper chain tension and ensuring smooth step movement. If the tensioning device fails, the escalator step chain may become loose, fluctuate, or experience uneven loading, which can […]
Risks of Worn Escalator Entrance Brushes
What Safety Problems Can Escalator Entrance Brush Wear or Detachment Cause? The entrance area of an escalator is an important access point for passengers and one of the areas where safety risks are concentrated. Although the escalator entrance brush is a small wear part, it plays an important role in preventing passengers’ shoes, clothing, and […]
Why Is Elevator Leveling Inaccurate? Causes and Solutions
During elevator operation, if the car stops above or below the floor level, creating a noticeable step between the elevator floor and the landing when the doors open, the elevator may be experiencing leveling accuracy problems. Elevator leveling accuracy affects not only passenger comfort but also passenger safety. The elevator leveling system mainly relies on […]
Handrail Misalignment Caused by Guide Wheel Wear
Why Does Escalator Handrail Guide Wheel Wear Cause Handrail Misalignment? During long-term escalator operation, escalator handrail misalignment is a relatively common problem. Many maintenance projects focus only on the handrail itself while overlooking the escalator handrail guide wheels, which provide essential guidance and support. In fact, worn guide wheels can directly affect the running path […]
Risks of Worn Elevator Governor Tension Pulleys
What Safety Risks Can Elevator Governor Tension Pulley Wear Cause? In an elevator safety protection system, the elevator governor plays an important role in monitoring the operating speed of the elevator car, while the elevator governor tension pulley maintains the proper tension of the governor rope to ensure that the governor can accurately transmit the […]
Why Elevator Buttons Stick or Return Slowly
Why Does an Elevator Button Return Slowly or Get Stuck After Being Pressed? In daily elevator operation, elevator push buttons are important components that allow passengers to interact with the elevator control system. If a button does not return normally after being pressed, returns slowly, or becomes completely stuck, it can affect the passenger experience […]
Escalator Step Sprocket Wear Issues
Why Does Escalator Step Sprocket Wear Cause Unstable Step Operation? During long-term escalator operation, the step system relies on precise engagement between the escalator step sprocket and the escalator step chain to maintain smooth and stable circulation. Once the step sprocket becomes worn, its tooth profile changes, or the engagement clearance becomes abnormal, the steps […]
Problems Caused by Elevator Compensation Chain Wear
What Operating Problems Can Be Caused by Elevator Compensation Chain Wear or Aging? During the operation of high-speed and high-rise elevators, the weight difference between the elevator car and counterweight changes continuously, affecting the balance of the traction system. To reduce the impact caused by changes in rope weight, elevators are usually equipped with an […]
