What Causes Escalator Handrail Curve Noise or Jamming?
What Causes Escalator Handrail Curve Noise or Jamming? In an escalator system, the Escalator Handrail Curve device (also known as the escalator handrail inlet or handrail entrance guide) is the first safety area passengers contact when entering the escalator. It is an important part of the escalator handrail entrance system. It not only guides the escalator handrail […]
Elevator Steel Belt Pulley Wear & Belt Life Issues
Why Does Elevator Steel Belt Pulley Wear Shorten Steel Belt Life? In elevator systems using steel belt drive technology, the elevator Steel Belt Pulley is an important component for power transmission. It transfers motor power to the elevator car and counterweight through friction and engagement with the elevator steel belt, making it a key part of the […]
Escalator Drive Sprocket Wear Issues
Why Does Escalator Drive Sprocket Wear Cause Abnormal Step Operation? In an escalator drive system, the escalator drive sprocket is an important power transmission component. It transfers driving force to the escalator step chain, allowing the steps to circulate smoothly. As a key mechanical part of the escalator transmission system, the sprocket is continuously exposed […]
Why Does Elevator Light Curtain Fail?
What Causes Elevator Light Curtain False Activation or Failure? In modern elevator door systems, the elevator light curtain is one of the most important elevator door protection devices. It uses infrared signals to detect whether passengers or objects are present in the elevator door area. When an obstruction is detected, the light curtain sends a […]
Risks of Worn Elevator Buffers
What Safety Risks Can Be Caused by Elevator Buffer Performance Degradation? Elevator operation safety depends not only on the control system and drive system but also on the safety protection devices installed in the pit area. Among them, the elevator buffer is an important elevator safety component designed to absorb impact energy when the elevator […]
Why Is the Escalator Braking Distance Abnormal?
Why Is the Escalator Braking Distance Abnormal? During escalator operation, the escalator brake is a critical safety device that ensures safe stopping of the equipment. When an escalator experiences power failure, emergency stop activation, or safety protection action, the escalator braking system must stop the equipment quickly and steadily within the specified distance. If the […]
Why Does Elevator Guide Roller Wear Cause Car Vibration?
Why Does Elevator Guide Roller Wear Cause Car Vibration? In the elevator operating system, the elevator guide roller is an important moving component that connects the elevator car and guide rails. Its main function is to maintain stable car movement direction during elevator travel and reduce friction and vibration between the guide rollers and rails. […]
What Problems Can Elevator Button Contact Wear Cause?
What Problems Can Elevator Button Contact Wear Cause? In the elevator operation system, elevator buttons are important components that allow passengers to interact with the control system. The elevator button contacts inside the button generate electrical signals. When a passenger presses the button, the contacts close and transmit the floor command to the elevator control […]
Why Elevator Traction Machine Vibration Increases
Why Does Elevator Traction Machine Vibration Become Increasingly Noticeable? The elevator traction machine is the core driving equipment of the elevator system. Its operating condition directly affects the overall smoothness, riding comfort, and safety of the elevator. During actual elevator maintenance, many systems experience gradually increasing traction machine vibration, higher machine room noise, or slight […]
