What Materials Are Used for Elevator COP / HOP Panels?
What Materials Are Used for Elevator COP / HOP Panels? In an elevator system, COP (Car Operating Panel) and HOP (Hall Operating Panel) are among the most frequently used and most visible components. Beyond function and structure, the choice of material directly affects durability, appearance, maintenance cost, and overall user experience. So, what are the […]
Common Elevator Overspeed Governor Failures and Replacement Precautions
Common Elevator Overspeed Governor Failures & Replacement Tips In an elevator safety system, the overspeed governor is a critical protection device that prevents car overspeed and uncontrolled descent. Once the governor detects that the elevator speed exceeds the preset limit, it triggers the safety gear to forcibly stop the car—serving as the last line of […]
How to Find Elevator Buttons That Save Money, Time, and Hassle — and Last Longer
How to Choose Cost-Effective, Long-Lasting Elevator Buttons In elevator maintenance and modernization projects, elevator buttons may seem like small components, but they are actually among the most frequently replaced and failure-prone parts. Button malfunctions, dim or dead lights, unresponsive presses, and incompatible models not only increase maintenance costs, but also repeatedly consume manpower and time. […]
How to Assess Wear of Elevator Guide Shoes and Guide Shoe Liners
How to Assess Wear of Elevator Guide Shoes and Guide Shoe Liners In an elevator operating system, elevator guide shoes and guide shoe liners are critical components that ensure smooth movement of the car and counterweight along the guide rails. Although they do not directly participate in the driving process, abnormal wear can easily lead […]
Main Causes of Abnormal Noise in Elevator Guide Shoe Rollers and Key Replacement Tips
Causes of Noise in Elevator Guide Shoe Rollers & Replacement Tips During daily elevator operation, when passengers clearly hear squeaking sounds, friction noise, or intermittent abnormal noises, the issue is often not caused by the traction machine or guide rails themselves, but by elevator car guide shoe rollers. Although guide shoe rollers are wear parts, […]
Risks of Loose Escalator Comb Plate Fixing Plates and Compliance Replacement Standards
Loose Escalator Comb Plates: Risks & Standards In escalator safety systems, the comb plate often receives the most attention, while the comb plate fixing plate—which works closely with it—is frequently overlooked. In reality, once the comb plate fixing plate becomes loose, it can not only affect normal escalator operation but may also directly lead to […]
Elevator Cabin Lighting Power Supply and COP/HOP Display Fault Diagnosis
Elevator Cabin Lighting & COP/HOP Display Fault Diagnosis In daily elevator operation, the cabin lighting power supply and COP/HOP display screens do not directly participate in the drive system, but they are essential components for passenger experience and operational information display. Once a failure occurs, it can negatively affect ride comfort and may even lead […]
How to Customize or Replace New Elevator Buttons for Old Elevators?
Replacing or Customizing Buttons for Old Elevators As a large number of elevators enter the mid-to-late stage of service life, problems such as aging buttons, poor responsiveness, outdated appearance, and incompatibility with new control systems are becoming increasingly common. Compared with replacing the entire elevator, customizing or replacing elevator buttons for old elevators is a […]
Common Faults of Permanent Magnet Synchronous Traction Machines
Common Faults of PMSM Traction Machines With the development of energy-saving and intelligent elevator technologies, Permanent Magnet Synchronous Traction Machines (PMSM) have become a standard configuration in modern elevators. Compared with traditional asynchronous traction machines, PMSMs offer higher efficiency, lower energy consumption, and quieter operation. However, during long-term operation or improper maintenance, certain typical faults […]
Traction Machine Control Methods and Types
Traction Machine Control Methods and Types In an elevator system, the traction machine is the core power unit that drives the car up and down. The control method and type of the traction machine directly determine the elevator’s running smoothness, energy consumption, and long-term reliability. With continuous technological advancements, traction machine control methods have evolved […]
The Function and Common Failure Symptoms of Escalator Drive Chain Tensioning Devices
Common Failures of Escalator Drive Chain Tensioners In an escalator drive system, the drive chain tensioning device may not be the most visible component, but it plays a vital role in ensuring overall safety, stability, and service life. Many issues such as abnormal operation, increased noise, or even emergency stops are often closely related to […]
How to Determine Wear Standards for Escalator Drive Sprockets
How to Determine Wear Standards for Escalator Drive Sprockets In an escalator drive system, the drive sprocket is a critical component that transfers power from the motor to the drive chain. Its condition directly affects the smoothness, reliability, and safety of escalator operation. Once abnormal wear occurs, minor issues may include noise and vibration, while […]
