Common Elevator Traction Sheave Models
Common Elevator Traction Sheave Models In the entire operating system of an elevator, the traction sheave is one of the most critical components in power transmission. It determines whether the elevator can run smoothly, steadily, and safely. The friction between the traction sheave and the wire rope generates traction force, enabling the car and counterweight […]
What Are the Common Brake Voltages Used in Escalators?
What Are the Common Brake Voltages Used in Escalators? In the safety mechanism of an escalator’s operating system, the escalator brake is one of the most critical safety components. Whether it is a sudden power failure, overspeed operation, chain slack, or abnormal vibration, the brake must intervene instantly to bring the escalator to a stable […]
What Are the Common Failures of Escalator Inspection Boxes?
What Are the Common Failures of Escalator Inspection Boxes? In an escalator system, the inspection box is one of the most frequently used control components by maintenance personnel. It can switch inspection modes, adjust direction, and perform low-speed debugging. It is a core tool for escalator maintenance and troubleshooting. Once the inspection box malfunctions, the […]
Common Faults Found in Elevator Door Operator Boxes
Common Faults Found in Elevator Door Operator Boxes During elevator operation, the elevator door operator box is the core component responsible for controlling the door-opening and door-closing actions. It directly affects elevator safety, stability, and passenger experience. Since the door operator system is a high-frequency operating component, various faults will inevitably occur over time. As […]
Why Is the Design of the Escalator Comb Plate So Critical to Safety?
Why Is the Design of the Escalator Comb Plate So Critical to Safety? In an automatic escalator system, people often focus on core components such as the escalator handrail belt, escalator step chain, and drive system, but tend to overlook a “most critical safety device under your feet”—the escalator comb plate. Although it looks simple, […]
Does the Material of an Elevator Landing Sill Affect the Lifespan of the Landing Door?
Does the Material of an Elevator Landing Sill Affect the Lifespan of the Landing Door? In the elevator landing door system, the elevator landing sill may look insignificant, but it is actually a key component that endures heavy friction and long-term mechanical force. Many elevator maintenance technicians and building owners often ask: “Does the material […]
What Are the Common Fault Phenomena of Elevator Modules?
What Are the Common Fault Phenomena of Elevator Modules? In modern elevator control systems, elevator modules are one of the core components of the drive system. Common modules include IGBT modules, drive modules, power modules, and inverter modules. They are responsible for speed control, drive output, and energy conversion. Once a module fails, it will […]
What Information Is Needed When Ordering or Replacing Elevator Buttons?
What Details Are Needed to Order or Replace Elevator Buttons? Elevator buttons are one of the most frequently used components in an elevator, and also the parts that are most prone to wear, damage, and aging. When buttons become unresponsive, the light does not turn on, the touch feels abnormal, or the appearance is damaged, […]
What Important Factors Should Be Considered When Replacing an Elevator Traction Sheave?
How to Replace an Elevator Traction Sheave Properly? In the elevator traction system, the traction sheave is one of the core components that drive the elevator up and down. It creates traction through friction with the wire ropes. Once the traction sheave becomes severely worn, it can cause vibration, rope slippage, inaccurate leveling, and even […]
What Safety Risks Can Escalator Main Drive Sprocket Wear Cause?
What Safety Risks Can Escalator Main Drive Sprocket Wear Cause? In an escalator system, the main drive sprocket is a core component responsible for transmitting driving force to the step chain and enabling the entire step system to run in a continuous loop. It is subjected to high torque, frequent start-stops, and continuous friction over […]
How Does the Elevator Door Lock System Prevent Accidental Door Opening?
How Does the Elevator Door Lock System Prevent Accidental Door Opening? In the elevator safety system, one of the most accident-prone scenarios is the elevator door opening by mistake when the elevator is not at the landing level. To prevent such dangerous situations, all elevators must be equipped with strictly certified door lock systems. Although […]
What Are the Benefits of Wireless Elevator Intercom Systems?
What Are the Benefits of Wireless Elevator Intercom Systems? In modern elevator systems, communication functions are an essential part of safety design. Whether passengers encounter an emergency or maintenance personnel need remote assistance, maintaining stable communication between the elevator and the outside world is crucial. With technological advancements, wireless elevator intercoms have gradually replaced traditional […]
