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 […]
What Is the Function of an Elevator Overspeed Governor? How Does It Protect Passenger Safety?
How Does an Elevator Overspeed Governor Protect Passengers? In the elevator safety system, there is a critical safety component that passengers cannot see but is extremely important—the elevator overspeed governor. Known as the “last safety device” of an elevator, it instantly intervenes when the elevator runs at an abnormal high speed, protecting passengers’ lives. So, […]
How Long Does an Elevator Wire Rope Typically Last Before It Needs to Be Replaced?
How Long Does an Elevator Wire Rope Typically Last Before It Needs to Be Replaced? In the elevator traction system, the elevator wire rope is one of the core components that bears the weight of the car, the counterweight, and the load. Whether the elevator can operate smoothly, steadily, and safely depends largely on the […]
Can Installing an Elevator ARD (Automatic Rescue Device) Really Save People During a Power Outage?
Can Installing an Elevator ARD (Automatic Rescue Device) Really Save People During a Power Outage? In high-rise urban buildings, elevators have become an indispensable vertical transportation tool. However, regardless of how advanced the elevator brand or system is, power outages remain one of the most unavoidable sudden situations. Many users worry: “If I encounter a […]
What Are the Common Failures of Encoders?
What Are the Common Failures of Encoders? In elevator and escalator control systems, the encoder is an important electronic component used for speed detection, position feedback, and synchronous control. It functions like the “sensor of the elevator’s brain,” responsible for telling the main control system “at what speed and in which direction the elevator is […]
How to Determine Whether an Escalator Chain Needs to Be Replaced?
How to Determine Whether an Escalator Chain Needs to Be Replaced? In an escalator system, the escalator chain is one of the core components that bears the main load and continuously drives the step system. It operates under high load, high frequency, and high friction conditions for long periods, making it one of the fastest-wearing […]
What Hitachi Elevator Button Models and Styles Are Commonly Used?
What Hitachi Elevator Button Models and Styles Are Commonly Used? In elevator parts procurement, “buttons” are always one of the most frequently used, most easily worn, and most commonly replaced components. As one of the most well-known global brands, Hitachi elevators are widely used in residential buildings, commercial complexes, hotels, and public facilities. Therefore, Hitachi […]
What Is an Elevator Deflector Sheave?
What Is an Elevator Deflector Sheave? In an elevator traction system, the elevator traction sheave is usually the most noticeable component, but in fact, there is another easily overlooked yet extremely important part — the elevator deflector sheave (Deflector Sheave / Rope Deflector Pulley). Although it does not directly drive the elevator, it affects the […]
What Is the Difference Between a Traction Sheave and a Guide Wheel?
What Is the Difference Between a Traction Sheave and a Guide Wheel? In an elevator system, both the traction sheave and the guide wheel are critical running components.Although both are “wheel-type” parts, they serve completely different purposes and have a major impact on elevator stability, safety, and ride comfort. Many clients often ask during procurement […]
