Traction Sheave Slippage Without Visible Wire Rope Wear: Where Could the Problem Be?
Traction Sheave Slippage Without Rope Wear: What’s the Cause? In elevator maintenance practice, there is a situation that often causes confusion: traction sheave slippage occurs, yet the wire ropes show no obvious wear or broken wires. Many technicians instinctively suspect rope quality and even replace the wire ropes, only to find that the problem still […]
How Much Does Traction Sheave Surface Hardening Affect Service Life?
How Surface Hardening Affects Traction Sheave Lifespan In an elevator traction system, the traction sheave does more than transmit driving force. Its surface condition directly determines wire rope wear rate, operational stability, and the overall service life of the system. When replacing traction sheaves, many people focus on dimensions and groove profiles, while overlooking one […]
What Hidden Damage Can a Mismatched Traction Sheave Groove Cause to Wire Ropes?
Hidden Wire Rope Damage Caused by Mismatched Traction Sheave Grooves In an elevator traction system, the traction sheave and wire rope are a pair of core components that rely heavily on precise matching. When abnormal wire rope wear is found, many maintenance teams focus mainly on the rope itself, while overlooking a more hidden—but far […]
When Replacing Elevator Buttons, Which Details Are Most Often Overlooked?
Commonly Overlooked Details When Replacing Elevator Buttons In elevator maintenance and modernization projects, replacing elevator buttons may seem like a “small task.” In practice, however, it is one of the most common sources of repeated rework and customer complaints. Buttons are installed, but problems such as no backlight, false triggering, abnormal signals, or even impact […]
Are Elevator Buttons with Different Voltages Interchangeable?Common Misconceptions Explained
Are Elevator Buttons with Different Voltages Interchangeable? In elevator maintenance and modernization projects, a common question often comes up: “An elevator button is just a switch—can buttons with different voltages be used interchangeably?” Especially during emergency repairs or cross-brand replacements, some technicians take a “just install it first” approach. The result, however, can be backlight […]
The Real Causes Behind Frequent False Triggering of Elevator Buttons
The Real Causes Behind Frequent False Triggering of Elevator Buttons During elevator maintenance, technicians often encounter situations such as: the elevator shows a floor call even though no one has pressed the button; or the system responds repeatedly with just a light touch or slight contact. Frequent false triggering of elevator buttons not only affects […]
What Is the Function of an Elevator Transformer?
What Is the Function of an Elevator Transformer? In an elevator control system, the elevator transformer is one of the key components that ensures the stable operation of the electrical system. It not only provides safe power to various elevator control modules but also performs voltage conversion, electrical isolation, and system protection. Whether in passenger […]
Why Should Elevators Be Equipped with Voice Announcers?
Why Should Elevators Be Equipped with Voice Announcers? With the growing trend of smart and user-friendly designs in the elevator industry, the elevator voice announcer has become an essential accessory. Whether for new installations or modernization projects, more and more building owners and property managers choose to add this device. But why is it so […]
Nice3000 Error Code E20 & PG Card
Nice3000 Error Code E20 & PG Card Fault phenomenon observed at the customer site: The main unit vibrated and triggered error E20 with subcode 03. Attempting to switch UVW had no effect, but after modifying the F3 parameter, the vibration stopped. Customer's question: Can the MCTC-PG-A2 be used on a synchronous elevator motor? Alternatively, can […]
Replacing the New INV-BDC Elevator Board Steps
Replacing the New INV-BDC Elevator Board Steps Normally, if the INV-BDC elevator board on the elevator is damaged, the high-power transistors (IGBT modules) connected to the BDC are likely damaged as well.Before installing the new BDC board, it is recommended to check the IGBT module — QM300HA-H (MVP type) or QM200HA-2H (HVP type). If the module […]
