Magnetic vs Photoelectric Leveling Switches in Elevators
Differences Between Magnetic Leveling Switches and Photoelectric Switches in Elevators In elevator control systems, leveling detection devices are essential for achieving precise floor stopping. Among them, two common types are magnetic leveling switches and photoelectric switches. Although both types of elevator components serve the same purpose—detecting the car position—they differ significantly in working principles, application […]
Light Curtain Installation Angle & Detection Coverage
Impact of Elevator Light Curtain Installation Angle on Detection Coverage In elevator door systems, the elevator light curtain is one of the most important safety components. It forms a detection field at the doorway using multiple infrared beams. When an obstruction is detected, the system prevents the door from closing or reopens it, effectively avoiding […]
How to Identify Wear on Escalator Handrail Surfaces
How to Identify Wear on Escalator Handrail Surfaces In escalator systems, the handrail is not only essential for passenger balance but also a key component synchronized with the equipment’s operation. Since the handrail runs at high speed and is used frequently, surface wear is inevitable. If the wear condition is not properly assessed and addressed […]
Troubleshooting Elevator Door Lock Jamming
Troubleshooting Approach for Elevator Door Lock Mechanical Jamming In elevator door systems, the door lock is one of the core safety components. The elevator can only start running when the door lock is fully engaged and sends a correct signal. Therefore, if the mechanical structure of the door lock becomes jammed, it will not only […]
The Role of Elevator Emergency Power Systems
The Role of Elevator Emergency Power Systems In modern buildings, elevators have become an essential means of vertical transportation. However, in the event of a sudden power outage, elevators may stop operating and trap passengers inside the car, creating potential safety risks. Therefore, the elevator emergency power system has become a critical elevator component for […]
Causes of Escalator Handrail Speed Desynchronization
Causes of Escalator Handrail Speed Desynchronization During escalator operation, the handrail and the steps should run at nearly the same speed. This synchronization is essential for passenger safety and riding comfort. Once a speed mismatch occurs, it not only affects user experience but may also pose potential safety risks. In actual maintenance work, handrail speed […]
Common Causes of False Triggering of Elevator Light Curtains
Common Causes of False Triggering of Elevator Light Curtains In elevator door systems, the elevator light curtain is one of the most important safety components. It uses infrared beams to detect the doorway area. Once an obstacle is detected, the system prevents the door from closing or reopens it, effectively avoiding passenger entrapment. However, in […]
Consequences of Insufficient Lubrication of Escalator Step Chains
Consequences of Insufficient Lubrication of Escalator Step Chains In an escalator operating system, the step chain plays a vital role in transmitting power and supporting the continuous circulation of steps. Because it operates under high load and high frequency, proper lubrication is essential for stable performance. Once lubrication becomes insufficient, it not only accelerates chain […]
Safety Risks of Aging Elevator Door Operator Header Assemblies
What Safety Risks Are Caused by Aging Elevator Door Operator Header Assemblies? In elevator door systems, the door operator header assembly is one of the core structures responsible for controlling door opening and closing. It typically integrates key components such as the motor, transmission mechanism, door hanger rollers, belts, and control devices. Once the header […]
Typical Symptoms of Poor Contact in Elevator Door Lock Contacts
Typical Symptoms of Poor Contact in Elevator Door Lock Contacts In elevator safety systems, the door lock device is one of the most critical components for ensuring passenger safety. The door lock contacts, as a key electrical part of this system, can directly affect elevator operation if poor contact occurs—potentially leading to shutdowns or safety […]
Causes of Escalator Step Loosening
Causes of Escalator Step Loosening In the daily operation of escalators, the stability of the step system is directly related to both equipment safety and passenger comfort. Among common issues, escalator step loosening is relatively frequent but often overlooked. If not addressed in time, it may lead to abnormal noise, vibration, and even safety risks. […]
Where Are Explosion-Proof Elevator Push Buttons Used?
What Applications Are Explosion-Proof Elevator Push Buttons Suitable For? In certain industrial environments, standard elevator equipment cannot meet safety requirements. Especially in locations where flammable gases, vapors, or dust are present, any electrical spark may pose a serious hazard. Therefore, elevators used in such environments must adopt specially designed safety components—among which explosion-proof elevator push […]
