Elevator Hall Door Triangular Lock V30: Critical Safety Component from Nanjing Zhuye Elevatorparts
The elevator hall door triangular lock is a dedicated emergency unlocking device for elevator hall doors, designed exclusively for professional maintenance personnel to unlock hall doors during elevator failures or maintenance. It serves as a key component balancing maintenance convenience and passenger safety—preventing unauthorized opening of hall doors while enabling timely rescue of trapped passengers. The Elevator Hall Door Triangular Lock V30, exclusively supplied byNanjing Zhuye Elevatorparts, is precision-manufactured for modern passenger and freight elevators. Compliant with international standards such as EN 81-20:2014 and GB/T 7588.1—2020 (which specifies strict position and safety requirements for triangular unlocking devices) , this triangular lock features a specialized triangular key design, reliable locking mechanism, and anti-tampering structure. It is compatible with mainstream elevator brands including Schindler, OTIS, KONE, and domestic well-known brands, widely used in residential buildings, commercial complexes, airports, and subway stations.
Nanjing Zhuye Elevatorparts adheres to strict quality control standards, and the V30 elevator hall door triangular lock embodies this commitment. Each lock undergoes rigorous testing before leaving the factory, including torque testing for unlocking, corrosion resistance testing, wear resistance testing, and structural strength verification. The lock body is made of high-strength stainless steel, ensuring resistance to impact and corrosion in harsh elevator shaft environments. The triangular key is crafted from hardened alloy steel, featuring precise dimensional accuracy that ensures a perfect fit with the lock core. The internal structure adopts a cam-driven design that enables unlocking with a 90° rotation , minimizing operational effort while ensuring reliable reset. Additionally, the lock is equipped with a built-in anti-loosening mechanism to prevent accidental unlocking due to vibration, and its installation position complies with GB/T 7588.1—2020 requirements, ensuring easy access for maintenance personnel while remaining inaccessible to ordinary passengers.
Usage Guide for Elevator Hall Door Triangular Lock V30
Correct use and management of the V30 triangular lock are critical to elevator safety. Nanjing Zhuye Elevatorparts emphasizes that only professional maintenance technicians with special equipment operation certificates are permitted to use this lock. Unauthorized use may lead to serious accidents such as falls into the elevator shaft. Before use, confirm that the lock model matches the elevator hall door type and check the integrity of the lock body and key. For detailed operation procedures, safety precautions, and matching requirements, refer to the product manual provided by Nanjing Zhuye Elevatorparts or contact our technical support team for professional guidance.
1. Pre-Use Preparation
First, place a “Maintenance in Progress” warning sign at the elevator entrance to alert passengers and prevent accidental approach. Confirm the elevator’s operational status through the main controller or on-site inspection to ensure it is in a stopped state. Prepare the dedicated triangular key matching the V30 lock, along with safety equipment such as anti-slip shoes and safety belts. Inspect the V30 lock body for damage, corrosion, or jamming, and check if the triangular key is deformed or worn—replace damaged components immediately if found. Before unlocking, communicate with relevant personnel to ensure no one is inside the elevator car or near the hall door to avoid unexpected risks.
2. Correct Operation Steps
Insert the dedicated triangular key into the V30 lock hole and rotate it 90° clockwise or counterclockwise (the lock supports bidirectional unlocking ) until a clear “click” is heard, indicating the internal locking mechanism has been released. Gently pull open the hall door to a gap of approximately 10cm first , and carefully check the position of the elevator car using a flashlight—only fully open the hall door if the car is aligned with the current floor. After completing maintenance or rescue work, close the hall door firmly to ensure the lock body automatically resets. Rotate the key in the opposite direction to remove it and verify that the hall door is securely locked by pulling it lightly. Finally, remove the warning sign and restore the elevator to normal operation through the main controller.
3. Daily Management & Maintenance
Implement strict management of the V30 triangular lock keys—store them in a dedicated locked cabinet, with access records maintained to prevent loss or unauthorized use. Maintenance personnel should inspect the lock monthly: clean the lock hole and surface with a dry cloth to remove dust and debris, apply a small amount of anti-rust lubricant to the key and lock core to ensure smooth operation, and check the integrity of the anti-tampering structure. Avoid using excessive force during unlocking to prevent damage to the internal mechanism. If the lock is difficult to unlock or cannot reset automatically, stop using it immediately and contact Nanjing Zhuye Elevatorparts’ technical team for maintenance. It is strictly prohibited to modify the lock structure or use non-specialized keys, as this will compromise elevator safety.
Replacement Cycle of Elevator Hall Door Triangular Lock V30
The replacement cycle of the V30 elevator hall door triangular lock is determined by usage frequency, environmental conditions, and maintenance quality. Under normal conditions—elevator operation time of 12-24 hours daily, dry and well-ventilated elevator shaft, and regular maintenance—Nanjing Zhuye Elevatorparts recommends a replacement cycle of 8-10 years. This cycle is based on extensive field data, considering factors such as wear of the lock core, aging of internal springs, and corrosion of the lock body, which are the main factors affecting unlocking reliability and safety performance.
For elevators in high-traffic areas such as shopping malls, airports, and subways, where the triangular lock is frequently used for maintenance, or in harsh environments with high humidity, heavy dust, or corrosive gases, the replacement cycle should be shortened to 5-7 years. Frequent use and harsh environments accelerate component wear and corrosion. For low-frequency use elevators such as villa elevators, with proper maintenance, the cycle can be extended to 10-12 years. However, in accordance with TSG T7001-2023 regulations, professional technicians from Nanjing Zhuye Elevatorparts should conduct annual inspections on locks over 10 years old, focusing on testing unlocking smoothness and structural integrity.
Regardless of service life, replace the V30 triangular lock immediately if: unlocking requires excessive force or is accompanied by abnormal noises; the lock cannot reset automatically after unlocking; the lock body is cracked, severely corroded, or the key is deformed/worn and cannot be used; the lock fails anti-tampering tests; or it cannot pass annual safety inspections. Timely replacement is critical to avoid situations where maintenance personnel cannot unlock the hall door in an emergency, endangering trapped passengers’ lives, or unauthorized personnel opening the door due to lock failure.
