Elevator Door Triangle Lock & Elevator Door Lock: Dual Safety Core from Nanjing Zhuye Elevatorparts

Elevator Door Triangle Lock and Elevator Door Lock are indispensable dual safety components for elevator door systems, working in tandem to safeguard the operational safety of elevators and the security of passengers. The elevator door lock acts as the primary safety barrier, which is automatically locked when the elevator door is closed and only unlocks when the car reaches the target floor accurately, ensuring the elevator cannot start if the door is not fully locked. The elevator door triangle lock is a dedicated maintenance and rescue component, allowing authorized technicians to manually open the elevator door in emergency situations or during maintenance without triggering the elevator’s safety shutdown. Exclusively supplied by Nanjing Zhuye Elevatorparts, a professional and trusted provider of high-quality elevator safety components, these Elevator Door Triangle Lock & Elevator Door Lock fully comply with international elevator safety standards (EN 81-20, GB 7588) and mechanical lock technical specifications. With reliable locking performance, strong anti-tampering capability, and excellent durability, they are widely applied in residential buildings, commercial complexes, office towers, airports, and other public facility elevators worldwide.

Nanjing Zhuye Elevatorparts adheres to the core philosophy of “Dual Protection, Safe Locking” and implements strict quality control throughout the production and inspection process of the elevator door triangle lock and door lock. Each unit undergoes multi-stage pre-delivery inspections, including locking force testing, wear resistance trials, anti-tampering performance detection, and compatibility verification. The components adopt advanced materials and manufacturing technology: the lock core and bolt of the elevator door lock are made of high-strength alloy steel, ensuring a locking force of ≥ 1200N and a mechanical service life of ≥ 5 million operations; the triangle lock is equipped with a unique triangular key interface, featuring strong anti-counterfeiting performance to prevent unauthorized opening; the shells of both components are made of corrosion-resistant stainless steel or flame-retardant engineering plastic, which can withstand the harsh environment of the elevator shaft (temperature -10℃ to 60℃, humidity 10% to 95%); the standardized mounting structure enables seamless matching with mainstream elevator door models, reducing installation difficulty and replacement costs.

Step-by-Step Usage Guide for Elevator Door Triangle Lock & Elevator Door Lock

To maximize the safety performance, service life, and operational reliability of the Elevator Door Triangle Lock and Elevator Door Lock, strictly follow the professional guidelines provided by Nanjing Zhuye Elevatorparts for selection, installation, and use:

1. Professional Selection & Installation

Installation must be conducted by certified elevator technicians proficient in elevator door systems. Prior to installation, refer to the compatibility manual provided by Nanjing Zhuye Elevatorparts to confirm that the triangle lock and door lock match the target elevator’s door model, door thickness, and control system. The installation steps are as follows:

Safety Preparation: Cut off the elevator’s main power supply and lock the power switch to prevent accidental power-on. Place a “Maintenance in Progress” warning sign at the elevator entrance. Fix the elevator door in the fully closed position with mechanical supports to avoid interference with installation.
Elevator Door Lock Installation: Install the elevator door lock on the designated position of the door frame using high-strength bolts provided by Nanjing Zhuye Elevatorparts. Adjust the position of the lock bolt to ensure it can accurately engage with the door latch when the door is closed, and the locking signal can be transmitted to the elevator controller in a timely manner. Ensure the lock body is firmly installed without looseness or shaking.
Elevator Door Triangle Lock Installation: Install the triangle lock on the outer side of the elevator door, aligning it with the linkage mechanism of the door lock. Fix it with dedicated screws, ensuring that the triangular key can smoothly drive the lock core to unlock the door when rotated, and the lock can automatically reset after use. After installation, test the fit between the two components to ensure they do not interfere with each other’s operation.

2. Correct Usage & Function Test

Correct use and regular function testing are crucial to ensuring the reliable operation of the two components. Follow these steps with reference to Nanjing Zhuye Elevatorparts’ technical guidelines:

Usage of Elevator Door Lock: The elevator door lock operates automatically during normal elevator operation. It is strictly prohibited to forcibly pry open the elevator door or tamper with the door lock, as this will trigger the elevator’s safety protection mechanism, causing the elevator to stop immediately and display an error code. If the door cannot be closed or locked normally, stop using the elevator immediately and contact professional maintenance personnel.
Usage of Elevator Door Triangle Lock: The triangle lock is only for use by authorized maintenance technicians. During maintenance or emergency rescue, insert the dedicated triangular key into the lock hole and rotate it 90 degrees (clockwise or counterclockwise according to the model) to unlock the door. After the operation is completed, close the door firmly and rotate the key in the reverse direction to reset the lock. The key must be kept by a dedicated person and must not be lent to unauthorized personnel.
Function Test: After installation or daily maintenance, test the locking and unlocking functions of the two components. Confirm that the door lock can be reliably locked when the elevator door is closed, and the elevator can start normally only when the lock is in the locked state. Test the triangle lock with a dedicated key to ensure smooth unlocking and resetting, and check that the door lock can still work normally after the triangle lock is used.

3. Daily Operation & Routine Maintenance

Regular inspection and maintenance are essential to early fault detection and ensuring the long-term stable operation of the elevator door triangle lock and door lock. Maintenance personnel should integrate the following checks into their daily patrol routines:

Daily Visual Inspection: During elevator patrols, check the external condition of the two components. Ensure the lock body, shell, and key hole are free of deformation, cracks, or corrosion; the triangle lock key hole is free of debris blockage; the door lock’s linkage mechanism is intact without jamming. Observe the elevator door’s closing status to ensure it can be fully locked and there is no abnormal gap.
Weekly Function Check: Use a dedicated triangular key to test the unlocking and resetting performance of the triangle lock. Manually check the locking tightness of the door lock, and use a torque wrench to detect the locking force to ensure it meets the standard requirements (≥ 1200N). If the door lock is loose or the triangle lock is stuck, adjust or maintain it in time.
Monthly Cleaning & Lubrication: Cut off the power supply and clean the surface of the lock body, key hole, and linkage mechanism with a soft, dry cloth to remove dust and debris. Apply a thin layer of special anti-rust lubricant (recommended by Nanjing Zhuye Elevatorparts) to the lock core, bolt, and other moving parts to ensure flexible operation and prevent rust and corrosion.

Recommended Replacement Cycle for Elevator Door Triangle Lock & Elevator Door Lock

As core safety components enduring long-term mechanical friction, environmental erosion (humidity, dust, vibration), and frequent use, the Elevator Door Triangle Lock and Elevator Door Lock have a specified service life. Timely replacement is critical to avoiding faults such as loose locking, difficult unlocking, or lock failure—issues that may lead to elevator operation errors, unauthorized door opening, or even serious safety accidents endangering personnel safety.

1. Standard Replacement Cycle

Under normal operating conditions (elevator daily operation time 12–24 hours, daily door opening/closing cycles ≥ 2000, environment temperature -10–60℃, humidity 10%–95%), the recommended replacement cycle for both the elevator door triangle lock and door lock is 6–8 years. This cycle is determined based on Nanjing Zhuye Elevatorparts’ long-term field operation data, wear tests, and global user feedback on elevator door systems.

2. Adjustments for Special Scenarios

Harsh Environments & High-Traffic Scenarios: For elevators in high-humidity coastal areas (salt spray corrosion), high-dust industrial sites, or ultra-high-traffic locations (e.g., large airports, central shopping malls) with daily door cycles ≥ 3500, the replacement cycle is shortened to 4–5 years. Harsh conditions and frequent use accelerate the wear of lock cores, bolts, and linkage mechanisms, significantly reducing the reliability of the components.
Low-Frequency Use Scenarios: For elevators with low usage frequency (e.g., villa elevators, small office buildings with daily operation time < 8 hours) and stable environments (constant temperature and humidity), the replacement cycle can be extended to 8–10 years—only if Nanjing Zhuye Elevatorparts’ professional technicians conduct an inspection and confirm that the locking performance, anti-tampering capability, and mechanical flexibility of the components meet the original factory standards.

3. Immediate Replacement Conditions

Replace the elevator door triangle lock or door lock immediately if any of the following issues occur, regardless of its service life:

The door lock cannot be fully locked, or the locking force is less than 800N, leading to frequent elevator interlock alarms or unstable operation.
The triangle lock is difficult to unlock or reset, or the key is stuck, affecting emergency rescue and maintenance work.
The lock core, bolt, or linkage mechanism is severely worn, bent, or broken, unable to achieve normal locking and unlocking functions.
The lock shell is severely corroded or damaged, and internal components are exposed, threatening electrical safety and anti-tampering performance.

In conclusion, the Elevator Door Triangle Lock and Elevator Door Lock supplied by Nanjing Zhuye Elevatorparts are high-quality, reliably compatible safety components tailored for modern elevator door systems.
