Elevator Hall Door Triangular Lock & Hall Door Lock: Safety Guardian from Nanjing Zhuye Elevatorparts
Elevator Hall Door Triangular Lock and Elevator Hall Door Lock are core safety components for elevator hall door systems, forming a dual safety barrier to ensure the safe operation of elevators. The hall door lock serves as the primary “safety interlock,” which can only be unlocked when the elevator car is accurately aligned with the floor and ensures the elevator cannot start if the hall door is not fully locked. The triangular lock is a dedicated maintenance tool interface, allowing authorized technicians to manually open the hall door for maintenance or rescue under specific conditions. These two components work in tandem to prevent unauthorized access to the elevator shaft and avoid safety accidents caused by abnormal opening of the hall door. Exclusively supplied by Nanjing Zhuye Elevatorparts, a professional and trusted provider of high-quality elevator safety components, theseElevator Hall Door Triangular Lock & Hall 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 “Safety First, Reliable Locking” and implements strict quality control throughout the production and inspection process of the hall door triangular lock and hall 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 hall door lock are made of high-strength alloy steel, ensuring a locking force of ≥ 1000N and a mechanical service life of ≥ 5 million operations; the triangular lock is equipped with a special triangular key interface, which is highly anti-counterfeiting and can effectively prevent unauthorized opening; the shell of both components is made of corrosion-resistant stainless steel or engineering plastic, adapting to the harsh environment of the elevator shaft (humidity 10%-95%, temperature -10-60℃); standardized mounting structures enable seamless matching with mainstream elevator hall door models, reducing installation and replacement costs.
Step-by-Step Usage Guide for Elevator Hall Door Triangular Lock & Hall Door Lock
To maximize the safety performance, service life, and operational reliability of the Elevator Hall Door Triangular Lock and Hall Door Lock, strictly follow the professional guidelines provided by Nanjing Zhuye Elevatorparts for use, installation, and maintenance:
1. Professional Selection & Installation
Installation must be conducted by certified elevator technicians proficient in hall door systems. Prior to installation, refer to the compatibility manual provided by Nanjing Zhuye Elevatorparts to confirm that the triangular lock and hall door lock match the target elevator’s hall door model, door thickness, and interlock 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 hall door in the fully closed position with mechanical supports to avoid interference with installation.
-
Hall Door Lock Installation: Install the hall door lock on the designated position of the hall 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 hall door latch when the door is fully 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.
-
Triangular Lock Installation: Install the triangular lock on the outer panel of the hall door, aligning it with the linkage mechanism of the hall door lock. Fix it with dedicated screws, ensuring that the triangular key can smoothly drive the lock core to unlock the hall door when rotated, and the lock can automatically reset after use.
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 Hall Door Lock: The hall door lock is automatically locked when the elevator hall door is closed. Only when the elevator car arrives at the floor and the car door is aligned with the hall door, the door opening mechanism of the car can drive the hall door lock to unlock. It is strictly prohibited to forcibly pry open the hall door or tamper with the hall door lock, as this will trigger the elevator’s safety protection mechanism and cause the elevator to shut down.
-
Usage of Triangular Lock: The triangular lock can only be used by authorized maintenance technicians. When maintenance or rescue is required, insert the dedicated triangular key into the lock hole and rotate it 90 degrees clockwise (or counterclockwise, depending on the model) to unlock the hall door. After the operation is completed, close the hall door firmly and rotate the key in the reverse direction to reset the triangular lock. The key must be kept by a dedicated person to prevent loss or misuse.
-
Function Test: After installation or daily maintenance, test the locking and unlocking functions of the two components. Confirm that the hall door lock can be reliably locked when the hall door is closed, and the elevator can start normally only when the lock is in the locked state. Test the triangular lock with a dedicated key to ensure smooth unlocking and resetting, and the hall door can be tightly closed after resetting.
3. Daily Operation & Routine Maintenance
Regular inspection and maintenance are essential to early fault detection and ensuring the long-term stable operation of the hall door triangular lock and hall 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 triangular lock key hole is free of debris blockage; the hall door lock’s linkage mechanism is intact without jamming. Observe the hall 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 triangular lock. Manually check the locking tightness of the hall door lock, and use a torque wrench to detect the locking force to ensure it meets the standard requirements (≥ 1000N). If any abnormality is found, 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.
Recommended Replacement Cycle for Elevator Hall Door Triangular Lock & Hall Door Lock
As core safety components enduring long-term mechanical friction, environmental erosion (humidity, dust, vibration), and frequent use, the Elevator Hall Door Triangular Lock and Hall 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 unauthorized opening of the hall door, elevator operation errors, or even serious safety accidents endangering personnel safety.
1. Standard Replacement Cycle
Under normal operating conditions (elevator daily operation time 12–24 hours, daily hall door opening/closing cycles ≥ 2000, environment temperature -10–60℃, humidity 10%–95%), the recommended replacement cycle for both the hall door triangular lock and hall 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 hall 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 hall 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 hall door triangular lock or hall door lock immediately if any of the following issues occur, regardless of its service life:
-
The hall door lock cannot be fully locked, or the locking force is less than 800N, leading to unstable operation of the elevator or frequent interlock alarms.
-
The triangular lock is difficult to unlock or reset, or the key is stuck, affecting maintenance and rescue 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.
