1. Professional Selection & Pre-Installation Preparation

Installation must be performed by certified elevator technicians. Prior to selection, confirm the elevator’s door machine model and door leaf thickness to ensure compatibility with the MKG161-01 door lock device. Consult Nanjing Zhuye Elevatorparts’ technical team if unsure about matching. Preparation steps: Cut off the elevator’s main power supply and secondary power supply, and lock the power switch; place a “Maintenance in Progress” warning sign at the elevator entrance and shaft access door; fix the elevator car at a flat floor with mechanical supports; open the car door and landing door panels, and disconnect the wiring of the old door lock device (take photos to record the wiring position); clean the door lock mounting position to remove dust, oil stains, and debris; prepare professional tools such as a screwdriver, multimeter, and torque wrench.

FunctionFunctionFunctionFunction2. Correct Installation & Precision Adjustment

Device Fixing: Take the Elevator Door Lock Device MKG161-01 from Nanjing Zhuye Elevatorparts, align it with the preset mounting holes on the door leaf or door frame, and fix it with stainless steel screws (torque: 4–6N·m). Ensure the device is installed horizontally without tilting, and the locking tongue can extend and retract smoothly without obstruction by door components.
Wiring Connection: According to the recorded wiring position and Nanjing Zhuye Elevatorparts’ wiring manual, connect the power cord, signal wire, and interlocking wire of the MKG161-01 device to the corresponding interfaces of the door machine controller. Distinguish between positive and negative poles and signal lines to avoid short circuits or signal failure. Tighten the wiring terminals firmly and use cable ties to organize the wire harness.
Function Calibration: Restore the secondary power supply first, and use a multimeter to test the input voltage of the device (ensure it matches the rated voltage: AC220V or DC24V). Manually open and close the door leaves to test the locking and unlocking functions—confirm the locking tongue extends and locks the door when the door is closed, and retracts smoothly when the door is opened. Test the interlocking signal: ensure the elevator controller receives the “door locked” signal only when the doors are fully closed, and the “door unlocked” signal when the doors are opened. Adjust the position of the device if there is a signal delay or failure.

3. Post-Installation Testing & Daily Maintenance

Comprehensive Function Testing: Restore the elevator’s main power supply and switch to inspection mode. Operate the elevator to run up and down, testing the door lock function at each floor: Confirm the doors lock automatically after the car departs, and unlock only when the car is leveled. Test the emergency unlocking function (using the emergency key) to ensure the doors can be opened manually in case of emergency. Use a signal tester to verify the stability of the interlocking signal.
Daily Inspection: Maintenance personnel should check the MKG161-01 device during daily shaft patrols: Observe the device’s shell for damage, deformation, or loose mounting screws; check the locking tongue for wear or jamming; listen for abnormal noise during locking/unlocking; clean the device surface and locking tongue with a dry cloth to remove dust and oil stains. Check the wiring terminals for looseness or oxidation regularly.
Regular Maintenance: Every 3 months, apply a small amount of special lubricant (recommended by Nanjing Zhuye Elevatorparts) to the locking mechanism and moving parts of the device to ensure flexible operation. Every 6 months, use a multimeter to test the resistance of the interlocking switch contacts (should be ≤ 1Ω) and check the insulation performance of the wiring. For elevators in high-humidity or dusty environments, shorten the maintenance interval to 1 month and recheck the device’s protection performance.

Recommended Replacement Cycle for Elevator Door Lock Device MKG161-01

As a core safety component enduring long-term mechanical movement, door opening/closing impact, environmental erosion (humidity, dust, temperature changes), and electronic component aging, the Elevator Door Lock Device MKG161-01 has a specified service life. Timely replacement is crucial to avoiding faults such as locking failure, interlocking signal delay, or unlocking jamming—issues that may lead to elevator operation accidents (e.g., the elevator running with doors open) or difficulty in opening doors during emergencies, endangering passenger safety.

1. Standard Replacement Cycle

Under normal operating conditions (elevator daily operation time 12–24 hours, daily door opening/closing times ≥ 1000, operating environment temperature -20℃ to 70℃, humidity 10%–95%), the recommended replacement cycle for the Elevator Door Lock Device MKG161-01 is 3–5 years. This cycle is determined based on Nanjing Zhuye Elevatorparts’ long-term field operation data, mechanical durability tests, and electronic component aging evaluations. The cycle fully considers the high-frequency use of elevator door systems and the impact of the shaft environment on component performance.

2. Adjustments for Special Scenarios

High-Traffic & Harsh Environments: For elevators in high-traffic areas (e.g., large shopping malls, airports with daily door opening/closing times ≥ 2000) or harsh environments (e.g., coastal areas with high salt spray, industrial sites with strong dust), the replacement cycle is shortened to 1.5–2.5 years. High-frequency door opening/closing accelerates the wear of the locking mechanism, while harsh environments cause rapid aging of electronic components and corrosion of the lock body.
Low-Frequency Use & Stable Environments: For elevators with low usage frequency (e.g., villa elevators, small office buildings with daily operation time < 8 hours) and stable shaft environments (constant temperature and humidity, little dust), the replacement cycle can be extended to 5–7 years—only after Nanjing Zhuye Elevatorparts’ technicians inspect and confirm that the locking force, interlocking signal, and electronic component performance meet factory standards.

3. Immediate Replacement Conditions

Replace the Elevator Door Lock Device MKG161-01 immediately if any of the following issues occur, regardless of its service life:

The locking tongue is severely worn or deformed, leading to insufficient locking force (＜1000N) or failure to lock the door leaves firmly.
The interlocking signal is delayed or lost, causing the elevator to fail to receive the “door locked” signal (elevator cannot start) or to run with doors open.
The electronic components (e.g., interlocking switch, wiring) are aging or damaged, leading to frequent device malfunctions that cannot be repaired by maintenance.
The lock body is severely corroded, cracked, or damaged due to impact, and the locking mechanism is stuck—making it impossible to open or close the doors normally.
