Both products comply with international elevator safety standards (EN 81-20, GB 10058) and are trusted by global elevator maintenance teams for their high reliability and durability.
Nanjing Zhuye Elevatorparts adheres to the “quality first, safety-oriented” principle, implementing strict quality control throughout the production of elevator triangular locks and top rods. Each triangular lock undergoes rigorous tests including lock core wear resistance, structural strength, and anti-tampering performance; the top rod is made of high-strength alloy steel, with precise dimensional calibration and anti-corrosion treatment. The triangular lock features a unique anti-misoperation design to prevent opening by non-professionals, while the top rod has a load-bearing capacity of up to 5000N and can withstand extreme temperatures from -20℃ to 80℃. Both products are equipped with wear-resistant components, ensuring stable performance in harsh environments such as elevator shafts and machine rooms.
Usage Guide for Elevator Triangular Lock & Elevator Top Rod
Correct use of elevator triangular locks and top rods is crucial to avoid safety accidents such as falls or car misoperation. Nanjing Zhuye Elevatorparts emphasizes that only certified elevator maintenance technicians are allowed to use these components, and all operations must comply with elevator maintenance safety regulations.
1. Pre-Installation Preparation
First, confirm that the elevator’s MAC car lighting controller model matches the POWCV24181MH power supply (check parameters such as input voltage, output voltage, output current, and installation dimensions). Consult Nanjing Zhuye Elevatorparts’ technical team if there is any uncertainty about compatibility. Then, cut off the elevator’s main power supply and the secondary power supply for the car lighting system, lock the switch, and place a “Maintenance in Progress” warning sign at the elevator landing doors and machine room entrance. Locate the power supply installation position (usually on the car top or in the car control cabinet) and clean the area to remove dust, debris, and oil stains. Finally, prepare professional tools such as a screwdriver, wire stripper, multimeter, and insulation tester, and check that the new POWCV24181MH power supply from Nanjing Zhuye Elevatorparts is intact (no damage to the shell, no loose pins).
First, confirm that the triangular lock and top rod models match the elevator type (check dimensions, interface, and load-bearing parameters). Consult Nanjing Zhuye Elevatorparts’ technical team for compatibility verification if uncertain. Cut off the elevator’s main power supply, lock the switch, and place a “Maintenance in Progress” warning sign at the landing entrance. For triangular lock use: Ensure sufficient lighting at the landing door and clear surrounding obstacles; confirm the car position via the elevator control system or observation window to avoid opening the door when the car is not at the floor. For top rod use: Prepare auxiliary tools such as a wrench, level, and safety belt; check that the top rod’s surface is free of deformation or cracks and that the connecting parts are tight.
2. Standard Operation Procedures
For Elevator Triangular Lock: Insert the triangular key into the lock hole, confirm the unlocking direction, and slowly turn to unlock . Do not open the door fully immediately; first push it open 100mm to observe the shaft situation, then fully open after confirming safety. After maintenance, close the landing door firmly and check that the lock core is fully reset to ensure the door is reliably locked . For Elevator Top Rod (Brake-Releasing Type): Fix the car in a safe position, put on a safety belt, and stand on a stable platform. Align the top rod with the elevator brake release device according to Nanjing Zhuye’s technical manual, and slowly apply force to release the brake . Cooperate with another technician to use the handwheel to move the car to the target floor, then slowly release the top rod to reset the brake. During operation, avoid excessive force to prevent damage to the brake system.
3. Daily Maintenance & Post-Operation Testing
After operation, test the elevator’s normal operation: For the triangular lock, check that the landing door cannot be opened without the key; for the top rod, confirm the brake works normally and the car runs stably without sliding. For daily maintenance: Inspect the triangular lock monthly—lubricate the lock core with special oil, check for loose screws or wear, and ensure the key turns smoothly. Inspect the top rod quarterly—check for corrosion, deformation, or fatigue cracks, re-tighten loose connecting parts, and verify load-bearing performance . Store both components in a dry, dust-free environment; the triangular key should be kept by a dedicated person with strict access control to prevent misuse.
Replacement Cycle of Elevator Triangular Lock & Elevator Top Rod
The replacement cycle of elevator triangular locks and top rods depends on usage frequency and working environment. Under normal conditions (elevator daily operation 12-24 hours, regular maintenance, dry and low-dust environment), Nanjing Zhuye Elevatorparts recommends a replacement cycle of 3-5 years. This cycle is determined based on long-term field data and material aging tests, considering lock core wear, top rod metal fatigue, and structural performance attenuation.
For elevators in high-traffic areas (malls, airports with frequent maintenance) or harsh environments (high humidity, heavy dust, large temperature fluctuations), shorten the replacement cycle to 2-3 years. Frequent use accelerates lock core wear and top rod fatigue, while harsh environments worsen corrosion. For elevators with low usage (villas, small offices) or those using non-magnetic top rods (for special brake systems ), the cycle can be extended to 5-6 years after Nanjing Zhuye technicians confirm performance meets safety standards.
Replace immediately regardless of service life if: The triangular lock’s key is stuck, the lock core cannot be reset, or the landing door cannot be reliably locked; the top rod is deformed, cracked, or shows obvious corrosion (affecting load-bearing); either component fails to function normally during maintenance/rescue; wear exceeds the standard (e.g., triangular lock key slot wear >0.5mm, top rod diameter reduction >2%). For brake-releasing top rods, replace immediately if they fail to match the brake system after elevator upgrades.
