Elevator OL35M Speed Limiter 900540G23: Core Safety Component from Nanjing Zhuye Elevatorparts
The elevator speed limiter is the “safety core” of the elevator overspeed protection system, responsible for monitoring the elevator’s running speed in real time. When the elevator exceeds the rated speed or experiences a free fall, it immediately triggers the safety clamp to brake the car, preventing serious safety accidents. As a key protective component in the elevator system, its reliability is directly related to the lives of passengers. The Elevator OL35M Speed Limiter 900540G23, exclusively supplied by Nanjing Zhuye Elevatorparts, is meticulously designed for modern passenger and freight elevators. Fully compliant with international standards such as IEC/EN 60947 and GB/T 7588-2022, this speed limiter features a precision mechanical structure, stable speed monitoring performance, and reliable action triggering mechanism. 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 office buildings, providing a solid safety barrier for elevator operation.
Nanjing Zhuye Elevatorparts adheres to strict quality control standards, and the OL35M 900540G23 Elevator Speed Limiter is a concentrated embodiment of this philosophy. Each speed limiter undergoes multiple rigorous tests before leaving the factory, including action speed calibration, wear resistance testing, high-temperature (up to 80℃) and low-temperature (down to -30℃) resistance tests, and corrosion resistance tests. The main body is made of high-strength alloy steel through precision casting, ensuring structural stability even under extreme working conditions. The internal gear and rotating components adopt high-precision machining technology, ensuring accurate speed monitoring with an error of less than ±3%. The action speed calibration seal is intact and anti-tamper, in line with the core requirements of TSG T7001-2023. In addition, the built-in buffer structure reduces impact during action, extending the service life of the speed limiter and safety clamp system.
Usage Guide for Elevator OL35M Speed Limiter 900540G23
Correct installation, debugging, and regular calibration are crucial to ensuring the safety performance of the OL35M 900540G23 Speed Limiter. Nanjing Zhuye Elevatorparts strongly recommends that only professional and certified elevator maintenance technicians perform installation, debugging, and calibration operations, as the speed limiter involves core safety protection functions, and improper operation may lead to failure to trigger protection in case of overspeed. Before use, confirm that the model, rated speed, and action speed parameters of the speed limiter are completely consistent with the elevator system. For detailed installation steps, calibration standards, and parameter requirements, refer to the product manual provided by Nanjing Zhuye Elevatorparts, or contact our technical support team for professional guidance.
1. Pre-Installation Preparation
First, cut off the main power supply of the elevator, lock the power switch, and place a “Maintenance in Progress” warning sign at the elevator entrance and machine room to prevent accidental startup. Operate the elevator car to the middle floor to avoid interference with the installation. Prepare professional tools such as screwdrivers, torque wrenches, speed testers, and wire brushes. Clean the installation position (usually in the machine room) to remove dust, debris, and oil stains, as these impurities may affect the rotation flexibility of the speed limiter. Carefully inspect the OL35M 900540G23 speed limiter for external damage, such as cracks on the main body, damage to the rotating shaft, or missing calibration seals. Check whether the accessories such as the speed limiter rope, tension device, and connecting pins are complete.
Debugg2. Installation & Adjustment
Fix the OL35M 900540G23 Speed Limiter on the dedicated mounting bracket in the machine room, ensuring that the installation is firm and horizontal, with no shaking. Note that the tightening torque of the fixing bolts should be strictly in accordance with the specifications provided by Nanjing Zhuye Elevatorparts. Install the speed limiter rope, ensuring that the rope is properly tensioned by the tension device and that the rope groove is aligned to avoid rope deviation. Connect the speed limiter’s electrical safety switch to the elevator safety circuit to ensure that the elevator stops immediately when the speed limiter acts. After installation, debug the speed monitoring function: use a professional speed tester to simulate the elevator’s overspeed state and confirm that the speed limiter can trigger the safety clamp reliably at the preset action speed. Check that the calibration seal is intact and mark the installation date and calibration information.
3. Debugging & Daily Use
According to TSG T7001-2023 and the recommendations of Nanjing Zhuye Elevatorparts, the OL35M 900540G23 Speed Limiter must undergo regular action speed calibration: for speed limiters used for 15 years or less, calibration is required every 2 years; for those used for more than 15 years, annual calibration is mandatory. During daily maintenance, follow TSG T5002—2017 regulations: clean the speed limiter body and rotating components with a wire brush monthly to remove dust and rust; check the tightness of the rope and the wear of the rope groove quarterly; lubricate the rotating shaft with special lubricating oil annually. Regularly inspect the calibration seal—if it is damaged or missing, stop using the elevator immediately and contact professional technicians from Nanjing Zhuye Elevatorparts for re-calibration and seal replacement. Avoid using water or corrosive cleaning agents to prevent damage to internal components.
Replacement Cycle of Elevator OL35M Speed Limiter 900540G23
The replacement cycle of the OL35M 900540G23 Elevator Speed Limiter is affected by factors such as usage frequency, operating environment, and maintenance quality. Under normal use conditions—elevator operation time is 12-24 hours a day, the operating environment is dry and well-ventilated, and regular calibration and maintenance are performed—Nanjing Zhuye Elevatorparts recommends a replacement cycle of 10-15 years. This cycle is formulated based on a large number of field test data and GB/T31821—2015 “Technical Conditions for Scrap of Elevator Main Components”, fully considering the main factors affecting performance, such as wear of internal mechanical components, aging of the spring mechanism, and attenuation of speed monitoring accuracy.
For elevators in high-traffic areas such as shopping malls, airports, and subway stations, where the number of daily operations exceeds 1000 times, or in harsh environments with high humidity, heavy dust, or large temperature fluctuations, the replacement cycle should be shortened to 8-12 years. High-frequency operation accelerates the wear of internal gears and rotating shafts, while harsh environments easily cause corrosion of the main body and damage to the rope. For elevators with low usage frequency, such as villa elevators and small office buildings with daily operation time less than 8 hours, if maintained properly and calibrated on schedule, the replacement cycle can be extended to 15-20 years. However, professional technicians from Nanjing Zhuye Elevatorparts should conduct semi-annual inspections on speed limiters over 15 years old, focusing on testing action sensitivity, structural integrity, and rope wear.
Regardless of the service life, the OL35M 900540G23 Speed Limiter should be replaced immediately if any of the following problems occur: the action speed exceeds the allowable error range and cannot be corrected by calibration; the rotating components are stuck or severely worn, affecting speed monitoring; the main body is cracked, corroded, or deformed; the calibration seal is damaged and cannot be re-calibrated; the speed limiter fails to trigger the safety clamp during the linkage test; the speed limiter cannot pass the annual safety inspection. Timely replacement of the speed limiter is critical to avoid serious safety accidents such as elevator overspeed and free fall.
The Elevator OL35M Speed Limiter 900540G23 from Nanjing Zhuye Elevatorparts combines precise speed monitoring, reliable action performance, and long service life, making it an ideal choice for elevator maintenance and renovation.
