The elevator hydraulic buffer is a critical energy-dissipating safety component installed at the bottom of the elevator shaft, serving as the “last line of defense” to protect passengers and equipment when the elevator overspeeds or malfunctions. The Elevator Hydraulic Buffers OBC16B and OBC20B launched by Nanjing Zhuye Elevatorparts are high-performance devices tailored for mainstream elevator systems, widely compatible with renowned brands such as Schindler, OTIS, and KONE. As energy-dissipating buffers, they absorb the kinetic energy of the car or counterweight through hydraulic oil throttling, ensuring a smooth and gentle deceleration to avoid violent impacts. Crafted with high-strength steel casings, precision hydraulic cylinders, and wear-resistant seals, these buffers strictly comply with international elevator safety standards (EN 81-20, GB 7588-2003) and have become a trusted choice for global elevator maintenance teams and manufacturers.
Nanjing Zhuye Elevatorparts adheres to the “quality first, safety-oriented” principle, implementing strict quality control throughout the production process of OBC16B and OBC20B hydraulic buffers. Each unit undergoes rigorous testing, including buffer stroke verification, load-bearing capacity testing, seal tightness inspection, and high-temperature resistance assessment, ensuring stable parameters (OBC16B and OBC20B with different stroke and load specifications) and long-term reliable operation. The buffer’s high-strength steel casing can withstand strong impact forces without deformation, while the precision-machined hydraulic cylinder ensures smooth oil flow and stable buffering performance. The imported wear-resistant seals effectively prevent oil leakage, and the built-in oil filter avoids pipeline blockage caused by impurities, making it suitable for the harsh operating environment of elevator shafts (operating temperature range: -10℃ to 60℃).
Usage Guide for Elevator Hydraulic Buffer OBC16B & OBC20B
Correct installation, debugging, and daily inspection of OBC16B and OBC20B hydraulic buffers are crucial to ensuring the elevator’s final safety protection function. Nanjing Zhuye Elevatorparts strongly recommends that only certified elevator maintenance technicians perform installation and maintenance, as improper operation may lead to buffer failure and serious safety accidents.
1. Pre-Installation Preparation
First, confirm that the A3N53390 display board matches the elevator model (check parameters such as voltage, interface type, and installation dimensions). Consult Nanjing Zhuye Elevatorparts’ technical team immediately if there is any doubt about compatibility. Then, cut off the elevator’s main power supply and control cabinet power supply, lock the switch, and place a “Maintenance in Progress” warning sign at the elevator entrance. Remove the old display board from the cab or landing hall panel, and take photos to record the wiring direction and terminal connections for future reference. Finally, prepare professional tools including a screwdriver, wire stripper, multimeter, and anti-static gloves, and clean the installation area to remove dust, debris, and oil stains.
First, confirm that the buffer model (OBC16B/OBC20B) matches the elevator model (check parameters such as rated load, buffer stroke, and installation dimensions). Consult Nanjing Zhuye Elevatorparts’ technical team immediately if there is any uncertainty about compatibility. Then, cut off the elevator’s main power supply, lock the switch, and place a “Maintenance in Progress” warning sign at the elevator entrance and shaft access door. Fix the elevator car at the top floor position to avoid accidental fall during installation. Finally, prepare professional tools including a crane, wrench, level, and torque wrench, and clean the buffer installation base in the shaft to remove dust, debris, and oil stains, ensuring the base is flat and firm.
Use a crane to hoist the new OBC16B/OBC20B buffer from Nanjing Zhuye Elevatorparts to the installation base, ensuring the buffer’s direction is correct (the oil filling port faces upward). Place the buffer on the base, adjust it with a level to ensure it is vertically installed (verticality error ≤1mm/m), and fix it firmly with foundation bolts. After fixing, check the buffer’s stroke space—ensure there is no obstruction between the buffer plunger and the car/counterweight buffer plate. Fill the buffer with hydraulic oil of the type recommended by Nanjing Zhuye to the specified oil level, and tighten the oil filling port. Connect the buffer’s auxiliary switch (if equipped) to the elevator safety circuit strictly following the wiring manual, ensuring firm connections. After installation, perform a static pressure test: slowly lower the car to press the buffer plunger to the maximum stroke, and check for oil leakage; release the pressure, and the plunger should reset automatically and smoothly.
3. Daily Use & Maintenance
According to the “Elevator Maintenance Rules” (TSG T5002-2017) and Nanjing Zhuye’s recommendations, OBC16B and OBC20B hydraulic buffers should be inspected monthly and undergo professional comprehensive testing annually. For daily maintenance: Check the buffer’s external surface for cracks, deformation, or corrosion; confirm the oil filling port and seal are intact without oil leakage. Clean the buffer surface and surrounding area regularly to remove dust and debris, ensuring the plunger can move freely. Every 3 months, check the oil level and oil quality—if the oil is turbid or contains impurities, replace it immediately; if the oil level is too low, supplement it to the specified level. Check the auxiliary switch’s on-off state with a multimeter to ensure it can act reliably when the buffer is triggered. If any abnormality is found, stop using the elevator immediately and contact Nanjing Zhuye’s after-sales team for maintenance.
Replacement Cycle of Elevator Hydraulic Buffer OBC16B & OBC20B
The replacement cycle of OBC16B and OBC20B hydraulic buffers is closely related to operating conditions and maintenance quality. Under normal conditions (elevator daily operation 12-24 hours, no frequent overload, shaft environment dry and clean), Nanjing Zhuye Elevatorparts recommends a replacement cycle of 5-8 years. This cycle is determined based on long-term field operation data and component aging tests, fully considering the wear of seals, attenuation of hydraulic oil performance, and fatigue of mechanical structures.
For elevators in high-traffic areas (e.g., large shopping malls, airports with frequent elevator use) or harsh environments (shaft with high humidity, heavy dust, or large temperature fluctuations), the replacement cycle should be shortened to 3-5 years. Frequent impact accelerates the wear of internal components, while harsh environments cause corrosion of the casing and deterioration of hydraulic oil. For low-usage elevators (e.g., villa elevators, small office buildings with daily operation time <8 hours) in stable environments, the cycle can be extended to 8-10 years, but only after annual professional testing by Nanjing Zhuye’s technicians confirms that the buffer’s stroke, sealing performance, and buffering capacity meet safety standards.
Replace the OBC16B/OBC20B buffer immediately if any of the following issues occur, regardless of its service life: Obvious cracks, deformation, or severe corrosion on the casing; persistent oil leakage that cannot be repaired; the plunger fails to reset automatically or resets slowly; the buffer stroke is less than the rated value; the auxiliary switch malfunctions and cannot trigger the safety circuit; the buffer fails to pass the annual professional safety test.
