Usage Guide for Elevator Door Operator Belt SPZ1080LW/3V425
Correct installation, tension adjustment, and maintenance of the SPZ1080LW/3V425 elevator door operator belt are crucial to ensuring the smooth operation of the elevator door system. Nanjing Zhuye Elevatorparts strongly recommends that only certified elevator maintenance technicians perform installation and maintenance to avoid safety hazards such as door jamming or abnormal stopping.
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 SPZ1080LW/3V425 door operator belt matches the elevator door operator model (check specifications such as belt type, length, and section). 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. Open the door operator cover and fix the elevator door in an open position with a support rod to prevent accidental closing. Finally, prepare professional tools including a screwdriver, wrench, tension gauge, and belt puller, and clean the door operator pulleys, tensioners, and installation area to remove dust, debris, and oil stains.
2. Installation & Tension Adjustment
Loosen the door operator tensioner to remove the old belt. Take photos to record the old belt’s winding direction on the pulleys for future reference. Take the new SPZ1080LW/3V425 door operator belt from Nanjing Zhuye Elevatorparts and wind it around the driving pulley and driven pulley strictly according to the recorded direction. Adjust the tensioner to apply appropriate tension to the belt—use a tension gauge to measure, with the recommended tension range being 15-20N (refer to Nanjing Zhuye’s technical manual). Ensure the belt is properly aligned with the pulleys (no deviation) and that both sides of the belt are in close contact with the pulley grooves. After adjustment, manually rotate the pulleys to check if the belt runs smoothly without jamming or slipping. Tighten the tensioner fixing screws firmly to prevent loosening during operation.
3. Daily Maintenance & Post-Operation Testing
Close the door operator cover, restore the power supply, and test the elevator door’s automatic opening and closing function: the door should open and close smoothly without delay, slipping, or abnormal noise. After 1 hour of stable operation, check the belt’s working status—no obvious heating or loosening is allowed. For daily maintenance, inspect the belt during monthly patrols: check for cracks, peeling, or wear on the belt surface; confirm the belt tension is normal (the belt should deflect 5-8mm when pressed with a force of 10N); clean the belt and pulleys with a dry cloth to remove dust and debris. Avoid using oil or grease on the belt (it will cause slipping). Every 3 months, recheck the tension; every 6 months, inspect the pulleys for wear and replace them if necessary to prevent abnormal wear of the belt.
Replacement Cycle of Elevator Door Operator Belt SPZ1080LW/3V425
The replacement cycle of the SPZ1080LW/3V425 elevator door operator belt is closely related to operating frequency and working environment. Under normal conditions (elevator daily operation 12-24 hours, door opening and closing ≥500 times/day, clean and dry environment), Nanjing Zhuye Elevatorparts recommends a replacement cycle of 1-2 years. This cycle is determined based on long-term field operation data and material aging tests, fully considering the wear of the belt surface, fatigue of internal cords, and performance attenuation.
For elevators in high-traffic areas (e.g., large shopping malls, airports with door opening and closing ≥1000 times/day) or harsh environments (high humidity, heavy dust, high temperature, or oil pollution), the replacement cycle should be shortened to 6-12 months. High-frequency operation accelerates belt wear, while harsh environments cause rubber aging and internal cord corrosion. For low-usage elevators (e.g., villa elevators, small office buildings with door opening and closing <200 times/day) in stable environments, the cycle can be extended to 2-3 years, but only after inspection and confirmation by Nanjing Zhuye’s technicians that the belt’s tension and wear degree meet safety standards.
Replace the SPZ1080LW/3V425 door operator belt immediately if any of the following issues occur, regardless of its service life: The belt has obvious cracks, peeling, or wear (the fabric layer is exposed); the belt is stretched excessively (tension cannot be adjusted to the standard range); the belt slips frequently during operation, causing the door to open and close slowly or abnormally; the belt is contaminated by oil or chemicals and cannot be cleaned; the belt makes obvious abnormal noise (such as squeaking) during operation.
