Usage Guide for Elevator Door Hanging Wheel 62166203

Correct installation, debugging, and maintenance of the 62*16*6203 door hanging wheel are crucial to ensuring the stable operation of the elevator door machine pulley system. Nanjing Zhuye Elevatorparts emphasizes that only certified elevator maintenance technicians are allowed to perform installation and replacement operations to avoid door jamming or falling hazards.

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 elevator door model matches the 62*16*6203 door hanging wheel (check parameters such as outer diameter, width, and bearing model). Consult Nanjing Zhuye Elevatorparts’ technical team if there is any uncertainty about compatibility. Then, cut off the elevator’s main power supply and door system power supply, lock the switch, and place a “Maintenance in Progress” warning sign at the landing. Fix the elevator door in a closed state with wooden wedges to prevent accidental movement. Finally, prepare professional tools such as a screwdriver, wrench, pulley removal tool, and lubricant; clean the door hanging wheel installation area, guide rail, and door machine active pulley to remove dust and debris.

2. Installation & Wiring

If replacing old door hanging wheels, first take photos to record their installation position, direction, and connection with the door plate for later reference. Use a pulley removal tool to loosen the fixing bolts of the old wheel, disconnect the door plate connection, and remove the old wheel. Take the new 62*16*6203 door hanging wheel from Nanjing Zhuye Elevatorparts, install it on the door hanging bracket, and fasten it firmly with bolts (torque value: 6-8 N·m). Ensure the wheel rotates smoothly without jamming. Connect the door plate to the hanging wheel, adjust the height of the bracket to ensure the door hanging wheel is closely attached to the guide rail (gap ≤ 0.5mm) and the door is horizontal. Check the coordination between the door hanging wheel and the door machine active pulley—ensure the transmission belt is tight and stress-free.

Debugg3. Operation & Daily Maintenance

Remove the wooden wedges fixing the door, restore the power supply, and switch the elevator to inspection mode. Operate the elevator door to open and close repeatedly, observing whether the door runs smoothly without jitter or abnormal noise. Check if the 62*16*6203 door hanging wheel rotates flexibly and the guide rail is free of abnormal friction. After 1 hour of stable operation, check the temperature of the hanging wheel (slightly warm is normal). For daily maintenance, inspect the door hanging wheel during weekly door system patrols: Check for wear, cracks, or deformation of the rubber rim; confirm the bearing rotates smoothly without noise; clean the wheel surface and guide rail with a dry cloth. Apply special bearing lubricant every 3 months to reduce friction. At the same time, check the door machine active pulley and transmission belt—abnormal wear of the active pulley may accelerate the damage of the door hanging wheel.

Replacement Cycle of Elevator Door Hanging Wheel 62166203

The replacement cycle of the 62*16*6203 door hanging wheel is closely related to operating frequency and environment. Under normal circumstances (elevator daily operation 12-24 hours, daily door opening and closing times ≤ 1500, dry and low-dust environment), Nanjing Zhuye Elevatorparts recommends a replacement cycle of 2-3 years. This cycle is determined based on long-term field operation data and wear tests, fully considering the wear of the rubber rim and the aging of the built-in bearing.

For elevators in high-traffic areas (e.g., large shopping malls, airports with daily door opening and closing times ≥ 2000) or harsh environments (high humidity, heavy dust, large temperature fluctuations), the replacement cycle should be shortened to 1-1.5 years. High-frequency operation accelerates the wear of the rubber rim and bearing, while harsh environments easily cause corrosion and jamming. 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 3-4 years, but only after inspection and confirmation by Nanjing Zhuye’s technicians that the hanging wheel’s rotation performance and coordination with the door machine pulley system meet standards.

Replace the door hanging wheel immediately if any of the following issues occur, regardless of its service life: The rubber rim is severely worn (thickness reduction ≥ 3mm), cracked, or falls off; the bearing is stuck, loose, or makes abnormal noise; the wheel body is deformed or cracked, causing the door to jitter during operation; the hanging wheel slips on the guide rail, affecting door opening and closing accuracy; the wheel cannot coordinate with the door machine active pulley normally, leading to uneven door speed.
