How to Choose the Right Elevator Door Operator System Components?
The elevator door operator system is the most frequently moving, most easily worn, and most experience-defining part of the entire elevator operation. The smoothness of door opening and closing not only affects building operation efficiency but is also directly related to passenger safety. Therefore, choosing the right door operator system components is a crucial step in maintenance, modernization, and new elevator projects.
Today, the technical team from A-FLY Elevator & Escalator Parts Supplier will explain how to select reliable and durable elevator door operator parts and the key factors you must pay attention to before purchasing.
1. Identify the Brand of the Door Operator and System Compatibility
Different brands of door operators have different track dimensions, drive motors, door knife structures, door lock signal requirements, and control board parameters. Therefore, when selecting replacement parts, you must ensure:
Whether the elevator door operator motor matches the original system voltage
Whether the drive board signals are compatible
Whether the hanger roller dimensions match
Whether the door knife and door lock fit the original mechanism
A-FLY provides multi-brand compatible door operator components, helping solve the common issue of “incompatible models” during old elevator upgrades.
2. Choose High-Wear-Resistance Door Hanger Rollers and Guiding Components
Door hanger rollers and guide shoes are the most frequently worn parts in the door operator system. Low-quality rollers tend to cause:
Increased noise
Unstable door speed
Accelerated wear on the door track
When selecting hanger rollers, pay attention to:
Whether the wheel material uses wear-resistant nylon or polyurethane
Whether the bearings are high-precision and silent
Whether the dimensions (outer diameter, inner hole, thickness) match the original part
A-FLY door hanger rollers undergo dynamic balance and wear-resistance tests, suitable for high-frequency operation environments.
3. Focus on Door Operator Motor Stability and Voltage Compatibility
The door operator motor is the power core of the entire system. Its performance determines door speed, torque, and smoothness. Common voltages include DC24V, AC110V, AC220V.When selecting a motor, confirm:
If the voltage matches the original system
Whether the torque meets the requirements of the door width and door weight
Whether the motor has overheat and overload protection
A-FLY provides motors compatible with multiple brands and supports OEM customization.
4. Choose High-Sensitivity Door Locks and Light Curtain Sensors
Safety is the top priority of the door operator system. Door locks and light curtains are crucial to preventing mis-closing and entrapment accidents.When purchasing, ensure:
Door lock switch signals are stable, with no false triggering
Light curtain density is high with fast response
Supports multiple voltage inputs (12V / 24V)
Dust-proof and water-proof performance meets standards
A-FLY light curtain series features high responsiveness and strong anti-interference capability, widely used in modernization projects and high-traffic buildings.
