1. Function
- Anti-pinch Protection: When the elevator door is closing, if the safety edge detects an obstruction (such as a person or object), the door will immediately stop closing and reopen, preventing injuries or damage.
- High Sensitivity: Safety edges typically use infrared or mechanical sensing technology to respond quickly, ensuring timely detection of obstructions during door closure.
2. Types
- Mechanical Safety Edge: Detects obstacles through physical contact. When the edge touches an object, it triggers the door to reopen.
- Infrared Sensor Type: Uses infrared beams to detect obstructions between the doors without physical contact, offering higher sensitivity.
3. Installation Location
- Safety edges are usually installed along the edges of elevator doors, on both the left and right sides, ensuring full coverage of the door gap during closure.
4. Maintenance and Inspection
- Regular Checks: Ensure the sensitivity and functionality of the safety edge are normal to avoid failures due to aging or damage.
- Cleaning and Upkeep: Keep the surface of the safety edge clean to prevent dust or debris from affecting its performance.
5. Safety Standards
- The design of home elevator safety edges must comply with relevant safety standards (e.g., EN 81-20/50) to ensure reliability and durability.
6. Precautions
- Frequent false triggers may indicate overly sensitive settings or a malfunction, requiring prompt adjustment or repair.
- Avoid placing objects near the safety edge to ensure its proper operation.
The safety edge is a critical component for ensuring passenger safety in home elevators. Regular maintenance and inspections are key to its long-term effectiveness.
