When selecting a home elevator, safety is the primary consideration. Unlike commercial passenger lifts operated by trained building managers, residential elevators are operated by family members, children, and elderly parents. Understanding key safety features is essential to keep your family safe.
1. What is an Automatic Rescue Device (ARD)?
An Automatic Rescue Device (ARD) is a smart backup battery system. If power is lost, the ARD instantly activates to lower the cabin to the nearest floor and open the doors, preventing passengers from getting trapped.
2. Electronic Light Curtains
Traditional lift doors use physical sensor strips that require contact to reopen. Electronic light curtains project an invisible grid of infrared beams across the door opening, instantly reversing the door if broken by a hand, child, or pet, preventing finger pinches.
3. Manual Mechanical Descent
If the electrical system fails completely, our hydraulic lifts feature a manual lowering valve. A family member can lower the lift cabin to the ground floor by opening the valve in the control cabinet, ensuring safe egress.
Conclusion
At Crown, we integrate ARD, light curtains, overload sensors, emergency alarms, and manual lower valves into all our models, delivering peace of mind.
