Today's technology allows elevators and elevators to be installed where it was not possible before. As a consequence of this technological evolution, we can increasingly see elevators installed in single-family homes that help eliminate architectural barriers.
The probability of being trapped in a lift or elevator inside your own home is very low, but it can happen, as happened this week in Sitges (Barcelona), where a 45-year-old woman was trapped for eight days in the elevator of her home.
According to the news published on (15/01/2010) by elperiodico.com, it seems that “The fault was due to an electrical problem that occurred just at the moment when the woman was in the internal elevator of her home. The fault caused the light to go off, so the device stopped and she was trapped.” For the rescue, the firemen looked for the electrical panel, turned on the light, and called the elevator, which seconds later opened its doors and the woman was able to get out.
We must emphasize that an elevator and a lift are two similar concepts with many similarities but different, although both have the same level of safety (the main difference is the speed and the regulations that govern it).
How to open the doors of a hydraulic lift in case of a breakdown
In hydraulic elevators and lifts , in the event of a power failure, the car descends to the nearest stop by opening the doors, preventing anyone from being trapped inside. This rescue operation is carried out using an emergency battery (located in the control panel) and a 12 V coil (located in the lowering solenoid valve).
This safety measure is not mandatory, but nowadays, practically all hydraulic lifts have this system incorporated as standard due to its low cost. In the case of electric lifts , this device is more expensive financially and consequently its presence is much less than in hydraulic systems.
