Although they are slower, they consume three times more electricity and have higher operating performance than electric elevators, the hydraulically-driven elevators are well known for their smooth movement, braking and starting and low noise characteristics.
The elevators from the FIRST line have a hydraulic control unit from Blain, Germany and have a built-in Anti-Blackout system that is triggered when the power supply fails. In this case they are powered by batteries to the nearest stop and the doors are opened. Batteries are charged during the normal course. They are suitable for elevators with course up to 12 000 mm and for freight elevators with a capacity of several tones. The machine room can be at any stop.
