anti-fall system with double certified cable: breaks cable? The second intervenes, breaks the second cable? The door is locked in the position in which it is, thanks to the parachute of the series. Since 1998 it has never occurred the break of both certified cables.
Limitation of forces: an electronic system adjusts the engine power, maintaining the impact forces within the parameters of safety.
Mechanical safety rib: provides continuos self-test excluding any possibility of uncontrolled failure.
Protection of lever arms: safety and beauty. The levers are designed and positioned as the law requires, are coated to balance into the overhead door.
Durability and manoeuvrability: tested with 20.000 cycles of opening and closing, they didn’t have to undergo interventions of extraordinary maintenance and/or replacement of components.
Wind resistance: certified class 2.
