More info
These overspeed governors are set in motion when the levers open by centrifugal force, both in ascents and descents, when the cabin overspeeds. The operation system guarantees that the limiter operation is totally silent as there in no part rubbing on another.

These overspeed governors are valid for setting off instantaneous grip gears with rollers, which are instantaneous with a cushioning and progressive effect.

In descents, overspeeding causes the levers to remain blocked in an interlocking stop designed for that purpose. There is a special device situated on one side of the overspeed governor, which only comes into action in the blocking during ascents. This consists of a rotary lever which is set in motion by the lever of the electric safety device when this is activated by overspeeding during ascent. The special device lever then remains in a position in which one extreme produces a stop at the base of the overspeed governor, and the other interferes with the levers of the overspeed governor as they pass by, thus causing a lock in the ascent.

Associated with the overspeed governor, the assembly counterweight or return pulley should be assembled in such as way as to provide the necessary tension on the cable for the grip gear to work. The return pulley is attached to the lift guide by means of a plate and three flanges, the pulley and the counterweight being suspended from this plate. The electric safety device is also attached to the plate at the bottom, and this will be activated in the event of the overspeed governor cable breaking or loosening.
