Door Dampers

ACE has high-performance, durable door dampers available to protect elevator doors and other automatically operated or manual door systems from damaging contact. The single or double-sided hydraulic shock absorbers are characterised by their good adjustment capacity and maximum energy absorption between 75 and 190 Nm/Cycle.

The adjustment setting is made for each side independently by turning the retracted piston rod on the knurled head to the required damping force. The possible impact velocity for the door can be between 0.1 and 2 m/s, and the dampers manage up to 10 strokes per minute. Typical of ACE: various characteristic curves, special lengths or customised seals available on request.
