For these dampers the name describes them perfectly: They ensure the safety in emergency stop applications.
They are an inexpensive alternative for example on rack operation devices, conveying and crane systems. Use them to avoid expensive damage to machinery.
Safety shock absorbers are maintenance free, self-contained and the majority equipped with an integrated mechanical stop. They have either an integrated membrane accumulator for volume compensation when the piston is in its compressed position or to reset the piston rod.
Or you can select to use a compressed gas accumulator on some models.
ACE offers safety shock absorbers with stroke lengths from 23 up to 1200 mm.
During the deceleration process, the piston rod is driven into the shock absorber. The hydraulic oil, in front of the piston, is forced through a multitude of metering orifices.
The number of metering orifices in action decreases proportionally to the distance travelled through the stroke.
The impact velocity of the moving load is gently reduced!
The internal pressure and thus the reaction force remain essentially constant throughout the complete stroke length.
The oil, forced back by the piston rod is accumulated by the gas accumulator and the compressed gas provides the return force to reset the rod to its extended position.
To separate the hydraulic system from the gas accumulator, a diaphragm is used for the SCS series and a separator piston for the CB series.
