SDH38 to SDH63

Low reaction forces with long strokes

High Rack Damper, Optimized Characteristic
Energy capacity 3,600 Nm/Cycle to 229,100 Nm/Cycle
Stroke 100 mm to 800 mm

Intelligent protective measure: The safety shock absorbers from the SDH38 to SDH63 series are also designed for emergency-stop applications. Strokes of up to 1,200 mm are possible with these maintenance-free and ready-to-install dampers. Low support forces result due to the large strokes.

The characteristic curve or damping characteristics of all safety shock absorbers from ACE is individually adjusted to the respective application, specific to the customer. The metering orifices for the respective application are specially calculated and produced. These tailor-made machine elements are the ideal protection because they are less expensive than industrial shock absorbers and are effective with up to 1,000 maximum full load emergency cycles possible.

Anyone who wants to reliably protect the end positions of rack operating equipment, conveyor and crane systems, heavy duty applications and test benches chooses these safety shock absorbers from ACE.

ACE safety shock absorbers defy the forces of nature. In order to efficiently protect against falling rocks, a net is put through its paces under realistic conditions. Large sized SDH80-500EU-F type safety shock absorbers with additional crash sleeves safeguard the high durability of the test construction. These models provide the necessary reserves for energy absorption, especially with ...

The aim was to protect a driving simulation capsule on two of its eight axes. The demands placed on a potential emergency stopper were high because it was clear that its failure would lead to massive damage to the complete construction as well as to the capsule. Even the possibility of damage to the health of the test personnel could not be ruled out and was taken into consideration in a ...
