Industrial gas springs from ACE are used to ensure a heavy wooden gate can be driven easily over uneven ground in front of a shelter for asylum seekers. Models of the type GS-40-200 have been integrated into the metal supports of the gate rollers for this. In fact, the gas springs are significantly over-dimensioned for the task as compensating elements. Thanks to the ACE valve technology, sufficient nitrogen could be vented from the cylinders of the industrial gas springs on site in order that these could be configured ideally in the roller construction to the weight of the high-quality wooden gate, and they now function perfectly.
