Cover two differing force ranges: Tandem gas springs by ACE are maintenance-free and ready-to-install. Two pressure tubes deliver different extension forces and progression curves. With this type of gas spring you cover the different force ranges between the start and end of an application. ACE provides free specification support to deliver a gas spring that meets your specific application needs. We manufacture and adjusted precisely to the required dynamics of the application.

A comprehensive range of accessories guarantees easy assembly and a broad range of uses, are specifically suitable for heavy loads with large opening angle. Stainless steel versions are available to meet environmental or appearance requirements.

GST28-40 Lifting of very heavy flaps
Industrial gas springs add support to the muscular strength of the user when opening doors, hoods and covers. Standard models however, which are used for example on vehicle hoods and tailgates, are limited by the functional principle on which they are based. ACE provides industrial tandem gas springs (push type) for large and above all heavy elements, which need to be moved and joined ...
GST28-40 Lifting of heavy flaps
GST28-40 Lifting of heavy flaps
Underground distribution systems are visually advantageous. To facilitate their servicing, the heavy covers of the often large supply systems are brought back to the surface with the help of ACE industrial tandem gas springs (push type). This is quite easily achieved thanks to the use of two pressure pipes, the result of which is two different force ranges. This means fitters must not endure ...

Application Areas

  • Hoods
  • Shutters
  • Machine housing
  • Conveyor systems
  • Folding elements
  • Loading and lifting equipment
Tandem push type gas springs from ACE are used in industrial applications such as in automation and machine building, in the automobile, electronics and furniture industries, but also in medical technology as well as for service hatches.
