Application examples

Safely closed access gates in daycare center thanks to the gate closer DIREKT

Gate closer DIREKT on daycare gate

Access gates must always be reliably closed at this daycare center so that children cannot run out into the street. With the DIREKT, the gate closes automatically after each opening, without any risk of injury from a slamming door, because the closing speed can be adjusted precisely to suit the application.

> To the application example

Gate system in the courtyard of an apartment building securely closed thanks to concealed door closer RTS

Outside gate with tube door closer RTS

The hinged gate of the courtyard should always close on its own. But the door closer should not be visible. Because vandalism or even accidental damage to the door closer could prevent it from closing automatically. The RTS built-in door closer now closes the gate automatically – without attracting attention.

> To the application example

Controlled opening of custom access gate

Exterior gate with hydraulic damper

Suction and high wind loads caused the heavy hinged gate to open practically uncontrollably. Now, two adjustable oil dampers ensure that the gate always opens slowly and is comfortable to operate, even with strong winds.

> To the application example

Entrance sliding gate on a slope – Safety thanks to DICTATOR radial dampers

Access gate with radial damper - view from inside

Sliding driveway gates on slopes are usually equipped with an operator, as they are almost impossible to control by hand. A DICTATOR radial damper works together with the operator and prevents dangerous situations: in the event of failure of the operator: It controls the speed of the gate over the entire travel and ensures secure and slow closing.
