Why rapid action doors from Aliga-Tor?

Rapid action doors
  • In the industrial environment doors have the task of protecting against external or internal influences such as noise, dirt or drafts.

  • In order to ensure a smooth and fast flow of material, high-speed doors are without alternative. Waiting times are considerably reduced by our vertically opening doors.

  • The high opening and closing speeds and their frequency during operation, cause great stress on the material.

  • These forces must be taken into account in the design. In addition, boundary conditions such as size and installation location can result in considerable demands on the safety and control technology.

Made in Germany
  • All our doors are completely manufactured at our production site in Melle-Gesmold.
Light grid
  • An important unique selling point is the light grid we install (protection class IP67). This component is low-maintenance, safe and easy to install.
Absolute encoder
  • In connection with the absolute encoder, the electronics monitor the closing level of the gate leaf up to a height of 2500 mm.
  • The control system knows at all times at which position the closing edge of the gate leaf is located during gate travel.
  • Persons or objects are reliably detected and collisions are prevented.
Frequenzy converter control
  • The control by a frequency converter relieves the gate mechanics by gentle starting and braking. This extends the service life of the door.
  • Despite the high opening and closing speeds, the electronics ensure low-wear, quiet door operation.
  • Short opening and closing times reduce energy loss and prevent drafts. This enables undisturbed operation.
  • The combination of anti-crash system and flexible end profiles prevents damage and thus downtimes.
  • The rapid action door automatically reinserts itself into the guide rails after a collision, e.g. with an industrial truck.
    Typically, no servicing is required.
