Push-rod system for rail ventilation – Rail mounting configuration

Ventilation flaps arranged across a surface area (several individual or one continuous flap) can be operated by one drive unit on each side. On the rail mountings, LZG gear units are connected to the drive unit by means of a connecting shaft  (1 1/4“ tube – 2“ tube DIN 2440).

The racks move the pull-push rod along the rail mounting and the flap push bar are located on this rod. It is these push bar that actuate the flaps.

  • Up to 40 flaps down the length of each rail mounting, depending on flaps weight.
  • Up to 1500 Nm of drive power can be fed into the system.
  • Load ratings of up to 16000 N per rack unit, and longer strokes or higher load ratings available on request.
  • LZG gear units with various rack heights (Hzd).
