Definitions

  • the invention relates to a shut-off device for a lane, with a pedestal, with a locking arm arranged on a horizontal drive shaft, which can be pivoted between a horizontal locking position and an upward release position, with a pivoting drive and with an opening movement of the locking arm supporting compensating spring element.
  • shut-off devices for example usable as entry or exit barriers for parking lots, parking garages, etc.
