- the complete moving portion including all the mechanism may be simply detached, leaving the base
- the present invention affords a number of advantages over existing powered access control devices and parking posts.
- As the drive means are
- an electronic control reduces the number of separate components required this, both reduces cost and the likelihood of component failure. Also, an electronic control can incorporate a self reversing feature, when the barrier encounters an unexpected obstruction.
