Manual assisted-lift retractable bollards incorporate a self-contained pneumatic system to assist the rise of the bollard into place. This pneumatic lift facilitates ease of deployment. It allows for a heavier, more secure bollard to be operated manually.
With the turn of a key, manually assisted bollards easily rise from the ground and can be locked into place. Turn the key again, and with very little effort, the bollard cylinder retracts and locks flush to the ground surface.
Use an automatic retractable bollard system for high-traffic areas.
Appropriate for medium security installations where occasional vehicular traffic must be blocked or allowed access. The retractable assisted-lift security bollard will dependably operate in very cold climates and can be operated occasionally to frequently.
