Three operator options are available with Nasatka retractable bollards:
• Integrated electric power unit (EPU) based self-contained operator
• Integrated electro-hydraulic power unit (HPU) based self-contained operator
• Remote electro-hydraulic unit (HPU) operator
The bollards will travel to the fully closed and secure position in approximately three to five seconds under normal operating conditions.
The emergency up (EFO) function of the NMSB Model VI brings the barrier to the secure position in approximately 1-3 seconds.
