 The NMSB XII is a 3' deep mounted barrier for high threat security facilities. The NMSB XII is the highest security crash beam available worldwide, certified by the Department of State to stop a 15,000-pound vehicle traveling at 50 mph. The average barrier opening is 16' (4.88 meters). In the secure position the center line of the barrier is 33" (83.8 cm) above the road surface. The NMSB XII can be hydraulically and/or manually, counter-balance operated. The fortified, "sling-shot" concept Drop Arm barrier system design, is an ideal stopping mechanism for maximum perimeter security. After crash impact, the test vehicle was propelled backwards up to 6 ft. Other widths are available, including configurations for bidirectional roads.
Intermediate to High Threat - Drop Arm Barrier:
- Certified to 450,900 foot-pounds-force (15,000 pounds at 30 mph)
- Requires two 36" deep excavations
- 12 thru 24 foot wide traffic lane
- Hot-dip galvanized
- Powered/manual operation
Models Available:
Models XII & XII-a
 The NMSB XII-a Drop Arm - crash beam barrier is for intermediate-threat security facilities. The NMSB XII-a is a choice addition for commercial applications and is crash tested and engineer rated meeting DoS K4 standards to stop a 15,000-pound vehicle traveling at 30 mph.
Drop Arm barrier operation overcomes terrain issues due to snowplows or other roadway obstacles. Its optimal operation as a "sally-port" system to operate in unison with Ross's steel-plate or bollard barriers creates a virtually impenetrable, stoppage and trapping configuration. The standard barrier opening lengths range from 12'-16', 16'-19', and 20'-22'. In the down and secure position the top of the barrier is 33" (83.8 cm) above the road surface. Hot-dip galvanized for years of service. EPA approved self-contained attached housing unit. Drop Arms lower cycle / hour operating systems are best suited for minimal vehicle-traffic, access-control scenarios. Standard barrier deployment time is 8-15 seconds per cycle depending on varying barrier size. Vertical or horizontal open/close options as well as custom sizes and configurations are available.
Applications:
- Remote locations
- Infrequently used points of entry
- Areas with extreme entryway widths
- Areas with an intermediate or high threat security level
- Areas where site excavation for the required installation is not prohibitive
Options:
The following options are added to enhance the performance and operation:
- Hydraulic heater
- Master operator station
- Indicator lights for barrier status
- Traffic signals
- Loop detectors
