Industry Leading Crowd Protection Barriers

Gibraltar’s industry-leading portfolio of perimeter anti-vehicle and personnel control barriers features the G-4000 Series of Drop Arm Barriers. Available in either fixed or portable configurations, both classes of the G-4000 Series are crash rated to halt a wide array of vehicles at a range of speeds. In addition, all drop arm barriers can operate under the user’s chosen operation conditions.

G-4000 Series Fixed Drop Arm Barriers

Gibraltar offers a selection of fixed drop arm barriers that have been both tested and certified to ASTM F2656 and DOS requirements as well as engineered offerings. We offer arms that have been certified to ASTM F2656-07 M50 P1, ASTM F2656-15 M50 P2, and DOS K4 L3.

G-4000 Series Drop Arm Barriers are available in a variety of widths dependent on the access point. The barriers are offered in hydraulic and completely manual options with a counterbalance system. The barrier can also be offered with loss of power options like battery back-up.

G-4033P Portable Drop Arm

Unlike other drop arm barriers in the G-4000 Series, the G-4033P is completely portable and fully deployable in about ten minutes, making the system ideal for festivals and events. Available in multiple configurations – both self-trailered and un-trailered – all G-4033P units are electro-hydraulic and can run off 120V power, a backup battery unit, or a backup generator, perfect for areas with unknown or unreliable power supply. All units are finished with hot-dip galvanized steel and painted to Gibraltar’s standards, but custom color requests are possible.

As with Gibraltar’s fixed-arm barriers, the G-4033P is engineered crash rated and ASTM F2656-07 certified. The portable model is M30 P3 certified to halt a 15,000-pound vehicle traveling at speeds up to 30 mph. In addition, the G-4033P Portable Drop Arm Barrier is listed on the USACE DOD Anti-Ram Vehicle Barriers List and authorized for DOD use.
