Testing. A three-bollard system, spaced 3 feet (0.9 m) apart, was tested. A 14,885-
pound (6,766-kg) vehicle traveling at 29 mph (47 kph) penetrated 10.5 feet (3 m).
OMNISEC Magnum Vehicle Barrier
Description. The Magnum barrier, shown in Figure 21, is a self-contained system that
can be operated either manually or hydraulically. It consists of welded-steel members rotating
around a heavy, solid-steel shaft at grade level. Three barrier widths are available: 8-, 10-, and 12-
foot (2.4-, 3-, and 3.66-m). The Magnum requires a 4-foot (1.2-m) excavation for the foundation.
An hydraulic cylinder raises the rotating members through linkages. These barriers are intended for
high impact conditions.
OMNISEC also produces a shallow-mounted [13-inch (33-cm) deep excavation] vehicle
barrier called the Stinger that is hinged in the front. Performance and cost data for both barriers are
shown in Table 11.
