 MIL-HDBK-1013/14
8.1.4
Delta Scientific Crash Beam Barrier System
8.1.4.1
Description. Delta Models TT212 and TT212E, shown in Figure 14, are cable-
reinforced, manually or hydraulically operated, bollard-mounted barriers. The beam is
counterbalanced and lifts at one end to allow vehicle access. This system is frequently used for low
impact conditions (when vehicle speed can be limited) and as the interior barrier (after a primary
high impact barrier) for vehicle inspection areas or sally ports. Performance and cost data are
shown in Table 7.
