5) Attach Quad-Beam™ Diaphragms
Orient a Quad-Beam™ diaphragm so that the front face of the Quad-Beam™ shape faces
toward the Nose of the system as shown in Figure 56. Slide one Diaphragm all the way to
the Backup to ensure the system is able to collapse properly during impact. Once this has
been verified then slide the Diaphragm forward to approximately
36” [915 mm]
in front of
the Backup. Orient and slide all other Quad-Beam™ Diaphragms onto Monorail and
position each approximately as shown in Figure 58.
6) Attach HS Diaphragms
Orient an HS diaphragm so that the square tube faces toward the Nose of the system as
shown in Figure 57. One at a time, slide the HS Diaphragms onto the Monorail and position
each about
36” [915 mm]
forward of the previous Diaphragm as shown in Figure 58.
