Yeah, that mechanism probably gets and 4 rolls to the gallon. Bullet resistant glazing I'm guessing.
I guess when they design the components, the car's interior space is lessened due to the extra thicknesses. Probably why most armored cars are larger models to begin with, to accommodate that. Cool picture.
No kidding! I have a side window off a scrapped Brinks armored truck, that I've been saving for a future ammo test. It isn't even as big as that one, but it probably weighs about 30 lbs.
If they add a counterbalance of some kind(spring, gas shock, whatever), the original regulator works just dandy. You might want it to stay up in a situation, anyway.
that looks like a composite to me, the company I work for installs bullet BRG in banks and pharmacy's and on the edge you can see 4 distinct layers that can stop .308 all day long. This I am sure is .gov only and maybe lighter weight
At a wild guess it's either polycarbonate ("Plexiglas" is one of the most common trade names) or a sandwich with glass layers on the outside and polycarbonate in the middle.
Polycarbonate plastic is very tough stuff when it's fresh. I fully believe those layers would stop handgun bullets, but maybe not rifle bullets. A few years of exposure to ultraviolet light weaken it, though. It has to be changed out every few years, sort of like Kevlar.

Hand crank
ReplyDeleteDoesn't do much good if it's not rolled up....
ReplyDeleteThe people that ride in them don't need to stop and roll it down to toss a coin into the toll basket.

ReplyDeleteI seriously, seriously doubt a 308 would penetrate that.
