I was stationed in Germany back in the 70s and we had to replace all of the rubber pads on our Armored Personnel Carriers prior to heading out for maneuvers. to keep them from digging up the roads. They would slide all over a cobblestone street when they were wet.Charles commented that tanks have steel treads; that got my curiosity up.
I remember in the '70s and 80s reading of the complaints from European cities, that NATO tanks were tearing up their streets, roads, farmland, everything, while running manoeuvres. I seem to remember that tanks had to have rubber pads or be moved by transporters. Makes sense.
The pads are made of metal with rubber inserts. When new, the rubber touches the street, but as they wear off , and they wear off rapidly on concrete, they need to be replaced so the steel frames do not hit the road.David; thanks for confirming that. I'm a wee bit confused though. Did you use the rubber on the streets and the steel in the field, and was it the rubber or the steel that was the slipping issue?
I was on a tour bus years ago, when a horse drawn cart crashed into us. The horses' iron shoes couldn't get a grip on the dry cobblestones (never mind wet!) and the heavy cart just drove them into us.
Tough ponies; they just shook it off.
