what is that a tank?

Halftrack

 

[nahmus]

thanks. Always wanted to drive one of those

That yours? NICE

I wish... But a friend in Connecticut had one of these:

that look like a whole lot of fun

Holy understeer, Batman! Does turning the handlebars also brake a track? Or foot pedals? Not sure that front wheel actually is required.

From the biggest to the smallest German halftrack, they all used a sort of Cletrac controlled differential system. Even if the front wheels were to disappear, the vehicle would still steer. Not only the suspension was wonderfully complicated, but each track link had sealed needle roller bearings that had to be greased periodically.

Compared to the US equivalents, which were basically truck chassis with rubber (and steel wire) tracks and very simple suspensions, they are a wonderful example of German over-engineering.

This. M3 is simple like sledgehammer.

I know of one that was in service carrying a drill rig for water wells in Maine until the mid 2010s. They presumably drove it on the road.

they've got some really strange springs in them though
compression-type coil springs made of flat bar stock, you won't find them anywhere else...

Except for in hand garden shears to spread the handles out, they're in those too

but like nothing else lol

Not unusual at all. Google HVSS and VVSS. Another example of American engineering: Simple and it works well enough.

there's like nothing else that uses them though

Wonder why. Heavy? Would seem good for a buggy.

I think they are used where a super high spring rate is needed in a compact package. Probably why we don't see them in light vehicles.

For shears, I suspect they are used because unlike a coil spring, they don't need external guiding features.

I worked with a kid in Alaska that said they still do that

stick their foot in the choker and ride it up that way

wasn't the sharpest kid, but sure was a hard worker
pretty sure he just didn't feel pain

Sure beats trying to hike up and out of those PNW canyons

In a RWD vehicle like that one, is there a benefit in putting chains in the front wheels? Does it help with steering? (that car likely has no front brakes)

Pretty sure thats the Truckee river in Truckee California, thats one in a series of 4-6 pictures.

Maybe also to help keep those gaiters on.

That the original cable car?

The way the people pushing the same shit today talk about these things it's always been clear they don't care about continued progress. They care about disowning the past and claiming credit for doings that weren't theirs just like every commie ever.

Maybe we won't make the same mistake with them the way we did in the 1960s and 70s.
