Crawlers I photo'd recently.

[Welder Dave]

The guy that put in our cistern had a much newer Hopto on a tandem truck but I think it was a specialty truck like a crane carrier truck rather than a standard tandem truck. He kept it in great shape and pulled his 1 ton flat deck behind it. I looked on the net but couldn't find a similar pic. of it. It was a fairly large excavator. It was very similar to the 300 pictured above but bigger. Maybe a 350 or whatever the next size up was. I'd guess it was late 60's or early 70's.

i "think", they came out with the 360 and the 550. i think the 550 would have been too big to truck mount. my dad's 300 did not have 360 rotation. i think it was like about 300 if i remember correctly.

It looked to be about 3/4yd size but that was back about 1979/80. If a 300 could go on a single axle I'm sure it was bigger. I can't remember it having outriggers but maybe it did. Pretty sure it had 360 rotation. Did some more looking and maybe it was 500. I found info they were 17 ton crawlers but could be truck mounted.

I've seen that loader before. I wonder if it would be hard on the axle's and driveline having a mix of tracks and tires? On a std. loader different size tires can cause damage. With the tracks on the front there could be a big difference in traction too.

WHY???

WHY???

Your guess is as good as mine.

 

[Welder Dave]

Maybe the same reason they put heavy chains on mining loaders? I could see better flotation in soft conditions but big loaders don't work in soft conditions.

Until this jigger came along. Could have been job specific

Here in BC the big pit Loaders run chains on the tires so i if there is wheel slippage tires do not get cut and wreck tires. Our mine on the new 944 has chains on all 4 corners then after a year of so they put the rears on the front. which gives a lot longer tire life.

The caption to that photo implied it was a cat item==don't know.

I reckon it's a early version of Logering VTS track system prior to rubber tracks. Bombardier which became ASV used this system

I'm inexperienced, and I live where soil isn't hard. Typically a loader is diging into virgin earth in a gravel pit, sand pit. I've never understood the need for heavy track loaders. It seemed a rubber tired articulated loader was enough. Other places, Spud Monkey comes to mind, need tracks to dig.

It always seems like the buckets are little compared to the size of the machine.

 

[Welder Dave]

I think the tracks on the front of a loader was something Cat experimented with.

With old photos unless it is corporate with original captions--I don't put much trust in
open comments directly related to photo. A dated corp press release or dated article
in some magazine from that time period is fairly trust worthy. This last week I saw a
reproduction of a 1939 J series Sterling, It was built from parts and pieces of a military
version using a Peterbilt nose originally and the cab wasn't a Sterling either built during
WWII. The reconstruction was a true J series but the base of it wasn't, many parts
hand made. I made a comment about the fact the military version wasn't considered
a J. A group expert came back with a serial number that had a J-C in it saying yes it
was a J series. Problem is The True J Series only had one J in serial number. So what
happens is what's not so correct becomes correct if repeated enough times, and all
is blurred. There are no real J series left in existence, only a made up one.
J Series below.Plus red reconstructed one.

That is one elaborate grill.

In the 1940 movie {They Drive by Night} a "J" series Sterling was used in filming distant shots.
