caterpillar 12 grader

Hi, Luke Irons.
As I understand it, Steelweld were the first company outside the mainand U.S, to be granted a license to build Cat products. They built various dozer blades, cable controls and other attachments - - - and Cat 12 graders, most of which were distinguished by having an 'S' in front of the serial #, as in S8Txxxx. Cat eventually bought the company out, as they did with many companies who were either building under license or building their own products using many Cat parts, as with Elphinstone in Tassie.

Maybe EDB can add more to this.

Just my 0.02.

What cross reference I have on the #12 shows the Aussie equivalent of an 8T to be a 94Cxxxx or a 38Exxxx equivalent of the US 70Dxxxx. No mention of a 59T.

thanks guys maybe that 5 is an s so would it be a 9T-11
roughly what years were they built
regards

US built is..
9K 38-45
7T 45-47
8T 47-57

No 9T designation.

Found this, believe it came from edb.

Could be 59T predates Cat take over????

Still digging....
There is a S9T designation for an Aussie 212 grader.
9T1-9T4598 would be 1947 to 1955 production with D311 engine.
#11 would be first year production.

yes that would be it i started doing a litle research on it
thanks for the help
