Newbie Scratch Build - D575A Dozer

[sparkycuda]

I always perk up when I see a Komatsu machine being built. Yes, the D575A is a monster! Was designed for mining use, but one was used in Nevada by a housing contractor. It had a ripper to break up the caliche (some refer to it as petrified clay) near Las Vegas where no explosives were allowed. It was the only machine that could rip the stuff - ripper tooth would get so hot during use, it glowed, and had to be replaced almost daily. 1150 HP and about 300,000 pounds, 90 cu.yd. blade over 24' wide. Ripper shank almost 7 ft long.

That's for the great ideas !

So had a little machine time the last few weekends:



track profiles turned up so experimented with forming the right bends etc



it needed a little trimming



End result



the gap between the pads was a little too big so had to readjust the jig





these are the ones I will be going with


they need slightly milling at the front so there is a couple mm tolerance but generally they operate well. still need practice on tig as my welds are shocking: )
