I had the misfortune of having to run one of these Sany excavators for a week and I can tell you up front it was a typical made in China piece of crap! State of the art... yea OK, I guess as long as your idea of state of the art is operating something built with the cheapest iron, cheapest everything possible. The machine spent more time being diagnosed for one issue after another than it did in the dirt, piss poor design did not stop there either, some of the worst response time from operation movement to actuator made for a ridiculous and unfriendly experience! I will take a Cat, Komatsu or even dare I say a John Deere over this crap any day! So please go blow smoke up someone elses ass! Any real operator will tell you this is a worthless piece of shit!

Track slip was horrible, shovel pins were sloppy causing the bucket not to track right and it was fatiguing the eyes. When pulling a stroke you could literally see the top of the bucket deform. About the only good thing it had going for it was it had power, really due to the piss poor quality of the machine itself all that power was tearing it apart! Beyond that though the biggest problem for me as the operator was when I made a motion with one of the joy sticks there was this annoying delay between when I performed the action and when the hydraulics actually kicked in and reciprocated my command. The tracks alone scared the hell out of me and was so poorly engineered had I been told to go work a slope or put it on a slope I would have quit! Just moving the hoe around I watched the tracks and the flex was so bad it looked like they could come off the idlers at any time. This thing was the exact opposite of a John Deere which is over built and under powered, this thing was over powered and under built. For that matter the biggest issue with Komatsu is it to is over powered but at least it is built better than most but they tend to tear themselves apart before they should to.
Chinese steel is poor metallurgy grade and inferior in most applications. We have a much higher standard in steel grade here in the states and typically don't allow for china steel to be used here. It's incredible that we even allow machines made from cheap steel to be imported. Kevin's rant about the machine (having never actually seen one in person myself) who ever allows these imports needs to take a step back and reevaluate the safety on these inferior products.
