Not a Kboom.....but a step up for us. Brand new national 1300a on a peterbuilt. Been a TON of fun to swing pieces around with this. Small foot print, 110 feet of live boom. 1500lb counterweight makes a HUGE difference.
Bought it...letteted it up....and then got a micro burst in our working area. Talk about immediate reassurance that I made the right decision.
It's been a while since I've posted, but I had to chime in after seeing your post. That is one fine looking outfit! I now have a counterweight also, though the rig was properly set up when I bought it (certified with LMI calibtrated) working at 2 to 4 o clock or 8 to 10 (noon being front) much past 70-75' out my built in sensor in my butt clenched up, it felt unstable, though my LMI said "go a little further, it's cool!" I'm sure it was fine.....just like the bow in the boom of my old Manitex 101S when still well below max, just the way it was. BUT, after noticing the row of threaded holes on the rear of the turret, and then seeing a picture of a 1300 WITH a counter weight, I got educated on the subject.
Wow, now it is rock solid all the way out, at any degree of rotation, it really made this crane a performer. I don't do tree work, but I do everything else, and this thing rocks. SO easy to run smoothly, especially after the older 101S, I had a couple guys up in the manbasket at 140' on a cell tower, between the antennas sort of, and was asked to swing left 12" or 18". With the Manitex I would have laughed out loud on hearing that, I would have had to boom up to get them clear, swing, and then if I was where they wanted boom them back in. With the National (not dissing Manitex, more about how cool pilot controls are I guess) I told them, "sure, no problem," it has such fine and easy to manage controls.
I have been extending my oil change intervals out, the big Mack engine takes 56 frigging qts. to change, but my oil lab tells me to go to 750 hours next time before a change! I was at 400, that looked so good they said go 550, then they said go further! Plus, it doesn't use ANY oil, so far anyway, between changes. I actually asked a pro mechanic if I was reading the dipstick correctly, and sure enough it just doesn't seem to use any oil at all in hundreds of hours. Plus it has a real deep ballsy exhaust sound, unique to the big Macks I'm told. The only thing I don't like so far after well over 1000 hours of operating (and driving, many of my jobs are 1 to 3 hours one way away) this crane/truck combo, is looking at a dogs asshole all day.
