Hi James...
This is a Clark IT-60. I've operated everything from a BT electric stocker up to a Wiggins Marina-Bull, as well as backhoes, articulated loaders, skid-steers... and they're all just machines to me, so I'm control-layout adaptable.
If I recall the data plate correctly, this IT-60's rated capacity is 6000lbs at 24" load-center up 96". She'll set a pallet at about 35'. With 14' marine forks, the lift capacity at the end of the forks is substantially lower, especially with the mast tipped forward, but boats typically have the engines mounted in back.
I got this one from a college roommate who owns a marina up in Minnesota... he's giving me the standard 4' material forks and headache rack, too... I even got the parts book, two pumps, two steering rams, and a pile of notes and reciepts... as well as one boat-rack and one man-basket. She leaks everything but coolant, so I'll be working on, and spending money on it, but it'll shift around MOST of the machines that I'd have around... and of course, it'll help me finish building the rolling gantry, which I'll use not only on those heavy loads, but also to lift out the IT-60's mast ram and counterweight, so that I can give her the TLC she needs.
Can't beat the price... I didn't even hafta pay for the fuel to transport. I WILL hafta replace one of Marshall's trailer wheel/tire assemblies... it apparently had a bead unseat, she went flat, and rolled off somewhere at the interchange 10 miles from home, never to be seen or heard-from since.
I've used this lift many times in the last geez... 15 years. Back when I was in college, I made regular weekend trips up to Allen's marina, and helped 'em winterize in the fall, and launch in the spring... we'd do repairs in the summer, and clean up the property in winter. I've probably had 200 operating hours on this very machine already.
And I had it unloaded a whole two minutes before putting it to work shufflin' stuff around. Later in the afternoon, I plopped a big pallet on it, and poked the pallet through one of our new windows, to move a pile of busted concrete out of a construction area. Works great, just leaks alot.
