This is a Cascades knuckleboom, knuckle boom crane. I think it"s a 8,000# but not sure. It has one hydraulic extension section and one manual along with it"s knuckle articulation. Reach is about 25" or so. Don"t know anything else other than it did work when last used three years ago. The truck is being sold separately locally but if you want to put in an offer go for it. I"d add a listing if we come to terms. Locally we"re asking $12,500.00 and have several interested parties. If it does go as a complete unit we"ll give the hoses and PTO we took off to go with it but you must install and fill with hydraulic oil. What more can I say, look at the pictures and if you want come see it before you buy. 609 six five eight three 777. We do not paypal so payment is via check, money order, or we do accept credit cards directly over the phone. Pickup is at our shop only unless you arrange for freight in which case we will load either your freight truck or yours. Really don"t know the year of manufacture but ebay required a year so we guessed.
