Unit Crane & Shovel Corp.


A 1959 UNIT 617 Crane/Dragline and a 1952 UNIT 614 Power Shovel at my Grandpa's place.  From what I can tell the crane is a 6-ton, 1/2 yard model.  Once I get these to my new house I plan on stripping them down, fix any cracks/rust, re-paint, lube, and then dig a small pond with them.  There is also a boom extension hiding in the grass somewhere around there, but I'm not sure what shape it is in.   Should be a good project to last me a couple of years!

Here are some manuals I've stumbled across on the web:


Ha, I finally found a capacity chart for the crane, sort of. It's for a 614, but I think the 617 just has larger tracks.
 Safe working capacities- based on 75% tipping load
 Radius Pounds
 10'14,500 
 12'12,200 
 15' 8,200
 20' 5,700
 25' 4,000
 30' 3,200

Found the other pieces!  Not an extension, as I had originally thought, but a complete boom:

Stumbled across a Craigslist post for an "8 ton crane block", figured I could put it on the dragline to use it as a crane.  Well, it wasn't exactly a crane block, it was an 8 ton snatch block. Got him to come down to $60 since I can probably still use it for some limited pulling, but will keep my eye out for a genuine crane block with hook. Or even just a ball with hook would work for me!  Johnson Blocks model SB8S8BH (Snatch Block, 8 ton, Single 8" sheave, Bronze Bushing, Hook.)
