GRAY Brand Model 100 PORTAMATIC Air Powered Pneumatic End Lift Jack. I have three available - Price of $400 each.
This is a end lift style jack which operates off a compressed air supply from any air compressor.
LIFT HEIGHT: 36 inches
LIFT POINTS SPREAD WIDTH: 22 to 50 inches
LIFT CAPACITY: 5000 Pounds
Clean - Tested and Ready to Go.
These are out of an old auto service shop but seem to function as new. I have found other brands that are similar selling new for $2,200. With that said Gray Manufacturing, St Joseph MO. is still in business but they don't make this particular model anymore.
These are in Dodge City. Call or email (Mitch) if you have additional questions or want to look at them.
I also have a few other used end lift air jack models. Bushman Model 410 and two COATS S50 lifts.
