Picked up this beast for $125. Blackhawk S4 4 ton, believe this model was the "big boy", from what I've found it was made in the 40's maybe 50's. Has an adjustable handle.
Only thing wrong with it is the rear caster, one of them snapped off, and it's not the typical bolt through style. I forgot to get pics of the casters, I'll get some, but it's unique. I found a set on eBay, a little pricey, hopefully I can talk him down, and not pay more for them than I did for the whole jack. Of course theres no parts available really, I think there are seals kits though.
Before I gave it some love, the main shaft was turning with the arm instead of the arm turning on the main shaft, it wasn't very smooth, and the jack was acting irregular.
I got some grease in the main hinge and jacked up and down bunch, tightened up the nuts as they were loose, and lubed all the moving parts. And just like that it works perfect. Takes 6 pumps to go 100% vertical. Everything is relatively tight for an almost 80 year old jack.
It has a super cool feature, it has a light mounted on it? I've never even thought it would be a thing lol, still don't know how the light works or is powered. The lens is beat up but intact. Also a key slot in the release knob? Best I've found is that it locks the knob so no one can release it.
I know some people think people like me are crazy when I say this thing is beatiful, and beats the new stuff any day. I know some of you are right along with me too lol.
Im gonna get it cleaned up and running, put it to work, then someday I'll make it pretty and keep putting it to work.
