The hydraulic jack on my crane has two problems:

1) it leaks around the small (pumping) cylinder
2) When I open the valve, it opens too abruptly, so the crane drops
instead of going down slowly, I totally hate this.

So. I would like to buy a replacement jack, preferably something of
"high quality", chrome plated cylinders, made in USA or some such. Are
there any suppliers who sell similar but better jacks?

Igor, you can rebuild yours (just needs a seal or O-ring or two) or you
can simply buy another one from HF. This time, I'd get an air/over/hydraulic
one like this one:

I haven't seen a US manufactured 8 ton long throw jack in many years.


Grant, I need a much smaller 3 ton one (12 inches retracted). Your
jack is for a 2 ton shop crane, whereas my issues are with the truck
crane. I will call HF for a rebuild kit or replacement. I think that
they have one. I definitely do not need air over hydraulic.
