[Shop-talk] air/hydraulic floor jack

[old dirtbeard]

Hi guys,

I did all of my lifting with a standard 2.5 ton floor jack and four jack
stands for decades.

Although I still have a decent hydraulic floor jack that must be close to
thirty years old now, I do have a four-post lift (Backyard Buddy), and
bought some air jacks to use on with the lift (you cannot use a floor jack
very easily with the lift, though I do have center panels for the lift.

I have found, though, that I use the air jacks now on the floor almost
exclusively instead of the floor jack. They go up so easily, quickly,
controllably, etc., with just one finger and you can watch closely as you
position them..

I bought Zendex (all USA made) and they have two heights (a two bag and a
three bag). The two bag jack is ideal for sports cars (it will slide under
my Lotus Elise,), but barely has enough lift for my GMC cargo van where the
three bagger is much better.


I also use the two bagger on my motorcycles:

For close work, like lifting a motorcycle high enough to slide an axle
through the wheel and swing arm, these jacks are terrific.

They are a little heavy and a little pricey, though there are cheaper
Chinese copies out there.

Thay make one on wheels that works like a floor jack as well: I have not
used one, but it looks bulky:

I also have the old fashion chain fall on an I-beam trolley that I still
use often:

And the Backyard Buddy:

And if you have motorcycles, you really need one of these:

For lifting purposes I still use a mix of all of them depending upon what
works best for the particular task at hand.

best,

doug
