While watching one of those old "Emergency" tv episodes, I saw them
using a hydraulic device similar to a "floor jack", but it's a wedge
shaped device which expands and will separate or lift things. It will
remove a stuck car door, and so on. I could find many uses for that on
the farm. It appears it can be used in any position too, unlike floor or
bottle jacks which will not work when they are used sideways.
Anyone have any idea what such a thing is called?

Y.W. BTW, E! is one of my favorite shows. When
I'm not yelling at the TV. They can read v-fib
with nothing connected to the patient, and they
spray water without extinguishing the fire. Still,
love the show.

That Harbor Freight one is for autobody work, and iiuc not all of that.
It's about 1/8 the size of what the fire department uses to open up car
wrecks. It's manual, not gasoline powered for one thing. But it's
a lot cheaper too and it might work for you.
Although the "jaws of life" ia a tool I have seen used on that show,
which is a POWER device, what they were using in the show yesterday
(ME-TV) was a single MANUAL tool, similar to one of those smaller 3 ton
floor jacks sold almost everywhere, but it had two wedged shaped tips.
As he pumped it, it lifted a large object off a person. It did not have

That's getting closer, but that is NOT the same.
The best way I can explain what they used, would be one of those small
floor jacks, but rather than wheels on the bottom, there was a lower

The "Jaws of Life" was a trademark by Hurst Corp. which was developed and
used in auto racing and crash extrication. It was heavy and vibrated like
heck when run off the gas power pump, which was notoriously hard to start
and required much maintenance. The motor noise and vibration would put
victims into a panic state unless crews were well trained. One could pinch
their finger off between the jaws when the jaws were let down. Later came
electric pumps. It was a major advance over the porta power eq. mentioned.
The porta power stuff was used in the construction industry and adapted by
the fire service. The alligator jaws mentioned were very weak and if not
operated correctly would break during an evolution. Very hard to pump and
cheater bars were used sometimes. The pump had to be operated against a
solid surface such as asphalt. They sometimes wouldn't work if the reservoir
was above the pump. Also short hoses... Would NOT cut through the A pillar
of a car.
Now air bags have become common and useful.
