Not longer but I have used a 20' piece with a come along to the
floor to break a nut on the back of a hydraulic cylinder piston. The
cylinder was out of a track hoe and about a 2" thread (it was metric
so I don't remember the exact thread size). Two hefty guy bouncing on
the end didn't break it but the come along did. I've got tie downs
embedded in the floor of my shop which I hooked the come along to. The
rod of the cylinder was held by inserting a piece of shafting the size
of the rod end into the big vise I've got and then chaining the other
end of the shaft to the 5" OD pipe heavy wall pipe shop support that
I've got the big vise mounted on. I probably would of broken the vise
if I'd just relied on it to hold the rod. I was using a 48" Rigid pipe
wrench on the nut.

You just got to love Rigid pipe wrenches . Wonder what it would take to
break a big one ?

It takes a lot but it can be done. I've had to fix more than one in
my time. In fact the 48" I have has 12" of the handle broken off so it
only measures 36".

A while back I had to straighten a nearly brand new 48". They had
hooked it to a winch truck and bent the handle in a rather difficult
to straighten angle. I was rather surprised how soft the handle was.
It bent like butter.
