I am thinking, that when the forklift holds a weight on the forks, the

Does anyone make a product or some such that I can hook into the
hydraulic line somehow, that would tell me the pressure and the weight
of the item being lifted?

Sure, most lift companies sell them. They are a calibrated gauge that
attaches to the lift side of the ram. You pick the item up. Release the
handle and the gauge reads out the weight in pounds/kilos. The mechanical
ones work OK but they are hard to read sometimes.
I like the electronic versions.

Electronic versions with a pressure transducer.

The ones we used at conventions had a little printer that would print out a
tape of serial lifts. *Not very complicated, and I believe wouldn't be very
expensive. *They were the very old pin printers, and you'd hit PRINT and it
would sound like chicken scratching, then spit out a ticket as wide as a
cash register tape. *The unit was four by four by six inches. *Digital
weight readout.

They're out there, they ain't expensive, just find one.

Thanks guys.Those things seem to be expensive.

I am thinking about something simple, such as installing a pressure
gauge on the hydraulic line that lifts the main ram, mounting it where
it is convenient to see. I would then attach a little card with a
table of how pressures match weights, next to the gauge.

If I want to be fancy, I can install an electronic gauge.

That should work pretty easily, no?

Try attaching a gauge to this and calibrating it....
