I know there were many threads about electronic scales modified for
weighing bee hives, but I do not think i have time to build that many (need
20-30). so to help with my students weighing all my hives daily I thought
perhaps modifying a manual forklift (removing the cable and put in place a
hanging scale that is digital) would be the fastest.

A typical manual forklift would look like this (

0.5-0.6k. This would not require two people to operate so it should
increase efficiency? I just do not know if there is enough resistance on
the slide (lift) to make the weighing not accurate, and also if it is even
possible to add a scale somewhere...

I found the video which shows a device with the ability to weigh... but the
device was home made.

Instead of blindly doing it, I thought it might safer if someone has done
it before? I could use your same models if you had experimented them
already.

For example, I am a bit afraid if a particular model of forklift might not
have a movable cable to which it can be easily removed and put a hanging
scale in its place. Another concern is the lifter has to have very little
resistance against the main base so the weight is accurate.

Thanks for any info.
