Wondering if anyone has a design for a small hive boom.

I have a pickup with an 8 ft flatbed I use for working my hives. I can think of lots of times I need to pull two or three supers to get down to the brood chamber and my back isn't getting any younger. Also could be used for transporting a dozen or so hives.

Sort of a mini Kelly with electric hoist and trolly on a 9 ft boom. Weight is an issue because pickup is only a half ton. Even a 4 ft boom on one side might work.
