Jib Crane

[Jeff May]

I need to fabricate a small jib type crane for my trailer.
I have an enclosed trailer and want to mount this crane at the rear doors on one side to help raise and lower items in and out of the trailer.
I want to be able to lift and swing into or out of the trailer. Maximum weight would be 300 to 400 pounds.
The trailer has a 7' height and 7' wide.
I'd like to put about a 5 or 6' arm on it and mount a winch on a trolley.
Just looking for ideas of how to make up the column that swings.
Any other thoughts or ideas would be greatly appreciated.
Many Thanks,

I would just get one of the ones they make for the back corner of a pick up bed.
Something like this

HF has two models of pickup cranes that would work fine for your situation
