This is a addon tool to my truck mounted hay spears. This was built with 2x2x1/4 tubing and some gussets. I also used a 4" pulley and 1/2 plate for the lifting block. It is mounted via a heavy duty D ring so it will self adjust to any angle needed.
I lifted a 1,400 walkie style forklift using these poles and the 8,000 winch.
