I needed a shingle lift, and there weren't any available to rent in our area, so I made a homemade / DIY one using wood, an electric hoist, chain and a pulley.
I plan on making one of these but instead of mortising out the 2x4’s for the tubing I would weld a piece of flat steel maybe 3” x 6” on both ends of the tubing. Then bolt the flat steel to the 2x4. Same thing for the top pulley tubing.
With such a high frame, you could place it on the gable side and hoist all the way to the ridge to stack your packs there, rather than carrying each pack up the roof.
very nice! I plan something very similar only i am a bit worried about rain. It would be nice to leave this setup for a few weeks or even months, and that standard winch you are using has to go indoors whenever it rains right?
