Was just at the shop today and picked up a length of 1 5/8" unistrut and some hardware to go with the other bits and pieces that I've been collecting. I've got a compressor to change next week. Shipping weight is 185#. I'll have pix.

Originally Posted by jpsmith1cm Work in progress... Typically, I'll tie the rope off to a gas line, unit or something nearby and heavy enough to support the other half of the load.

I'm working on building a frame that can be easily hoisted, assembled, used to raise/lower heavier loads. The big advantage of this would be that same frame could then be moved to the unit and used to move the load in or out of place. Thanks, I like it.

Attachment 393451 Simple arrangement, but it is very effective.

I think it would be better if it was made in round pipe then you have the upright pipe in a hollow pipe. then have a long 90 round pipe in it that way it can swivel out away from the roof then onto the roof to drop the stuff You hold the end of the bar and push it away from the building. The load is brought up away from the building and outside the edge of the roof. Then you bring the ladder back toward the building and the load is on the roof. No dragging/scraping or pulling stuff over the edge.

@walterc is blk for common or extra power?

I rigged up a similar ladder winch some time ago using a come-along. It would work OK as long as you had someone footing the ladder. Otherwise, the ladder had a scary tendency to start "walking away" when you pushed out with little or no load on it. That was the end of my experiment right there.
Developed an android app that does a lot if that counts here

I was mostly looking for a way to lift/hoist the mid-weight items on those buildings that don't have roof hatches. I got lifting through those wired. I have a setup I keep in my garage, block and tackle I think, the rope takes 3 passes through two pulleys, works pretty good.
I made a lift for installing wall mount boilers turns out I use it for all different things.
