Help me with planning a mount for a ski chairlift?
Hi there, I’m looking for some advice as I think through how I can mount and hang an old Riblet center post ski chair. I don’t have anywhere that I can hang it, as it’s too tall for our front porch, so I was considering building something in our back yard.
Chair is around 100 lbs, and let’s assume up to 500 lbs of human payload, plus a small amount of swinging, maybe up to 15° front and back.
I had 2 ideas:
steel post with a 90° cantilever and 45° support welded in. I’d imagine I would need a base plate and bolt into a concrete footing. Cantilever mount point would be ~3’ from the vertical post. Is this structurally possible?
build what I could only describe as a smaller 6’ x 6’ footprint pergola using 4x4 posts with an additional 4x4 at the center line to mount the chair from. Would need to do additional horizontal supports between the legs, and I think it would need concrete posts unless it had a full square frame as a base to sit directly on the ground. Again, is this structurally sound?
Are either of these reasonable plans for somebody who’s mostly DIY, but I do have friends who do metal fab.
