Hi Ed,
It's been a long time coming but here is a crane I built as promised posted here first.
It has taken a long time and slot of work to get it completed and everything works as it should and load tested etc.
I had built a Jib crane in my last shop that I posted here, but this one was tricky as I only had a ceiling height of 2.45m in my new shop and wanted a longer reach.
The crane is 3.4m span from the pivot point, made of 200/29kgm beam.
The post Is double 100x100x4mm, attached to 2x 150x100x10mm angle with extra plate welded to it.
It is bolted split story house onto the bearers, 6 floor joist, 6 wall studs and 7 upper floor floor joists.
A total of 15x16mm bolts and 7 coach bolts and 4x16mm dynabolts if my memory is right, so it's not going anywhere.[/size]
The beam being only 2.25m from the ground it needed a super low headroom hoist and nothing is available, so I made my own mini one copied from the commercial manufacturers like Kone etc.
I used a 500kg Chinese hoist with a home made rope block the other motor came from a mud mixer from my friend Peter Marr who is a member here.
The hook only hangs down 230mm under the beam and is 2m from the ground, so no chance of running into it even though I'm 1.8 tall.
The hoist has up and down limit switches with rollers, cable, levers etc as well as travel limit switches.
It also has a power point with extra switch work for lights and just for fun a beeper and lazer positioning lights.The beeper/lazer where mainly for the kids as they followed my journey and helped where they could.
The lady across the road makes stickers, so after seeing the work I had put into it we got together and designed the stickers.
It's been years since I posted up a project so I'm a bit rusty.
I was going to do a detailed write up about building the hoist etc as I've taken hundreds of photos, but I'll see if there is much interest in it first before spending days going through all the pictures I took and detailing each part, step and machining operation etc.
