    The size of materiel for the upright was not given in that link and ifit was I oppoligize for not reading carefully enough. But yes that is wht I am looking to build. Just not attched to a wall.

    Best of luck on your build. I'm sure if you ask, Don would be forthcoming with the concrete details. He is a good concrete man.

    Verticle column is a W12x36, IIRC. It was left over from a job that was done in '92..bout time I quit hauling that sucker around. I can't complain about how this one came out. It works perfectly on all counts. Picks up and moves my welder skid easily.

    Guess we got lucky Don. Sure would have hated boring those slugs on a 6" Craftsman/Atlas lathe and facing them on a '50s table top mill. Did Jimmie or any of those other Washington boys ever find Pilebuck?

    Nah....I prefer to think of it as a professionally planned and executed exercise. Luck was not a factor.



    Not that I know of, Roy. Creep was posed to get by there maybe. Guess he's been busy.


    My next crane will be a wall mount style.....all I-beam and no cable. Gonna be a one tonner, too. Still 16' out and 12ish high. Not enough room overhead for a cable system. With the reduced capacity, I might see about using sch 80 pipe with 3/8 plate top and bottom for swivels. I found a design somewhere..just need to refind it now. I'll post it on WA one day. No rush on it just now.

    I'd scrap the jib crane idea and build an A-frame, on wheels for mobility, and hang a chain fall from it, use a beam trolly if you want to be fancy. A come-a-long will work if that's what you have.


    You can put car wheels/tires under these for easy mobility in dirt/gravel. If your loads are very heavy (way over what you are considering) you can mount screw down pads to take the weight off the tires, and level the whole thing (that's important if you have a beam trolly, not so important if you don't).
    I've made several of these, you can size them to fit thru the garage/shop door, or you can make telescoping legs so the height will adjust enough to go into/out of your shop. It's basically a free standing/more versatile bridge crane.
    You can build these as large or small as needed.
    Store bought models will give you a very good idea of what size material you need, your capacity is going to be very low so it would be easy to build in a serious safety factor. Run it by an engineer if you have doubts, an hour of an engineers time is pretty cheap if it lets you sleep at night.
    These can be built to handle loads in the hundreds of tons, your application would be very simple.
    Load test the thing to say 125% of your rated load and be happy.
    Never get under a suspended load, and be happy.
    Paint it a groovy color and be happy.

    Keep in mind that if you build one of these mobile A-frames, every body you know that's mechanically inclined will want to use it to: pull engines, dissasymble their backhoe/bobcat, pull their truck bed, skin an elk, hang beef (assuming your friends are cattle rustlers), suspend troublesome teenagers (by the ankles, NOT the neck), ect, ect.
    There is no end to the usefullness of this almost magical device.
    Makes a great place to hang a hammock on those slow days.
    Suspend things for painting, hang that fake (?) skeleton for halloween (or Thangsgiving, if you're like that) I could go on and on but I won't.

    For cost and simplicity, I think JT makes a heck of a lot of sense.

    Don, hit Jimmie up for some pictures of the one he has up at his shop. Looked like it would be just what you need.

    I am not sure off the dimensions of a W12 or W10 beem can some one tell me what I have and if it will work for any part of the crane I want to build please.
    I have it and have never had a use for it so if it will work I might as well use it.

    I have a 25' or 30' beam i picked up at auction 6 or 7 years ago for like $50. the top and bottom flanges are 5" wide 3/8" thick(at the edge the taper to 1/2" thick at the web). The beam is 12" high with a 3/8" thick web.
