Default Shop crane

This is the start of a shop crane. The boys and i dug it out some time back and poured the base. 5/8 and 3/4 rebar pined into the bed rock at 4 1/2 feet with 1" anchor bolts . More to follow. Lee from NYS over taxed and under paid.

Default More shop crane

Hope that i have this pix thing done to spec. More photos of the assembly . Mast is made from a piece of seamless 8 inch XH drive pipe. Base is 1" plate, all critical welds are 6010 root and 7018 hot and cap . Other welds on gussets and etc are .o45 gas(co2) dual shield.All welds preheated and interpass temps monitored closely. Pivot pin is 2"4140 PH on a spoolpiece that extends approx 24 inches down into the pipe. The top pivot bearing is an old brass bushing from a BE drill turned to fit and pressed into a steel housing turned out of an other old drill tool. The bottom rollers are also turned from cutoffs from an old drill stem, and brass bushed. All have provisions to be greased. It moves with one hand with 500+ lb on the hook.
The worst part was assembling it with a borrowed hi-jack because the old Hyster threw a wobbly the day before,and the loader was down to my sons. The completed unit was load tested to 2k at 10 feet with no noticeable deflection. It is able to reach 2 lathes, the horizontal mill, the shaper and the horizontal band saw. Things like the 16" 4 jaw and etc are now no problem. One more pix to follow with a coat of primer on it.

Hi Lee,

I merged your two shop crane threads. It's easier to keep things together, don't you think?

Just hit the Reply button when you want to add to the thread.


Thanks

Lee, size your photos at least 800-1000 wide instead of 200.

Thank you for the replies, the corrections are noted, have attempted to correct the errors made out of ignorance. The magnifying glasses should no longer be needed.
As for Jimmy , it is believed that he is some where under a famous stadium,or is it in the Nevada desert? Just ask 99 people and get at least that many different answers.
Here are the photos of the crane in use. That shaft, or chuck would be a real bear by hand. Lee
