Default Jib Crane

Ever since I got the mill I quickly found that I needed a jib crane next to the mill to move the mill vise and to lift heavy parts to the mill table. About 3 weeks ago The x & y hand wheels had to be turned 2 complete turns before there any movement. So now I had another reason to have a jib crane, to remove the mill table to work on it. I already had a tall piece of drill stem that held up a beam for my chain hoist, so it became the donor for the jib crane.

For this project I already had materials and since I have thought about is a bit I had a design in my head already, so time to get with it. The difficult part was the drill stem was already in place so no way to do any machining to make slip fit parts.

Used some scrap pipe and drill stem pieces to make the 2 part swivel mounts for the jib and brace. Was not real fun welding everything off a ladder but it all worked out OK.

I was going to mount a boat winch to the drill stem column but them remembered I had a HF 12V electric winch with a remote I got in a trade with my neighbor Bubba a couple years back so out it came, brand new in the box. I did add some grease zerks for the swivel sections so it would spin easily. there is a pic of the table showing it works well.

Very nice.

FWIW, they make (IIRC Gorbel) a "movable jib crane" about the same size & capacity as yours.

It's basically a large base (with trailer jacks each corner for levelling)
Either a box with concrete, or steel plates.

With forklift pockets to move it.

I have seen those. I only have walk in doors so no forklift access and I have gravel floors. I am surprised at how easily the jib swivels under load.

I understand, and yours suits your situation perfectly.

I'm just saying for others, they can copy your design, add a large plate (1/2" thick 3' sq with ribs) and maybe pile cement blocks on it.

At auctions they go for $1 for 20. I have used several of them over the years. Twice I had to buy a new one because I did not have the right size.

The table is back on and the brass nuts are tight. Put a small dab of silicone on the bolts threads so maybe they will not vibrate loose again.
