I am making a davit that is going to be 14' tall. I am probably going to make it out of pipe or 2" square tube. It will be L shaped, the L upside down. There will be a diagonal brace on the top leg of the L. I will use it to mount a hoist. At top, I will put a 1/2" pin to fit into a receiver. On bottom, I was wanting to mount it to a bearing to make it easier to turn, since it needs to move about 270 degrees.
What kind of a bearing would I use? Would it have to have tapered rollers, so that the inside would support the davit, and the outside would be mounted to the base plate?
Or should I just go simple, and mount a couple of big washers face to face and keep them lithium greased?
How would you do it? The davit will weigh what about eighteen feet of two inch square by quarter inch thick steel will weigh, plus a 110 hoist of about thirty pounds, plus the weight of the cargo. So, that much weight would be riding on the bottom swivel point.
