That's interesting John because a crane/dragline is just what I was thinking about. Draglines I've seen lift a 5 cu yd bucket of sand with a 3/4" cable. Have about 8 trips thru the pulleys. 5 yd bucket at 5k lbs (guess)
5 yds sand @ 4k/yd 20k lbs Total 25k lbs. TSC 3/8 wire rope rated around 2k lbs (just bought some). Area = .108". 3/4 dragline cable is .441" area or 4:1. 2k x 4 is only 8k load rating for cable; load is 25k. But 8 trips is 25/8 = 3.1k. Nice safety factor. Looks like the designers did their job. Hmmmm.
Besides, when I added the block, my arm knew that the winch cable didn't see the whole load cause I could now lift it quite easily whereas before I couldn't and nothing else changed except cable diam and that had nothing to do with what my arm felt.
These things were majestic and must have been 40 yrs old. They'd sit on the side of a sand pit and the operator was so good he made a seamless pattern in the sand, came up with the bucket and dropped it into a dump truck/pup combo and dropped nar a bit on the ground. Now for those uneducated, the pup is about the same size as the bucket that is swinging below the crane and the bucket is swinging towards it; never stops, seamless tapistry...Real artist. Course inside the engine room was clank, clatter, squeak. hummm. I'd bet you were that good. Mark

It's Alright Where It Is! - by Anthony West. I have a tale of a different kind to tell. Whilst rooting in the hedge bottoms this week I had cause to visit Chapel lane Farm, the home of an eccentric gentleman by the name of Austin Kendall. I had heard rumours that an old Case Model C was languishing away in the back of one of the outbuildings there. So off I went in search of what would turn out to be a very rare and unusual tractor. Mr Kendall is an excitable chap to say the least. He is amongst the last of a dying breed of farmer who
