I did not want to highjack eef7260's thread on wrecking balls. There is a company in Milwaukee, WI that manufactures wrecking balls called Ginnow Equipment. They make them from 2000 - 15000 pounds in 1000 lb increments. I modeled the one I make after their 4000 lb version. A fair-lead can't be used because it limits the ball's swing. You have to use a large chain between the ball and the tire, as a cable will fray. A cable is used between the tire and the hook block. The reason for the tire is to take the shock out of the line. Another tire is used on the truck bed to set the ball in for transport.

This is the 4000 lb model I make.

Would not have been a problem for me , the more info in one place the better.
Did a nice job on your wrecking ball also Applause
You are totally correct about the chain.
I was a bit in hurry and could not find the proper chain so did it with rope for the time being.
Did find the page from Ginnow Equipment also , seems like they are one of last that produce the real size one's.
I could not find any more info on new one's , found a few second hands.

Ken,

"A fair-lead can't be used because it limits the ball's swing."

True statement when utilizing the wrecking ball on a vertical surface such as a building, but perfectly acceptable when breaking up material on a horizontal surface such as concrete already on the ground, hi-way sections or secondary breaking in quarries.

Thanks Eef, Knowing you are a crane guy, I thought you might have been short on time rigging the wrecking ball. That metal 3D is very impressive, and a lot better than plastic. The wrecking balls make nice line tensioners. Teeth Ken
