My neighbor is doing some landscaping and I offered him help in moving
a few rocks. These vary in weight between 400 and 1000 lbs.

I have a truck, chains, engine hoist (crane), chain puller etc. If I
can lift those rocks, I could just put them on a catr or something, or
just drag.

Ordinarily lifting such things would not be a problem, but I do not
know how I can grab relatively round objects that are without lifting
eyes or corners. I figure that someone must have invented a great way
to grab rocks with just chain and grab hooks. Any ideas?
