Roger, For pulleys with the necessary strength rating, have you looked at the 
pulleys made for off road winches. They are normally referred to as snatch 
blocks, and are rated at 20,000 lbs. The local harbor freight store has them 
for around $30.00 each. A bit more expensive than the hardware store variety, 
but plenty strong for the purpose. I think they are sized for up to 3/8" steel 
cable. I would start with just one for a 50% reduction in force at the winch. 
If that wasn't enough, then install a second one at the top of the lifting 
fixture. That way most any cable in the original size class would be plenty 
strong enough.73Mitch KJ7JA
