I'm looking for a block and tackle, with at least a 10:1 ratio, that is made for human hoisting. Most of the ones I found for sale say "not for human support". Any ideas would be appreciated!
A "approved" bosun's chair tackle assembly must have, among many other requirements, a minimum breaking strength of 5,000 pounds.
Look under professional window cleaningequipment.
