Load limits and sizes on wooden and hemp rope A-frame lifting gear

lundi 5 octobre 2015

Writing a fantasy and want to lift heavy items on and off a cart - but not near any building. So the answer is an A-frame and ropes and pulleys.

So far so good. Have been googling A-frames and what I've found have almost all been aluminium. Now, that is interesting to see all the ways the ropes are rigged for different jobs, but not helpful for working out how thick the rope and how thick the wood of the frame would have to be, to lift 300lb, or 500lb or 1,000lb at a time.

Also want some idea of the weight of the A-frame itself - as they are carrying it with them.

Any other info on A-frame usage would be appreciated.
