Waiting for it to warm up to start on a gantry crane for my shop , the I-beam I have is 10' long the overall height will be 9' 6". My question is how long do I have to make the base of the legs to be safe? Is 5' enough? I don't want to make them longer than I have to so it will be easy to get around in the shop. But I don't want a crash! Its going to be 1/2 ton cap.
