I currently have a heavy bag mount I built from
4x4 posts to hold up a 100lbs punching bag. It currently has a nice swivel bracket holding it up, which has been working great so far. The only problem here is that sometimes I need the extra space in the garage, and need to take the bag down.
Is there a safe hitch or knot I could use for mounting, hanging, and taking down the bag? I tried using a clove hitch to hold on to the bag, and then a trucker's hitch to raise the bag up into position, and some half-hitches to hold it in place. This doesn't work as well as I'd hoped, as the trucker's hitch sometimes loosens when I hit the bag really hard and send it swinging, so I'm trying to find a better alternative.
Is there a better set of knots/hitches I could use with some 750lbs type IV paracord, or some stronger rope that would fit into the mounting bracket's loop? This current system would be great if the hitch wasn't loosening and posing a safety risk, as it's a real pain to get up on a step ladder and do a one-armed military press of a 100lbs bag to mount it. I've nearly crushed my fingertips twice while doing this.
