We had a 40 ton crane in the front but it was 70' away, only good for around 2,500lbs. It was able to get everything off the house untill the final contact point.
I can get a pic later if you want. I bought a bag of like 200 litle beads for $1.00 Slide the bead on the string and use a slip knot to stop it. The beads are plastic so the break pretty easy and thats good. Used it for years and it really helps to have a big trigger for me.
