5500lbs from 6ft in the air, 5ft from where I was standing, PLOP right on the sidewalk.
Nobody hurt, almost all the flagstone on that skid broke into 2 or 3 pieces each and the sidewalk from what I can see didn't even crack. Normally when I unload as soon as I clear the truck I start to lower the mat. down to about a foot off the ground as I move it to where it has to go. In this case I was picking up from the front of the truck bed (opposite the base of the crane) picked the skid up high then retracted the boom to clear a tree so I could swing to the side, drop, then extend to put it where it had to go. After I retracted I looked to where it had to go, then looked back at the skid, started to swing, looked again to where it had to go and before I looked back to start to lower PLOP right on the sidewalk, I was parked right beside the sidewalk. About 4500lbs +or- of material + 900lbs for my fork call it 5500lbs altogether. The cable on this crane has a working load rating of 10,000 lbs.
Just think if my foot or a kid ???
I hate unloading when people are around, kids that are running around loose, I just stop and say stand over there, or tell the parents keep them out of the way far away, usually works. The worst is the guy who wants to help, he just gets in the way and slows me down, plus he doesn't know the danger zones. Standing under the material is obvious, but standing between the material and the base of the crane is just as bad. There are 2 cables on my crane 1 for up + down, the other for extend + retract you stand in between the mat. and the base that cable snaps whatever is on the hook slides down towards you, PLOP.
:added: The crane I run is a telescopic one.
I guess what I'm trying too say here is you can never ever be too careful, after today I think I'll take an extra step back away from where I think I should be.
