Looking For Experts in Rigging---just a tad off topic - Page 2

This may only confuse the issue, but something to think about--Considering the strength of a 1" wire rope, I'm not sure it looks beefy enough for that application.

Here's a chart that gives the strength of different sizes of wire rope:Wire Rope Chart

I'm thinking it's meant for manilla rope.

(My experience is limited to operating a couple of different cranes equipped with wire rope much smaller than 1", but blocks that were A LOT bigger than that.)

On edit: I missed Bear's last reply, it being here at the top of page 2. I think I'm kinda confirming what he said though.

If that eye isn't changed I would expect the T rating to be less than one. I would not lift anything over a hundred pounds with that block in it's current condition it is compromised and you or anybody else who uses it is in danger at all times. Not to be a worry wort but anything being lifted with "steel cable" in that rig is an accident waiting to happen looks like a manilla rope rig to me too. On a more positive side it looks like the shaft has been recently replaced or at least worked on/greased and a new cotter pin definitely worth fixing IMO.
Nice find.

if your looking to repair this unit these guys have just about everything for rigging, lifting and towing avalible.

@DWJ playing the lotto, you just lose a buck. it's more like riding a motorcycle, if you do it long enough, you will go down. it is only a matter of time untill it happens. use that block and it could be your life that you lose.

@OP when you have that rigged up and the eye les go it is going to come at you with all the force that was applied to it. so if you have a 9000lb winch and you have the block rigged on a car that you are pulling onto your trailer you have two lengths of rope @9000lbs which would be ok for the rope since the winch manufacture should have ensured that the rope used will be suffecient for the winch in which mounted upon. but now you have 9000 x 2 applied to the block or 18,000lbs. once it has been welded upon, the tempering process is nulified and any strength beyond mild steel is gone. mild steel has aprox 32,000psi tensile strength, so if you have a eye with a cross section of .5x.5 you have a cross section area of .25 in^2 x32,000= 8000lbs of force that it can resist before permanate deformation/destruction. BUT in the senerio we were applying 18000 lbs, so catastrophic failure occures:
best case: it breaks and goes through the rear window of your truck.
worst case: it breaks and goes through the rear window of your truck and your kid is in the cab.

the best use for that block is going to be for your kids tree house. or scrap. i hope this has been informative, it's meant to scare you into understanding what could happen so you know what can happen. any time you are using a force multiplier (power tools, rigging, hydraulics,etc.) there is a inherent risk that most people don't understand untill it's too late. i would perfer you understand the risk and manage it appropiatly to work in a safe manor.
