I was just checking the size of the boom cable it calls for 96 feet, but is it 7/16 or 1/2. I read the other posts but it looks like it goes back and fourth.

My M816 is 1/2" rope on the main load hoist (boom).
I can't recall how many feet even though I just re-roped it this summer with anti-rotation wire. I just put as much on the drum as possible (all but two of the grooves full) with the boom in the fully stowed (fully retracted and hook at the point sheaves) position.
The reason I left two grooves empty was that the side edge of the boom extends down far enough to contact the rope in that particular groove, causing it to bind.

I should add that this would only apply to the "Garwood" bed wreckers. The "Austin-Western" bed wreckers would be set-up differently on the drum/boom edge scenario.

Hi,
Just for reference I had posted back in 07' when we had to re-string the M819 after the old wire failed during use. It used 105ft. of 9/16" dia. 6 x 19 fiber core wire rope with a nominal strength of 33,000lbs. It had 9/16" dia. before and the pulleys on the boom and sheave match the wire rope dia. I'm sure you could put a little more length on the drum if you wanted to.
It wasn't that bad of a job. There's a wedge in the drum that holds the wire. We had purchased a 400' reel and one end had a finished termination.
See attached pics of comparison between old and new terminations as well as how the wire rope seats in the pulleys.

M819 is a austin-western crane, so it may be different than the M543 garwood crane.
