Ok, well big by my standards.
I might need to unload a planer that weights around 40,000lbs. Unknown exact weight, that's just an educated guess. If anything it'll be less, highly doubt it weighs more than 40k.
I'd be doing it with a 1970's P&H 440TC. 40 ton friction truck crane.
The planer is 9' tall, 28' long and 8' wide, again these arent exact, but close enough for our purposes.
The planer should have holes case through the bed so I can run a rod through, using endless slings it should be very easy rigging. And I can move the table of the machine to act as load balancing.
The machine will probably be coming on a step deck, I'm thinking back the trailer up as close to the outriggers as I can, use only a 40' boom and rig the block for a full 80,000 lbs.
I've forgotten the outrigger stance, but I think 12' load center would put the hook about at the center of a trailer. Even if it's a few feet out I've still got plenty of chart, at 15' I got 70k.
I've never picked up anything close to this heavy with this crane. And I'm worried about the clutches and brakes holding. 40,000lbs on 7 parts of line (the block rigged for a full 40 tons), is 5800lbs per line right?
So I'm wondering if picking up 5800lbs on a single part line and seeing if the clutches and brakes hold would be an accurate test?
Lots of words, I hope I didn't lose anyone.
I've attached pictures of a slightly smaller planer so you get an idea of what the machine looks like, a picture of the P&H and a picture of it's load chart.
If you open the image of the load chart in a new tab and zoom in you can read the numbers.
