Lifting slabs with machinery

[Rough Hewn]

If the slabs are wide and thin they could snap. Especially the pith boards.
Can you get a 4x4 forklift on site?

Or make a simple wooden drag sledge ?

Actually these are far better because the ring attachments are keyholes which allow for adjustment.

 

Noting @Rough Hewn's concern about splitting, I wonder because the  bottom tension in the chain puts the board in compression, just like if you pick up  5 bricks between the palms of your hand.

I've used something similar before but now generally use avant and forks. Slabs slide ok if on wedges but i keep meaning to make some plastic/nylon strips the same width as kerf that could be slid in behind cut/wedge and slide the slab on those. I also though about a hand winch on the forks so I can pull slab off if i'm  on my own, if any of that makes sense?

The only issues I've had are if forks are too low and it rocks the log or bad driving!!!

I've never seen the chain set up.

 

we will make something up with ratchet straps and see how long my patience lasts if it's a pita.

I can see ratchet straps being a pain to use. Why not make the triangle out of wirerope, bulldog clamps and keyhole sliders as a trial then buy a suitable length of 7mm chain.

why not make a lifting thing? out of say 5mm stainless sheet or if not strong enough Hardox400 while keeping weight down, you could even build in a manual/toggle clamp
