[Public-List] Mast raising rig and shore cart

[Gordon Laco]

I agree with all the prev comments -

What will cause a break in a lifting apparatus is a shock load... Something
as simple as a kink in a tackle or an over-enthusiastic helper.  I would
further suggest that raising an A30 mast short or single handed is best done
only if all other options are legitimately out of reach.

Cheers -
