My son seating opposite me at the dinner table in Austria looked up and said "that is not going to keep the beer cold " the crane had just reversed in.
We used to swing the old "drop Balls" on the end of the Dragline sticks a lot back in early
'60's\'70's.
Demolishing a lot of prewar factory's, Buildings.
GREAT fun.
But look out if you lose control of it.
It can wrap itself round your stick. Or join you in cab.
a coupla ton steel ball out of control is nasty.
Heck of a snatch and a bang when it happens.
Drop it quick. IF you can.
That crane would have a big headache ball, just above the hook
