8 This boom was on a Clark Lime
990, The operator (new to the crane) did not know Where to put
the belly band on the off-set jib and boom section, so he
wrapped the Wire rope around the lattice and cords, then when he
installed the back-stay lines he put them on the wrong ears on
the boom and did not have a straight pull on them Note the bend
in both lines on the boom. |

16 My friend looking over his
crane after an accident, he was told a wrong weight Of the piece
he was lifting and told to disregard the load cell in the crane.
Foreman was fired for this. He was reading the wrong blueprint
for the weight of the turbine shell they were lifting. My friend
never got back in a crane after this. Nobody got hurt either in
the accident. This sure would make looking at the carrier
undercarriage easy wouldn’t it? |
