Below are just some of the more detailed, infamous accidents from around the world!
Worthton, 2005 - A Wolff 320BF( Luffer ) tower crane collapsed into another crane during dismantling.
( 2 Deaths, 1 Injured ).
This "common" practice of loosening / de-torquing mast bolts to "finger" tightness ( or less ) prior to
dismantling and or climbing a crane down, and also during assembly, is still going on to this day!
Germany, 2008 - Liebherr collapse due to bolt de-torque during disassembly.
If anyone knows of other similar tower crane collapses due to mast bolt loosening, please email me details.
USA 2012, Dallas Texas - 2 DEAD
I have been warning about the premature loosening of mast bolts for years!
At least 6 out of 8 bolts were removed from this section alone!
