There’s a valuable lesson in here men in regard to the importance of always ensuring appropriate engineering input into satisfactory load dispersion when establishing mobile cranes.
As per the attached photo’s, this was a nasty incident on a project out at Castle Hill last Friday.
As we’re all aware, “thorough investigation into load dispersion and back-propping requirements is vital when establishing a mobile crane unit on a suspended slab to eliminate any potential for failure of the supporting deck.”
Incident: Friday Morning 26/09/08 – Castle Hill/Sydney Australia
- 9 Day Old 250t Leibherr Crane (never used before)
- $4mill price tag
- Failure of back propping beneath the 200mm thick concrete deck
- Crane support outrigger punches through slab causing crane to lose balance and collapse across the site and onto adjoining property
- Crane balanced in the air for approx 1 hour before entire rig & boom collapse completely across site and rigs falls through to the basement level.
Amazing that no-one was seriously injured or killed.
