Wednesday, March 26th, 2008

Take a look at this short report on a crane collapse that killed two persons in Miami, Florida… according to the report it is similar to the collapse in New York, so I presume it is another tower crane.

MOM press release on the tower crane collapse

Thursday, February 28th, 2008

Pretty fast response from Ministry of Manpower. Click here for the press release. There’s a large photo of the failed anchors and some basic details.

Can’t resist it… some logical questions on the cause of the collapse:

  • Which anchor failed first? Assuming point A matches anchor 4 (see photo from MOM) so logically anchor 4 failed first… as it is the furthest and subjected to the highest load?
  • If the crane collapsed without any load, does it imply that the material is defective, in particular the portion joining anchor 4 and point A? Bearing in mind that the foundation is intact.
  • When was the crane last inspected? What was the condition? How old is the crane? …

The list can go on… but I would not want to be drawn too far into this! All the best to the investigators.
