Huge screw up. I wonder what gov big wigs are associated with the bidding and construction company responsible.

From the video clip it looks like the hoisting crane is substandard when compared to the weight of the concrete block. By the way, why the hell they allow moving traffic around that lifiging area. They should totally barricade and block or divert the traffic from the area that the boom covers. Let us see who is going to be the scape goat this time.

So that section of the flyover collapsed before being put into operation. In addition to investigating the construction company, how about investigating the BMA itself also.

The crane was incapable of carrying the load it seems, or incapable at certain slew angles. As a Construction Manager in a previous life I had tower and LMC's on my sites. On one site a tower crane company issued me a certificate of load test of a tower crane and when I asked what form the test took said they lifted a test load. So I asked where - off the ground behind the truck carrying the test weights they said.

So I refused to accept the crane until they repeated the test at every 45 degrees rotation. On the 3rd lift as they complained there was a loud bang and the sheave at the trolley broke raining pieces down onto the ground. So in fact the crane was certified safe although it failed a reasonable test. It would be lifting loads high in the air and slewing, had that sheave disintegrated with a heavy beam at height, for example, how many might have been killed as the sudden shock could have broken the slings.

And that was the UK's foremost crane company. I've sent  LMC's back off site because the crane rope looked like a hedgehog, broken strands poking out all round it and that is a HSE infested UK, I suspect, in fact I know having hired cranes here, that Thailand's safety standards and competancy training hardly exist, inspection and mainenance are reactive not pro active. Just take a look at the wire rope slings used on cranes here - rusty, kinked, knotted even, all indicators of the need for recycling instantly and training of operators on what NOT to do to wire rope! But of course chopping up old crane rope to make slings is cheaper than buying properly tested webbing slings or chain clings.

So a crane overturning here is nothing new sadly and such accidents will continue until a proper Safety and Inspection regime is implemented and enforced!
