MRT probes the fall of a lifting frame

Metropolitan Rapid Transit Authority (MRT) has launched an investigation to determine how a lifting frame at the construction site of the electric train project fell on two cars and whether the contractor has strictly complied with safety standard.

 

Two cars on in-bound Pahonyothin road near Ratchayothin intersection were damaged and, luckily, the drivers of both cars escaped unhurt. The accident took place at about 3.30 pm.

What is missing in the photograph are the lifting slings....maybe that is the rusty objects just on the left edge of the photo.

The other thing and and I am not an NDT specialist (Non Destructive Testing) it looks like white Magnetic Particle spray is on the lifting eye on the right side 

but the 3 other lifting eyes are very rusty ......so someone has "checked " them - maybe ? But competently ...I very much doubt it.

Further to my last...I now see 3 make shift lifting eyes badly welded to the frame and also the remains of some weld from another that is missing/snapped off.....

So were they lifting with smaller slings and shackles....?

 

more incriminating evidence of deadly overhead lifting operations....

I see 4 well built lifting rings still in place each with 4 gussets to stop rotatiIon by providing lateral restraint.

Here is the website for ItalThai..........http://www.italthaiengineering.com/?lang=en

 

I am sure if you contact them, since you seem to be most competent in this area, they will be pleased to hear your comments about their equipment.

The photos seem to indicate that the frame was being lifted directly above traffic, is that allowed?

It would be a situation any smart person would try to avoid for obvious reasons however i assume on some construction sites this may not always be possible. Whether the lift is occurring within the boundary of the site, or outside, it would generally occur above either construction workers or public areas for some part of time.

 

Lifting equipment design factors of safety are usually extremely high to avoid a situation such as occurred. There is no failure on the lifting "eyes", the cradle appears to have been empty during the fall which suggests either the cradle was not attached correctly, or it was the load being lifted and was not restrained.

Yep. No shackles to be seen so most likely web straps under the frame and it slipped out or they were old and gave way.

But I see no lifting harness. Strange. In an incident like this it is normal to leave the site untouched for the investigation team to view. So where is the lifting tackle?

 

Maybe there wasn't any. Maybe it wasn't being lifted at the time. It could have slipped or been knocked by another force.

Im sure it was just positioned on the ground and that car ran into it causing such impact that it came to rest on the bonnet.

If it fell out because it was just slung with straps then they will still be fixed to whatever was lifting it.

A similar accident happened when they were building the Sukhumvit line back in 1999.

The left hand side extension beam for sliding the concrete section forward dropped down and crushed a taxi cab and killed the cab driver 

 

Then the family of the Taxi driver had to fight the whole way for any insurance compensation and finally the insurance company paid pittance to the family of the Taxi cab driver.

 

It was in the news papers for about 6 months before they finally settled.
