Correct, if the hydraulics fail then NOTHING will happen. But if the driver in the cab hits the operating lever then something will happen, as in this case.

Remember recently another identical thing did happen but that driver said he accidentally bumped the operating lever.

Those truck have a  PTO pump on them to work the  hydraulic rams and the driver has to   Engage it .

to make it go up .

[shaggy851]

the taxi would have been sreaming along which goes by bahts per kilometers and not by the usual kilometers per hour speed when foreign tourists are onboard. The speedo is an ornament likely with a picture or the king covering it along with half a dozen amulets, at that point getting to your destination is in buhddas hands, lol. Truck driver standard, high on yaba left the pto engaged with tray in air, likely bypassed or unoperational alarm by some other cowboy, also lol:D

Tell me are you a truck driver if you are like I was that is impossible to happen ok like you say ok 

number 1 the drive forgot to drop it at his last job ok , that is more likely for it to be up .

Because you have to put the p t o  pump  on manually for it to go up I drive those trucks for 15 years.

 

I am not a truck driver though I have worked with Hydraulic systems for 40 years, in this instance I would guess that it was driver error!

There is a vague possibility of a leak having caused it? if a valve bypasses due to "leakage" strange things can happen! as you state you have to "engage" the pump manually to give pressure to the Hydraulic system, to engage the system manually would entail opening a valve - would it not? if this valve was bypassing due to leakage or whatever, the system would be pressurized, also having seen the standard of maintenance on Thai trucks I seriously doubt the system perfect - I could off course be completely wrong!

[MichaelJohn]

I've heard of Hydraulic Bounce before, where bumps in the road cause the bed of a tipper to raise as fluid seeps past the closed (faulty) valve .

I guess the driver was already within and inch or two of the back of the truck before it hit the bridge?!

No you have  engage the PTO before anything will work POT not on then it can't work , it is in possible for it to go up with out the POT  pump turned on .

No hydraulics work with out a pump , you have to understand a pump drives the hydraulic  System and trucks have POT to drive them I had a truck like that for 15 years I should know would you think .

[impulse]

In fairness to the van driver, a safe following distance gives you reaction time and a little bit of difference in braking distance.  If you're at the recommended safe following distance and the truck hits a bridge and stops in a meter or so, all bets are off.  

 

On a city highway, you can't leave enough distance between you and the truck in front of you for this kind of contingency.  If you did, a dozen other cars would be in that space before you could blink.

 

That's not to say he was, but he could have been driving safely and still gotten caught out.  Any of us could.

I doubt it....the hydraulic pump, which runs off the PTO, would need to be engaged....my guess is the truck bin was not lowered, or only partially lowered. Operator error. 

Thats my thoughts. The tray wasnt lowered. Failing hydraulics could be as simple as a leaking seal. Enough force will move it but unlikely considering the angles and weight. My guess is its a combination and could be put down to poor maintenance and negligence.

"As he approached the scene there was a lot of dust and he could not see anything..."

 

So, at this point of course he stops right?

 

Because, if you're driving a minivan with a bunch of people, of course you're not going to just keep driving forward right?

 

Because you can't see what's in front of you and that's really, reeeaallly important right?

 

If you can't outright stop you're going to slow waaay down as safely and as quickly as possible because, what's causing all that dust right?

 

Right?

 

Ahh <deleted> it! Just keep going.

 

So back to the story where of course " ...he smacked into the back of the truck."

 

 

 

 

 

Correct any good driver would slow down hard and then pump your brakes to warn those behind, should be a natural reflex really, no thinking involved, just automatic. Sad isn't it.

[SOTIRIOS]

...will probably be the least of their worries at the end.....

 

...let them go walking in Pattaya especially...or snorkeling...or even checking into any hotel....they will be potentially risking their lives...

 

...oh yeah...forgot to mention 'VIP' vans and buses .....

 

...and hope they keep away from Bridge....Bingo and Dominoes....

I know in the US they also have a lock down lever that locks the bed down, its normally a pretty hard lever to pull and takes considerable force to release.

If a "valve" in the hydraulic system failed it would allow fluid to bypass and and lift the back?

i thought you had to engage the power take off that supplies the hyd pump, also there is a fail safe while the vehicle is moving the PTO is locked out ????

ops sorry we are in Thailand fail safe does not apply or has been bypassed

PTO engaged all the time silly me 

[oldsailor35]

Always something 'Failed' if it is'nt the brakes its the steering, this time its the Hydraulics. Nothing to do with the drivers of course.

I was just wondering, seeing he was asking a question, whether or not there was a word out of place.  He initially asked,

 

Quote > "If a "valve" in the hydraulic system failed it would allow fluid to bypass and and lift the back?  I can see a question here but being worded in this manner it would solicit a different response.  If it read,  " If a "valve" in the hydraulic system failed would it allow fluid to bypass and and lift the back? 

 

This makes more sense, however one should consider the alternatives when noting he ended the initial sentence with a question mark.  Don't know if I'm correct, maybe he'll let us know.

I seen the Sydney one as well it is driver  era that makes the try go up  , impossible to go up for by it self .

Yes but that's Sydney. In Thailand there is no such a thing as 'driver error'

[CGW]

^^ I should have written "could" instead of "would. which I said later - without looking at the system I have no idea, how it operates, given the expertise of Thai specialist mechanics who knows if the system is as built, most Hyd systems are fairly complex and are "fail safe" but they have to be maintained correctly, which can be costly!

An example of cost cutting on a hydraulic system which ended up costing billions!! was the BOP hydraulic system that wouldn't close on the Deepwater Horizon as it had not been maintained to OEM standards - to put it politely!

Would poor maintenance happen here? at least the driver didn't do a runner as is usually the norm!

[spacelord]

The fact that he could not see anything certainly did not cause him to slow down or drive with any sort of caution. Rather, in true Thai fashion he probably said "mai pen rai," closed his eyes, and stepped on the gas!!!

And the truck driver fell asleep and hit the hydraulic switch ------

The car driver behind thought, get out of my way , come on hurry up , smack.

[msg4869]

Most likely operator error

But not as good as the lechie monk story ......

Yup. Just ask hundreds of famalies all over the world that have lost loved ones after hydraulic rams have failed and crushed people while working under them. I personally know of 3 victims. Of course, in thailand the rams would raise on their own when they fail and only the bridges get hurt.

does insurance cover removing  the skid marks off the passenger seats ?

I guess you've never seen a dump truck driving forward and tipping his load at the same time? 

[matador007]

This happens in "1st World" Countries too, like Canada.

The driver was drunk, and somehow blood/breath tests ruled inadmissable.
Probably something similar for both accidents -- lack of training (and drunk).

It's nice to see what superb drivers some TV members are as they assert their superiority over Thai people based on a 4 line translated post from the local press....hard to imagine what it's like to be such a perfect driver..........

 

Maybe you need some lessons then, I have driven everything fro motorcycles to HGV 1 and  coaches all over the world, every bend, every corner, every junction, every other road user and pedestrian equates to a hazard that needs to be recognised evaluated and taken into consideration.

 

Something the idiot drivers over here don't comprehend.

 

Sample of Thai driving thought processes = Oh bugger it's raining, I know, if I go faster with no lights on I will get home more quickly, oh poo where did that other car with no lights on doing 140 KM in this weather come from. Hello Buddha.

 

And you have the temerity to defend them....................
