Zen and the art of Truck Rescue

A recent experience of mine...

On rescuing a truck from a pit at one of my work sites, when a crane could not reach the truck to pull it out.

The Situation:
The truck's rear right tyres were stuck in a pit, and the rear left tyres were lifted off the ground.

__

..it was 1:00 AM...and we had to hurry up...

(All photos by me.)



The underside of the stuck truck as seen from side-front. You can see the sunken right-rear-tyres.

_____________



The left rear tyres can be seen here.

They are lifted off the ground. (As seen from side-front).

____________________



Work begins...A jack is placed on the rear left tyres as shown above and the tyre is lifted slightly. Aim is to add traction under and around these tyres using bricks, before starting the truck engine and accelerating to pull out of the pit.

________



You can see the bricks that have been added under and slightly on the side of the sunken rear-right- tyres....

The bricks will provide the necessary traction (via friction) for the truck to pull out when it is accelerated.

Without these bricks, there will be no traction because the pit has wet, loose mud and nothing else.

______



Adding bricks for support to the tail of the truck, behind the sunken right-rear-tyres. These bricks will provide support when the jack is removed, just before the truck is accelerated out of the pit.

______



The left-rear tyres again, in this picture.

They have managed to touch the ground, thanks to the jack under the right-rear-tyres...

________________



Adding traction to the side of the left-rear-tyres.

(as seen from the side-back of the truck.)

The jack is removed from under the sunken tyre slowly....and...

WE ARE NOW READY TO SWITCH ON THE ENGINE AND PULL OUT OF THE PIT!!!!

__________



The truck pulls out of the pit in the first attempt!


Precautions in such a scenario:

1. The vehicle must be emptied of its payload to reduce its weight.

2. The jack must be provided with a stable base, as shown in photo 3.

3. The jack must be removed from under the sunken tyre before acclerating the truck out of the pit.

4. The tyres must REST on the bricks under the tyres. If the weight of the tyres does not fall on the bricks, there will not be sufficient traction to pull the stranded truck/car etc. out of the pit.

Vikram you are the very first Indian man I ever heard say "we were in a hurry" :o When an Indian man says 2.00pm he means sometime between 2.00 and midnight.
That was some operation there and great pics. luv suz

Hi Suzanne, thanks for the compliments. These photos were difficult to take, my flash was not working properly.

Hmmm...'it was 1 A.M. and we were in a hurry...' you never heard an indian man say it. I see...

Well there's always a first time. Hope it wasn't too much of a shock. Hehe! :-P

That bit about any time between 2.00pm and mid-night came from a dear friend of mine Prend [shortened from Indian]Patel. I only meant it in fun :o I hope you are well Vikram. :)

Oh, Indians are lazy for sure. Absolutely correct!

Hope your day is going fine. Take care Susanne.

lol what a comment on never hearing an Indian say "We were in a hurry".? Anyhoo, I think you're blog's awesome and you are a great writer. Keep up the good work. I definitely think it would do some good for your traffic if you took my advice on Facebook. Especially the first site because you can socialize with all other members and you get a blog in which to add all your sites and whatever you wish. It's a fun place to be for sure.

All the best of luck, my friend. :) Keep in touch! Bonnie
