I was waiting eagerly for my new piling rig or 'auger' as it is technically called in the civil construction world.assembly started 3 days back,almost complete now.

for people who are not familiar with these terms, well let me put it simply what we were using since some years was the maruti/fiat of the civil world.

but these two pieces of precision engineering are the Mercedes/BMW of the civil world. they work faster,more economical and obviously more costlier than the 'ashok leyland' trucks. they give a work completion rate of almost 3X than the old machines.Both machines are 100% Italian built.

both of them have 'tank treads' which allow better grip on slimy surfaces like mud/slush/loose sand.

I am also attaching a pic of my old machine.

technical specs MAIT - HR 180-

Caterpillar Diesel engine -335 HP (248 KW) @2100 rpm
Mast levelling-4
Hydraulic tank-800 liters / 211 gal
Fuel tank-430 liters / 114 gal
Weight- 57000 Kg - 60000 Kg / 125628 - 132240 Ibs
Nominal torque-233 KNm
Rotary pulldown-180 KN / 40500 Ibs
max WINCH PULLING CAPACITY-164-180 KN / 36900 - 40500 Ibs

the soilmec sm-14 is a smaller machine designed to work where the much bigger mait cannot fit.
the first and the last picture are of the older machine.

Congrats Garrett. Please put light on the assembly aspect of these machines.

Hi tsk,
these machines are shipped from italy in basically 2 containers with the main body.
one container contains all the fittings i.e lights, horns, speakers, footrests,wire-ropes ,lubrication oils ,locking pins and obviously the huge manuals they send u loads and loads of manuals before delivery.

the rotary-boom(the actual thing which does the piling) ,hydraulic motors, hydraulic oil, Calley, Calley bearings, and the carbon/plastic composite pulleys come in the second container.(dont know the exact composition of the pulleys but they take upto 3000kg and are feather light)

basically you have to just go to the site where they are assembling and supervise.
A guy from the respective company comes to the site and the jig-saw puzzle starts, may take 2-3 days for complete fitting and ready for work condition !

will try and get some pics soon.
cheers !

@garrett_t16: What is the actual purpose of these machines?
I have seen huge Bulldozers,etc. This seems to be different.
Are this used for digging holes?
I think I have seen some similar ones during a flyover construction.

Thanks for the info Garrett, would love to see the Work in Progress pics and machine live in action.

[garrett_t16]

@SBK-these machines can do a wide range of things,basically they are used to dig deep cylindrical holes. these holes can be used as a borewell,or it can be filled with concrete to support any kind of REALLY heavy construction(foundation) called rock anchoring ,this explains your spotting during a flyover construction. Many holes(piles as they are generally called) can be drilled touching each other to stop soil movement,land slides which may cause cracks in the buildings surrounding the excavation site(buildings where a basement has to be made)

@TSK-sure will hunt for pictures on my hard disc,will post them asap.

What depths can be achieved with this equipment?
And how do you make a hole, with a rotary bit or something different?

Max dia which can be achieved- 63 inches
max depth-197 feet(with telescopic rotary)

i am attaching a picture of the bit.
we can also use the hammering technique,for that u have to have a pneumatic or hydraulic hammer attachment.

guys here is the video of the machine in action, sorry for the bad quality,
here we were working really close to the sea(i mean really close, approx 100m) so we have to flush out the sea water collected using comressed air before we can introduce the concrete.

so have to keep those raincoats and gumboots handy

That's a very powerful burst. Thanks for sharing.

you are welcome my friend, actually the machine was not pulled to full load as it is new, it was at about 3/4th the total output so you can imagine utilizing the full power

Isn't the generic name Casa Grandes? (Like photocopiers are Xeroxes)

never heard of 'casa grandes' ! would love to learn about it if true.

I was going through the manuals now, while cutting through the rock,the HR-180 exerts 20,000 PSI of pressure

CASAGRANDE - Drilling and Piling Equipment

Got the spelling wrong earlier. Who are the predominant players in this field?

Regards
Sutripta

[garrett_t16]

I had a look at the link, CASAGRANDE seems to be a company manufacturing piling equipment. The thing you mentioned about (Like photocopiers are Xeroxes) it is not like that in this case, the generic name i personally have never heard. They are usually called augers, piling rigs, rotary machines.

the predominant players in this field (manufacturing wise) are -

Caterpillar(many of you might know it only as CAT)
Mait
Soilmec
in India predominantly (ashok leyland)
