Desert specifications

Hello everybody,

I was wondering if komatsu have made bulldozers and crawler excavators with desert specifications and is there anywhere on the web a product guide for dessert spec machines so i can check what the differants are.

I know they made cold weather specs but i can,t find a hot weather dessert spec.

Regards

I know Volvo had, What they called a tropical spec for its excavators, but the only real differance i could see with them was they had air vents in the side panels to allow more air flow around the engine!

Also there loaders had three fan speed settings, with the fast one being for tropical condions!
Im thinking and desert spec machines would have these type of mods plus maybe a reversable fan with wide core radiators etc!

Just my thoughts if it helps any!

Volvo Graders can also be ordererd with a tropical kit. Extra big radiators++.

Regarding Komatsu i have not heard of a tropical kit.(if so, we would have got it)
We have used our PC 210-6 and -7 in 62 degrees C. No problem at all.
Our D65-15 had no problem with heavy work in 45 degrees C.
I dont think they make any tropical kit, their machines is already prepared for high temps.
Of course u got to change oil quality.

Though i know our dozers was delivered with a special type of track guides for the sand. Instead of the regular ones for rock.
Turbo 2 prefilter was also fitted. And we made a snorkel for the D65, to get the intake above the cabin roof. Oil bath prefilter was not recomended.

Our exc was in heavy use in Basrah ,Iraq on the hottest summer ever.

If u get your hands on the parts catalogue, u will find the options and part numbers for the stuff.(if its original)

I must say that the only things I have seen that have offered "tropical specs" are Mercedes Benz and MAN trucks. Cat, maybe, Komatsu, also maybe, but what exactly does it need to fill "Tropical Specs"? More air flow around the engine? More grease? Double air filters?

hello all,

thanks for the information.
every info is welcome.

MKTEF do you have pictures of the modified filters or other examples.




regards,

In this video u can see the conditions in Afghanistan:

This is our D85, it got the same filter as the 65.

The prefilter is a cyclone filter.
For other type of equipment we install oilbath filters, where the producer has one.(we prefer them)
Our scanias also get a cyclone prefilter on top of the airintake.

If u wonder, the dumptruck has its engine turned off in the first video...

As long as you stick to equipment produced for the whole world, you rearly get problems.
Our L150C had motoroil in the hydraulics in Iraq, not the smartest thing when it returned to Norway in winterconditions....

just picture feeding a radiator and cooling fan a steady diet of sandblasting sand at 55mph all day every day.... extra armour fins in the rad, reinforced blade edges... greasing is more to push sand out then lube in...

Alright then, sounds like fun...

Does any body have experiance with sy-klone?

We started using them last year on our wheel loaders, which work in dusty conditions and I am very happy with them, to the extent that I bought four more for our other loaders, generator and grader. They are replacing Donaldson bowls and I am finding that our filters are lasting equally as long, if not a little longer between cleaning. I like the Sy-klone because they are light and of course you don't have to empty the bowl. The important thing to remember, is to match the size of the Sy-klone to the displacement of the engine that it is being fitted to. They can't be too bad, because John Deere and Caterpillar are using them.
