As we all know, when it comes to government spending, the sky is the limit. So when they are fighting fires, why don't they get about 50 of the Komatsu 575s and put a quick end to it?
kdw75 because that lint of dizer sent across the roads plus the cost of manufacturing and then equipping then fueling then maintaining then disassembly then transport or pay extra for refuel or replace parts of etc etc etc is greater than uncle Sam s current plan
Those monsters are moved around in pieces and assembled on site. A Komatsu would cost at least 4 times a d7. Fire fighting is dangerous, losing that much of your capability in 1 burn over accident would be very bad. 200 machines versus 50..... Heck the roads to get those dozers back to the fire simply do not exist, putting them together and then expecting them to obliterate their own road through perfectly good forest does not make any sense.
Those rigs are difficult to move. They usually have to get broken down and assembled on site by a crew. You can roll and deploy a fully loaded D6 blades and all on a lowboy with some chains. Cant do the same with a 575
It's sucks my old man use to operate one of these old td20 with an open ropes he did it for years at the Victoria bushfires and now there outlawed to open ropes cab
Komatsu 575s are huge and though you think otherwise would take some time to transport. They would have to be dismantled or fitted on a big enough flatbed trailer.
Yep, the D6's can get into tight spots and be transported on ramped lowboys for quick deployment. My state is currently on fire and I've seen CALFIRE QRF roll onscene with the D6 unchained, running and a driver on it, ready to roll. Off the back of the lowboy and up the hill nothing gets in the way.
The weight of a D10T is roughly 65 ton, they could be air lifted to an area and worked, the forest service fire fighting is like everything else this is the way its always been done why change it!!
william davidson not anymore than any other tractor. all dozers go through a crap load of dust. And these dozers have a pre airfilter to prevent embers burning the normal airfilter
that's when the grunts of firefighters come in the handline crews....they are the force that dig handline, not forgetting the hotshot crews that go to the front lines in the wildfires. dozers only do so much and they are slow.
@@hamishcampbell4578 i disagree with you but couldnt find any evidence to suport either argument. So at least in my opinion california is on the leading edge of wildland firefighting.
Wrong mate my old man was at the front line with a dozer making a road with in metres of the fire trying to circle the fire in. Thats in Australia here down in Victoria
look at the vegetation of coarse it is bloody AUSTRALIA, Victoria to be precise the vehicles have CFA insignia and the green PPE overalls are Victorian Dept of ENVIRONMENT staff. If it was NSW RFS they would all be eating or asleep or in front of a camera.
i have known for over a decade never engage a fire with flames over 8 feet high with a hand crew 8 feet and above qith a bulldozer good work ldes safety 1st make sure u have good escape toutes and communications basically good common sense
