Brought 2 new Mack CH trucks to work that forest ran them 24/7 for 6 years. Only shutdown for servicing. Managed to still have the same engine blocks, gearboxes and diffs on both. Couple inframes done but never had an engine blow up. I ran them on delo 400 and serviced them every 250 hours not kms. Hour meters were almost 50,000 hours when we retired them from the bush.
Almost no mention of the Tri Axle, triple drive tractor. All three would need to be driven for fully loaded off road work. I lost my pleasure with Roadranger boxes after driving over termite mounds on long private roads to WA mines. These mounds were more than a metre high and hard as concrete, the front axle bulldozed them flat. The distances were huge and if you wanted to be home that night you had to keep moving, this also helped keep the dust behind you. Only the full harness seatbelts kept me in my seat but the gearbox often got chucked into neutral. Trying to figure out what gear you had been in with everything jumping round was a pain. All bolts in the truck needed checking or tightening. The red grit could carve out brake drums and shoes in a few days.
Interesting that both drivers shown used the clutch for every shift. I know that Eaton advocate using the clutch and here in Oz it must be used when going for a license, but the general consensus among drivers is to slip the lever through sans clutch.
(From and article testing a c509 double) I believe it's to reduce the load on the drivetrain, especially on gravel roads, gradients etc. From memory GCM is about 150t. (There are triples rated to 200t+).
Here in the US it's more common to float the gears, (no clutch) that's how I drive them but I'm just a truck mechanic that drives occasionally. Most new OTR trucks here are auto shift so jammin gears is becoming a lost art to point & shoot rigs.
Easy on smooth highway to any old bugger like me who learnt to drive on 4 speed crash boxes with crash 2 speed axles.. Ratios wide apart so high revs to synchronise.
Fletcher purchased 100 K.W's for $1million, they were carting from Kaingaroa to T.P.P. Kawerau .. An Whirinaki .. If my memory serves me right they were orange an green.. The Trucks they had doing the TPP. run had 2engines an carried 100ton plus, loads ... Get this .. They could do 100mph.
10 axles can't haul 170 tons that double what it could handle. Here in Michigan USA were are allowed 160,000 to 164,000 on 11 axles. Yes 13,000 per axle might be a bit light or 18,000 pounds with a 9' "3-meter" spread axle
These forests in New Zealand tended to have private roads, owned by the Forestry organization. While the video is dated as from 2002 and much has changed since that time. The timber is Monterey Pine (Radiata Pine) a USA species of pine tree. That will grow from seedling to harvest within 30 years in New Zealand. Yet the their native USA, would take 50 to 70 years to mature.
@@ChristopherWHerbert I was not referring to what was Legal to Haul .. You claimed a weight double what the axles and tries could actually handle .. Just not possible to haul such loads on tires that small. My Oshkosh M-911 Tank hauler has tandem axles rated for 65,000# but the tires are twice as large. It has 14:00 R 24 dual wheels The tires are 54" tall on 14" rims each
@@simonmaney3438 GCM Gross Combination weight is what the Truck is rated to tow behind it in a addition to what it can carry on the Truck axles. The load the video claimed would break all of the trailer axles and blow out all of the tires. You can't haul double or triple what axles are rated for.
I read an article a while back and they use long developed, specific shift methods due to the high loads and demanding roads (The triples can run over 200t). They don't have to use the clutch, but do because it was better for the application.

Wow started my working life at the woodsman training in kiangara forest I'm now 78 brings back memories
Truly brings back memories, fitted thousands of tyre's on the majority of the off highway unit's, Truly a Bridgestone commercial tyre's only, 😊😊.

Real driver none of this cowboy no clutch driving

Awesome sight to see kaingaroa forest 73 at woodsman school
is that A Peterbilt Brown, at 3.30
Yes, Honeycombe 378SBFA.
Fletcher purchased 100 K.W's for $1million, they were carting from Kaingaroa to T.P.P. Kawerau ..
An Whirinaki ..
If my memory serves me right they were orange an green..
The Trucks they had doing the TPP. run had 2engines an carried 100ton plus, loads ...
Get this ..
They could do 100mph.
I think there was only one twin engine truck. The second engine used to suffer badly in dusty conditions.
Some of those Wagner drivers were bloody rough...
4:59 mistaking a 904 for a 501 😤
They certainly did
Real trucks made for real men!!!
Where's the Whites ..??

It’s 100tonne. Not 170.
NZ truck and driver magazine C509 test: GCM 175 tonnes with 'high load' options (6x4, triaxle semi trailer, 5 axle trailer). Triples are rated 200t +. T&D mag: GITI tyres C509 test).

Old 654 stemm my old truck
Chur this is an old one
Maybe don’t know how to shift without a clutch
