No it ain't. At least it's not like any Cat chassis I've ever seen.Looks like a big Cat off-road truck.
Ah, but it is. That’s a 798 frame on its way to the oil sands.No it ain't.
You're right. it seems that Cat have adopted the Unit-Rig beam axle design for the front suspension of the 798. I wonder why.?Ah, but it is. That’s a 798 frame on its way to the oil sands.
I had dealings with the older range of Unit-Rigs in Chile about 20 years ago and by f**k they were crude. They also rode like a brick.....I don’t know why, as the rough ride is the only thing I can really pick at on those trucks. They’re absolute beasts.
In my view - why change a design that has worked successfully for the past 50 years and is synonymous with good ride quality by sticking a beam axle under the front of the truck..? It makes no sense.Maybe less machined parts ?
That would be one explanation.Maybe to the beancounters it makes sense.
I was wondering whether the Unit-Rig side of the Cat haul truck operation is being given the responsibility for design of the new range of electric-drive range trucks (794, 796, & 798) and the Cat side is concentrating on the mechanical-drive trucks.? If that's the case I wonder where that leaves the 795AC.?Everything old is new again. Some young engineer thinks he is being clever?
