the Western Star has a tridem with planetary hub reduction at the wheels, (like the Oshkosh) -- the other two highway trucks don't. The planetaries, like those on off-road equipment and on heavy trucks throughout Europe and China, multiply the torque at the wheel end by around 3:1. Since the transmission and axle differential ratios are probably close to the same for the three highway tractors, this means that the Star indeed really is pulling more than its share.
You can literally hear the tires on the front truck slowly slipping under the torque. The rubber trails on the road after it passes shows how much power was being transferred to the road. Amazing
For a 8 axle lines combination 3 pulling and one push truck!, so around 2300hp!! How steep is this climb? How much load is it on those 8 axle lines? Could technical not be more than 260t.
Like a Gardner 180 and AEC AV 760 both very torquey both hang on a steep hill without running out of puff, like a good Shire horse.
Ya it takes weight to push or pull weight period, a million horse power is useless without sufficient weight, any way awesome video, and that 4 axle Detroit tractor seems to be really pushing its weight ,cool impressive
