The Powertrans ‘powered’ road trains feature a specially designed and built heavy-duty prime mover or tractor unit and up to six trailers with as many as two of the trailers equipped with an identical engine and an Allison transmission as the prime mover.
These massive road trains have been hauling more than 500 tonnes of iron ore at a time over a 52 kilometre haul road between the Fortescue Christmas Creek operation and the company’s Cloudbreak mine and loading facility. In its largest configuration with two powered trailers, four passive trailers and a full load of iron ore, the giant rig, including the prime mover, tips the scales at more than 750 tonnes.
These vehicles have been doing this work reliably and safely in temperatures often exceeding 50 degrees Celsius, largely due to the ability of Allison’s M6610 six-speed automatic to handle the power and torque from the 760 horsepower Cummins QSK19 electronically managed 19-litre turbo diesel engines.

oh now i want to watch Convoy
i havnt seen that movie in years.
I remember as kid on wednesday nights in Ballarat, we would sit in the car with dad while we waited for mum get off work, as the trucks would go past us, we would hang out the window and do the o'l arm impersination and the trucks would all honk back at us.
i dont think they are allowed to do that anymore though
now i know what people mean by the good ol days, to think of the things we missed out on that our parents had seen and done is shame.
love and harmony
