To me that 400hp AEC shows the company was out of touch with the trucking community of the day.
A large vehicle like that is aimed at a specific client and in the 60’s it wasn’t road train work, perhaps in the 40’s or 50’s but by the 60’s things were moving more quickly.
Lighter faster trucks with good top speed and yet still able to hook on extra trailers when required.
You’ll note all these cattle trucks are single drive and would have been coupled to far more trailers than their designed GCW permitted but they performed very well.
Dad bought two of those LAD Beavers 2nd hand and the reduction hubs in one had never been serviced. Many operators thought the diff oil went to the hubs too.
Ever bought a genuine 680 oil filter? It’s a stocking and some string, you built your own filter with the spacer washers.
Operators wanted spin on/off filtration, good cooling, Donaldson air cleaners, big fuel tanks etc and Leyland Australia didn’t understand.
Even when the Leyland product was replaced by Macks, it was still only single drive albiet with quad box instead of the 6+1 Leyland offering.
The B61 Mack had much smaller brakes, no power steer, smaller springs, almost identical Hp, similar tare but Mack had a gun sales team and they scored the contracts. They tailored the vehicle to the customer’s needs and for most clients the end result was exactly what they wanted.
As the cattle industry expanded, so too did the transport requirements with double deck trailers now the norm and with trucks that can sit on 100 uphill and down the other side.
A quick Google search will show the most enormous cattle road trains in the Territory all aimed at fast transport. With approx 4 hours before unloading and watering, you can’t afford breakdowns.
Slow old plodders like Rotinoff or Antar are from an earlier era.This is good stuff, Cargo.We have all read bits and bobs in the books about the Oz haulage industry, but your posts bring it into much sharper focus.
Would you say that the 200bhp 4x2 tractor was the standard means of pulling a roadtrain across Australia, in the 1960s? What about sectors other than livestock, mining for instance- surely they wanted more powerful, double-drive tractors, even back then?
From what you say, the main failing of the specification of the British imports (apart from the Oz-specific details like filtration etc.) seems to be the lack of a multi-speed gearbox, with a wide range of ratios. Even an Antar would fly if it had an 18-speed Fuller with an appropriate axle ratio!
I`ve mentioned this before anorak , it seemed mad to put a 200bhp 32 ton artic on the road with a 6 speed box ,it was defeating the object of the higher bhp engines they were developing.My dad drove a mkv mm8 with a 9.6 and 5 speed box in it .Top speed 38 mph ,but it was also pulling a trailer so running at top weight at the time.There were other mm8s in the fleet with the 6 speed box that would top 60 mph .Obviously its not all about speed but i cant understand the logic in offering such combinations.When the AV760 was launched it had a 6 speed box as standard but with the extra power surely a 9 or 13 speed Fuller would have been a better option or even developing their own gearbox .They offered the 9 speed fuller over here but very few were put on the road , i dont know if they were more expensive or just not pushed by the salesmen
