Evening all,
just finished our second cut of sileage…and I am so totally cream krackered I cannot believe that I could get so tired…
Must be like the Econofreight Tractomas that gazbo refers to…(and welcome gazbo)…that sounded well tired by your description!
I had quite a lot to do with Nicolas over the years, but all with their Necks, modules, and trailers. Not the Tractomas lorries. Very clever engineers indeed, and quick to grasp an opportunity. I think that the Tractomas story started in the late 70s with the KB Berliet cab PH 640 OM 6x4 that went to China, followed almost a decade later with a Renault Premium cab version 8x8 D90. In between those two were the Pelpel cab version that went to Tunisia, a PH 5030 GM 8x8, your Econofreight one, and the Berliet Cab ISTRANS one, (which may still be running).
The largest fleet of Tractomas, (i)? being the South African Rotrans one, commencing in 2005 with four 10x10s, then 8x8s, and yet more 10x10s. They must have approaching 20 in operation now.
There are certainly two in Australia, 8x8s, operated by mining operator LCR. One of my old friends from Mack, who at the time( 2012) was working in Australia was rather sore at loosing out to Nicolas in this deal for two units initially. The specification that was tried was 8x8, 12.5 tonne front axles, tandem bogie rated at 50 tonnes, (25 tonnes each axle), Kessler LT91, the fronts being Kessler LT81, (which could be disengaged to run as an 8x4). Tyre equipment being 1400 R 25 all round, (twins on the bogie). Tractor gvw being 75 tonnes, gross train weight being 535 tonnes with the semi trailer, and two trailers on 17 axles in total.
Power was supplied by a CAT V12 C27, of 27 litres, 890 hp @ 1800/2100 rpm. Torque output @1400 rpm of 4000 Nm Driving through an Allison M8610 six speed auto with TC880 torque converter, and ZF VG2700 transfer box. Road speed was calculated at 50kph loaded, and 65, (ish), empty…but limited to 40kph! The cab used being a right hand drive version of the Renault Kerax, in sleeper form, but pressurised to prevent dust ingress.
This Tractomas was designed and specified for non highway use! Having full ROPS, and FOPS protection built into the 3.50 metre wide , and 10 metre long tractor unit.
It just shows how companies can develop…who back in the early 50s would have thought that engineers who were adapting ex WW2 ex US Army trailers into heavy haulage modules could end up creating such a vehicle…but Nicolas could never ever be accused of having closed minds!
Cheerio for now.
