Heavy haulage company Collett have acquired two purpose-built Mercedes-Benz Arocs SLTs, provided by Western Commercials.
Both are 4163 models with BigSpace cabs mounted on steel-sprung 8×4 chassis, and powered by top-rated, 460 kW (625 hp) variants of the advanced OM 473 15.6-litre in-line six cylinder engine. One is plated for operation at 250 tonnes GCW, the other at 180 tonnes.
They feature the Turbo Retarder Clutch, which works in conjunction with the 16-speed Mercedes PowerShift automated trans-mission, in place of the traditional manual gearbox and torque converter clutch set-up.
Geoff Davies, Western Commercial’s Heavy Haulage & SLT Specialist, and an expert on the sector, also supplied Collett with a pair of Actros tractor units – a 120-tonne 2651 model and a 2548 plated at 68 tonnes – earlier this year.
“Our drivers were highly impressed with these fantastic pieces of equipment from Mercedes-Benz,” Collett’s Heavy Lifts Project Director Eric Crosby. “The Turbo Retarder Clutch was particularly impressive, very smooth under load and extremely user-friendly.”
The Arocs are equipped with hydraulic systems and Rockinger couplings front and rear, designed specifically for use with the multi-axled Scheuerle modular trailers on which the boilers were carried. Collett’s fleet of 130 trailers also includes low-loaders and extendable trailers capable of carrying wind turbine blades up to 60 metres long.
Managing Director Dave Collett added: “Heavy haulage can vary so much from one task to the next that you don’t really start to see the whole picture until a vehicle has been in service for a couple of years. In our business, the only way to properly test a truck is on the job, over a long period of time, so that’s what we’ll now be doing with these Mercedes-Benz units.
“We’ll continue to benchmark their performance against our other heavy trucks.On the evidence of this first proper challenge, though, it’s fair to say the early signs are very promising indeed. The Arocs performed superbly and our drivers were full of praise.”
