Truck Show Outtake: 2021 Mercedes-Benz Arocs 10×4 – Working In The Sonderklasse Of Concrete Mixer Trucks

2021 MB Arocs 10x4 concrete mixer truck - 1

Well how about that, a late model Benz in one of their classic shades of green! And a heavy-duty dude at that, with its 10×4 drivetrain, operating in the top segment of our concrete mixer trucks. The Arocs is the Mercedes-Benz model for the construction and heavy haulage business.

Historically, the German truck makers Mercedes-Benz and MAN have always had an excellent reputation in the field of heavy on-/off-road trucks and tractors. Factory AWD chassis are available, from 4×4 to 8×8.

Let’s have a closer and thorough look at an impressive piece of the latest machinery. Which brings me to a major advantage of visiting an outdoor truck show: you can take as many pictures as you want without anyone wondering or asking what the heck (or hell) you’re doing.

2021 MB Arocs 10x4 - tandem and steering rearmost axle

Plenty of axle spacing between the rearmost drive axle and the liftable, steering tag axle. Consequently, the tag axle is rated at an axle load of 10 metric tons, which is the maximum for a non-drive axle.

Rearranging these axles must have been an aftermarket job, done by the Veldhuizen company. Mercedes-Benz offers a factory 10×4 chassis for the Dutch market, developed and built by their Custom Tailored Trucks division in Molsheim, France. That chassis is rated at 47 metric tons GVW, whereas the concrete mixer truck at the show is rated at 49 tons (108,027 lbs).
