The optimised aerodynamics are just one positive feature of MirrorCam. The camera technology also provides advantages when it comes to the handling and primarily safety of the truck. It makes work easier, both on and off the beaten track, for drivers in construction supplier traffic where there are numerous unloading points.

The absence of the mirrors has, on the one hand, considerably improved all-round visibility. The driver has excellent visibility even diagonally in front of the truck, an angle which would otherwise have been concealed by the mirror housing. And it is no longer possible for the driver to incorrectly adjust the mirror. Because from any perspective, the camera shows the same complete image.

From June 2021, there will be another safety assistance system available for the numerous Arocs model variants: Active Sideguard Assist. The new system no longer just warns the driver about moving cyclists or pedestrians on the co-driver’s side, as is the case with Sideguard Assist, but can also initiate automatic braking at a turning speed of 20 km/h until the vehicle comes to a standstill, should the driver fail to react to the audible warnings. Active Sideguard Assist recognises the need for this intervention from the angle of the steering wheel and, ideally, prevents any collision. Mercedes-Benz Trucks is the first truck manufacturer in the world to introduce such a system with active braking function, thus making its contribution toward further reducing the number of serious injuries or even deaths caused by accidents when vehicles are turning.

The now fifth generation of Active Brake Assist (ABA) should also contribute to even greater safety. The system can now better react to people within speeds of up to 50 km/h thanks to the combination of radar and camera system. This can be a safety advantage, especially when driving in built-up areas. Regardless of whether it’s a stationary vehicle or travelling ahead, or an unprotected road user such as a cyclist or pedestrian: ABA 5 can help to avoid a rear-end collision. If necessary, the safety system can initiate an automatic full-stop braking within the system limits until the vehicle comes to a complete standstill. Important to note here: ABA 5 is an assistance system. It is the driver who continues to have full responsibility for driving the truck safely. In addition to other things, this responsibility includes the driver having full control of the truck at all times and follows the traffic closely.

The Mercedes-Benz Arocs is as individual as the jobs carried out by those in the construction industry. Thanks to the large selection of cabs, efficient engines – closely graded with an output of 175 kW (238 hp) to 460 kW (625 hp) – along with drive variants and wheel configurations, it fulfills different requirement profils. Whether bulk goods, building material supply, ready-mixed concrete or transport of the heaviest construction machinery – the Arocs is equipped to deal with all these tasks and more. The Arocs test vehicles on-site are prime examples of the comprehensive programme available for construction traffic.

It doesn’t always have to be the heaviest-duty design. The engageable front-wheel Hydraulic Auxiliary Drive (HAD) has considerably reduced the workload for all those vehicles that are largely out on the road, however occasionally find themselves on the difficult terrain found in, for example, construction sites and quarries. The Hydraulic Auxiliary Drive (HAD) works at a speed of up to 30 km/h and creates the necessary degree of additional traction to cope, for example, with even the slippery surface of challenging slopes. There is up to 40 kW of additional drive power available per wheel. Compared to a permanent all-wheel drive system, there are advantages here when it comes to cost, weight and consumption. “HAD is suitable for us, because we usually only need maximum traction for a short period. We have around 500 kg more payload per load with the system,” says entrepreneur Doreen Trabert, who is a driver herself. Compared to an engageable all-wheel drive, there is always an advantage of 350 kg.

A literally groundbreaking speciality for arduous tasks is the fluid coupling. A combination of hydraulic start-off clutch and retarder in one shared component, it allows for precise driving and manoeuvring under heavy load and at the lowest of speeds. As a primary retarder, it develops a braking power of 350 kW (476 hp). Together with the up to 475 kW (646 hp) output of the powerful High Performance Engine Brake, the fluid coupling ensures high efficiency. “The automated manual transmission in combination with the fluid coupling makes driving considerably easier,” reports driver David Ewan from Scottish company McIntosh Heavy Logistics.
