Uniform matrix of perforations simplifies body mounting
Robust lightweight construction as a basis
Corrosion protection to the last nook and cranny
With its four truck series - Atego, Axor, Actros and Econic - Mercedes-Benz offers an extraordinarily wide range of vehicles for all industries requiring trucks for transport or services. The spectrum of available gross vehicle weights extends from the six-tonne Atego to the heavy-duty, four-axle Actros SLT with a traction weight of 250 tonnes. Everything from a two-axle 4 x 2 to a four-axle 8 x 8 is possible where the drive formula is concerned, and even five-axle variants can be realised by body manufacturers if required.
The backbone of any commercial vehicle is its frame, and good body mounting ability is the decisive factor when it comes to turning a truck chassis into a complete vehicle suited to the intended purpose. Mercedes-Benz chassis are already well prepared for a wide range of weather conditions and a long operating life. Holes predrilled into the frame in a 50-millimetre matrix allow a great deal of scope for the subsequent installation of fuel tanks, the exhaust system and batteries. This means that body manufacturers save time and the corrosion protection is not compromised – ideal conditions for a long truck operating life.
The frame of the Atego: robust with lots of holes
Whether for refrigerated food, trades or furniture transport – the Atego is equal to any requirement in distribution operations as a versatile all-rounder with lots of talents. It also cuts a good figure in the construction sector. Agile, reliable, compact, versatile and practical – the Atego as a 3-way tipper or skip loader is tailor-made for the needs of the building materials industry.
The frame of the Atego was designed specifically for the requirements of the distribution sector. The special feature is its two-piece construction: the front part consists of two angled side members with a Z-section, which make it possible to lower the height at the front. This gives the Atego up to 10.5 t and the 12 t low-frame variant a low cab entry with a single step. At the same time the Z-section creates space for the installation of major assemblies. Naturally the frame is also extremely strong, with no reinforcements or subframes necessary when installing a taillift (load capacity up to 1.5 t). This frame also has the best possible anti-corrosion protection, namely pre-drilled holes. In conjunction with cataphoretic dip priming, they give the Atego frame outstanding rust protection. Thanks to the 50 mm hole matrix, bodies and mounted components such as tanks, the exhaust system and batteries can be installed without drilling extra holes. As a result, bodies can be prefabricated without problems and mounted more rapidly. This means that body manufacturers save time and the corrosion protection is not compromised.
The frame of the Axor: lightweight but strong
Particularly in medium long-distance operations, the Axor excels with its high payload and low kerb weight. Its economy, safety and comfort make it a real professional in this sector. Particularly effectively, concerted weight-reducing measures ensure high payloads.
What is true for the Atego also applies to the Axor, whose frame likewise has an excellent ratio between robustness and payload. The standardised, 50 mm hole matrix is also employed in the weight sector from 18 to 26 tonnes, which usually makes further drilling of holes for mounted bodies and components unnecessary – while leaving the exemplary corrosion protection provided by cataphoretic dip priming uncompromised.
The parallel frame of the Axor ideally meets two fundamental requirements: extreme strength on the one hand, and not a gram of superfluous weight on the other.
The aim of combining robustness with a high payload was achieved by numerous measures which have reduced the kerb weight. The frame has an extremely good body mounting ability, with rapid and easy installation of bodies and mounted components.
The frame of the Actros: robust with the ideal weight
The same applies to the, as the chassis of these two vehicle families are closely related. In addition to its robust, durable and body-friendly construction with a low kerb weight, the Actros chassis has two outstanding characteristics: firstly the integral rear end of the 4x2 and 6x2 semitrailer tractors, and secondly the intelligently conceived frame front-end. All the connections here are bolted, which means that all the components can be easily and inexpensively replaced if repairs are necessary. The front underride guard is also weight-optimised for a further reduction in kerb weight.
More advantages of the Actros frame: three side member thicknesses are available depending on the tonnage, namely 7 mm, 8 mm and 9.5 mm. It also has the same, standardised tapering frame section and 50 mm hole matrix for precise, rationalised body designs and standardised bodies. Many years of outstanding corrosion protection are guaranteed by cataphoretic dip priming. The Actros chassis is available in wheelbase variants from 3300 mm to 6000 mm.
The Actros Low-Liner with a low frame
If it is not payload but volume that counts where optimal cost-effectiveness is concerned, the Low-Liner Actros is the ideal choice. This has much more to offer than just a loading height of 3 metres, for example a purpose-designed powertrain. In conjunction with direct-drive transmissions, the single-ratio HL 6 hypoid axle ensures gratifyingly low fuel consumption.
The frame of the Econic: low entry and body-compatible
As a genuine special-purpose vehicle for municipal, consolidation and distribution operations, the Econic can be configured for the waste disposal sector, fire services, airport ground services, as a tanker, furniture transporter or milk collection vehicle.
The standard, all-round air suspension and the low, body-friendly frame provide the ideal conditions for the Econic to be equipped with various bodies. When it is used as a fire-fighting vehicle, the low frame makes itself particularly noticeable where only a low headroom is available.
The low-frame concept of the Econic has considerable advantages: by virtue of its two-piece construction with the front section heavily cranked downwards, the frame allows a particularly low cab entry. The rear section of the frame ensures maximum flexibility, allowing a shorter body and wheelbase while maintaining a high transport capacity. Or a low body for the same payload and better handling. The small turning circle makes low-speed manoeuvring in narrow, winding alleyways and courtyards easy. Optionally available leading or trailing axles improve manoeuvrability even further.
The frame of the Econic is highly body-compatible, weight-optimised and extremely robust. As no components project beyond the upper frame edge, it is suitable for any kind of body. The 50 mm hole matrix makes tailor-made, cost-effective body solutions possible without the need to drill extra holes. This means that the cataphoretic dip priming – the best corrosion protection currently available - also remains uncompromised in the case of the Econic.
When equipped with a natural gas engine, the Econic is fully prepared for the future – it meets the stringent EEV (Enhanced environmentally friendly vehicle) exhaust emission standard, and therefore the EURO 5 standard. This is due to its innovative, electronic engine management, integral oxidising catalytic converter and the inherent combustion characteristics of natural gas.
