The new Actros Construction: The benchmark for construction
The Actros Construction differs from long-distance vehicles above all due to its outstanding robustness and
additional traction. These design features make it suitable
for a wide range of construction applications with many
different body types.
The construction truck for Africa
The Actros Construction offers a number of special features that are
designed to meet the specific requirements of the African markets:
a large-volume air filter with cyclone-type prefilter prevents engine
failure even in very dusty conditions. The reliability of the engine
is guaranteed by high power reserves and by positioning of the air
intake above the cab where there is least dust and where it is protected
against splashwater. Fitted with parabolic springs at front and rear,
the Actros Construction is designed for maximum robustness.
Reliability
The effective air filter system is complemented by a well
adapted cooling system, designed to cope with the high
outside temperatures. The vehicle is protected by a host of
features, including such simple details as the protective
grilles for the front headlamps. The electronic systems in
particular offer maximum protection against breakdown.
For example, the fuel injection quantities are reduced if
there is a risk of the engine overheating. After all, trucks
can earn money only if they are on the move.
Economy
A high level of robustness is a condition for low maintenance and repair costs. In fact, all the technical features
also contribute to economic operation. The powerful
Euro 2 engines impress with their low fuel consumption.
In addition, the ergonomic design of the vehicle permits
more effective working and reduces the risk of operating
errors.
Special features of the Actros Construction
Whether powertrain, chassis, interior or exterior, the
Actros includes many outstanding features that make
it a superior construction vehicle.
•All information and audio systems can be operated via
the multi-function steering wheel.
•The Telligent® brake system ensures short stopping
distances and automatically controls the interaction of
the service brake and wear-free auxiliary brakes for
this purpose.
•The standard hill-holder prevents the vehicle from
rolling back when driving off on uphill gradients.
•The cab convinces through glare-free instruments and
its surfaces are easy to clean.
•The cab suspension is especially reinforced to cope
with bad terrain.
•Vertical exhaust pipes on 8x4 tippers and all concrete
mixers improve the breathing air quality for the driver
and the workers around.
•The standard Telligent® maintenance system permanently monitors oil and coolant levels, based on an individual maintenance plan.
•The fully-electronic Telligent® engine management
system guarantees efficient engine and drive control
and provides protection against engine overheating
and overspeeding, which would otherwise cause
serious damage.

A construction truck for many different uses
The possible applications for the Actros Construction are as numerous as its benefits. That is why individual solutions are being developed in close
­cooperation with a number of selected and qualified body builders.
Rear tippers
3-axle rear tippers are equipped with a tipping body with
a high payload for a maximum bulk cargo capacity of 14 to
16 m3, while 4-axle tippers offer a capacity of up to 18 m3.
An engine output in the range from 230 to 290 kW is
generally sufficient. The vehicles are usually equipped
with an S or M cab. The off-road capabilities are guaranteed by tyres with a rugged tread, increased ground clearance and a steel suspension with overloading capability.
Actros rear tippers also feature, due to well balanced
equipment with stabilizers and adapted springs, a high
level of vehicle stability and powerful hydraulics.
6
Mobile concrete mixers and concrete pumps
Mobile concrete mixers are realised with a 3- to 4-axle
chassis and usually an S cab. Three model variants are
available for transport of ready-mixed concrete: The Actros
3331 B/36/6x4 is suitable for mixing drums up to 7 m3,
the Actros 3240 B/45/8x4 for drums up to 9 m3 and the
Actros 4140 B for capacities up to 10 m3. An engine PTO
provides the power for the mixing drum made of special
steel while driving and during stationary operation.
Truck-mounted concrete pumps and combined pump
mixers are equipped with hydraulically extending beams
according to the respective concrete pumping heights.
Skip and hook loaders
Skip and hook loaders are increasingly being used for
construction tasks. The versatile containers can remain on
the construction site, while the carrying vehicle is able to
drive to the next work location. Skip loaders pick up and
unload the swap containers by means of two telescoping
arms that are swivelled to the rear. Hook loaders need
more space due to the much larger container volume.
Here, the containers are loaded by pulling them onto
the special subframe of the vehicle and are unloaded by
rolling the containers off. Mainly Actros Construction
chassis with 230 to 260 kW and S cab are used for these
vehicles.
Body chassis
The ladder frame with 50 mm hole spacing for mounting
bodies and attachments provides the ideal basis for body
solutions in the construction sector. Reinforced auxiliary
frames are installed for many body types. The optional
engine PTO and a large range of transmission-driven and
independent PTO’s are available to power the body attach­
ments while driving and during stationary operation. The
Programmable Special Module (PSM) provides an electric
or electronic interface to control the power output of the
PTO’s. Body builders are therefore provided with the best
possible technical basis for their individual work on the
Actros Construction from the factory.

Technology you can trust
From the powertrain to the cab, from the electronics to the running gear: the Actros Construction justifies the trust placed in it through many
technical details in all areas.
Cabs
The cab convinces through comfort and a distinctive and
durable design. The full-steel cab structure is characterised by high strength and rigidity (in accordance with
ECE-R29) and complies with the strictest European safety
regulations. Flame retardant materials protect the driver
in the interior, and galvanisation provides long-term corrosion protection for the metal panelling.
The space offered by the S cab is
sufficient for most construction applications. This cab type also permits
maximum possible body length.
The M cab is an even more comfortable variant, offering larger working
space and can be equipped with one
or two beds and more storage space.
An additional third seat is optionally
available.
8
Both cab variants are equipped with a construction-type
air filter and feature a maintenance-free 4-point suspension to minimise vibrations and noise. Anti-slip, robust
entrance steps with flexible, corrosion-resistant steps
ensure that the driver can board the vehicle safely. In the
interior, comfortable working is ensured by the ergonomic
design of the driver’s workplace, the improved heating
and ventilation, electric power windows as well as practical
storage facilities. The driver’s seat is air-suspended and
the passenger’s seat can be folded up to permit better
cross-cab access.
Clutch and gearbox
Most Actros for Africa are equipped as standard with generously dimensioned singleplate dry clutches. Double-plate dry clutches are installed either as standard or optionally
for particular applications. These clutches guarantee the longest possible service life even
under the most difficult conditions. Two well-matched, fully-synchronised 16-speed
gearboxes (G210 or G240) are available, depending on the input torque and application.
Big gear spreads ensure high gradeability in both on-road and off-road operation and low
engine rev at high speeds. An integrated oil cooler is available either as standard or as an
option for the gearbox (N55), depending on the model.
Gearshift
There is a choice of different variants for the gearshift. The Telligent® gearshift, for
example, reduces gear changing work to a minimum. All the driver needs to do is to press
the gear selector forward or back slightly and confirm the gearshift with the clutch pedal.
This excludes the possibility of incorrect gear selection as well as engine overspeeding.
It also protects the powertrain and relieves the load on the driver. A special construction
site gearshift software, e.g. with faster gear changes, is activated if the differential locks
are engaged. The hydraulic double-H gearshift is the classic gearshift variant and is mainly used for
all-wheel drive vehicles. The current gear is displayed in the driver information system (DIS).
Engines
The robust and reliable Euro 2 engines of the Actros offer a combination of power and
low fuel consumption. The engines are based on the proven unit pump technology with
an injection pressure of 1800 bar and electronically controlled plug-in pump for each
cylinder.
Special components protect the engine against breakdown even under difficult operating
conditions. The engine air intake is located above the cab where there is least dust, for
example. In addition, most of the particulate matter is already intercepted by a cyclone-type
prefilter. Another component designed specifically for Africa is the overdimensioned cooling
system, which guarantees cooling even at high outside temperatures and under high loads.

Brakes
The electronically controlled Telligent® brake system
performs intelligent control of the hard-wearing service
brakes and wear-free auxiliary brakes. It detects the
speed at which the brake pedal is activated and precisely
determines the required braking pressure from this
information. This ensures fast response times and shortest
stopping distances. The remaining brake lining thickness is indicated in percent on the display of the driver
information system.
All Actros models are equipped with enclosed disc brakes
or drum brakes. Disc brakes respond uniformly and can be
controlled very precisely. They have a high thermal load
capacity, wear more uniformly and can be replaced faster
and therefore at lower cost. A brake enclosure provides
protection against ingress of sand and dirt, which cause
faster wear. This means the brake pads are best protected
against intrusion of sand, dust, water or mud. Fully-closed
drum brakes are alternatively used for construction site
vehicles subject to extreme operating conditions, particularly for the all-wheel drive variants.
The wear free engine brake, consisting of constant throttle
and exhaust valve brake, offers braking power and safety
reserves and also relieves the load on the wheel brakes
with braking power of up to 40 % of retarder braking power.
Other advantages of the standard Telligent® brake system
10
include load-dependent brake force distribution, an
emergency braking assist function, a deactivatable
antilock brake system (ABS) and anti-slip regulation
(ASR) as well as a hill-holder function.
Axles
Non-driven front axles on the Actros Construction are
straight cast axles – for maximum ground clearance. They
are always equipped with stabilisers and axle links. In
contrast, driven front axles on all-wheel-drive vehicles are
realised as planetary axles with optional differential lock.
On 4-axle vehicles, mechanical axle-load compensation is
activated under conditions with significant axle articulation.
The rear axles are robust and reliable and are designed
for axle loads of up to 13 t (max. 16 t). Depending on
configuration, construction vehicles are equipped with one
or more planetary axles with differential lock. Thanks to
the flat differential housing, they offer a higher ground
clearance than single-ratio hypoid axles and are available
also with different axle ratios.
PTO’s
30 different PTO variants are available for the Actros
with different installation positions, operating speeds
and sense of rotation. A distinction is made between
independent PTO’s (for direct power from the engine)
and transmission-driven PTO’s.
