E-axle family from SAF
Powerful e-axles for heavy-load trac
Towards e-mobility with
SAF-HOLLAND.
Heavy-load trac will be electric,
green and quiet.
The future runs on electricity.
Stricter CO2 legislation and bans on diesel-operated vehicles in inner cities;
in addition, according to Europe-wide directives, new trucks must have signicantly
lower CO2 emissions. By 2050, all trac is supposed to be emission-free.
So there is an urgent need for vehicle manufacturers and eet managers to act.
Electromobility as a technology changer.
Electrication is the game changer and future enabler for the commercial vehicle industry.
This is because electromobility provides emission-free commercial vehicles and sustainable
eco-friendly logistics and transport processes through innovative technologies.
Join us in pushing the electrical transformation.
The electried trailer axles from SAF-HOLLAND prepare heavyload trac for the future.

Advantages at a glance
Lower fuel consumption, fewer CO2 emissions
The e-axle family from SAF uses kinetic energy of the vehicle to generate additional energy that relieves the vehicle and its units on the road. This lowers
fuel consumption and carbon emissions and thus makes a valuable contribu-
tion towards achieving the emission targets
Noise protection through noise reduction
The quiet e-axles reduce the noise of refrigerated trucks and similar vehicles
on the road and reduce noise emissions to below the limits that will apply in
future. This means that SAF TRAKr and TRAKe meet the ever more stringent
noise protection standards for harbours, airports and night or inner-city trac

Reliable compliance with legislation
CO2 reduction, noise reduction, diesel travel bans and other laws to protect in-
ner cities and high-density areas are among an increasing number of challenges facing the world of transport. Electried axles help you meet strict legal
requirements.
Fewer particulates for clean air
Diesel-powered commercial vehicles are among the biggest producers of
particulate matter. The clean electric engines of e-axles signicantly reduce
the particulate and soot emissions of the entire truck. This ensures compliance with nitrogen oxide and particulate limits and simultaneously improves air
quality.
Ecient and future-proof transport processes
The e-axles from SAF-HOLLAND ensure greater availability, eciency and
sustainability: They save fuel, avoid exhaust emissions, and comply with legal
regulations. The generated energy also reduces downtimes considerably.
Another contribution towards resource
conservation: The TRAKr generator is
produced without rare earth metals.

E-axle family from SAF.
Converting movement into energy.
The e-axle family from SAF uses recuperation for energy recovery. This reduces fuel consumption
as well as carbon and particulate emissions and makes commercial vehicles more eco-friendly.
SAF TRAKr: Electrical recuperation.
Generating power on the move.
During braking or acceleration phases, the centrally located highvoltage generator unit of the SAF TRAKr converts the kinetic
energy of the vehicle into electrical energy. This energy is stored
in a Li-ion battery of the proven electrical system from CARRIER/
ADDVOLT – or can supply auxiliary consumers in the trailer such
as cooling units, heaters or hydraulic platforms while the vehicle is moving. The SAF TRAKr is favoured for use in refrigerated
trucks, where the cooling units can be operated in fully electrical
mode.
Generates energy.
For operating a cooling
unit, for example.
SAF TRAKe: Electrical recuperation and traction support.
More power thanks to an additional electric drive.
The SAF TRAKe goes one further: As well as using recuperation
to generate energy, it operates with a more powerful high-voltage
e-machine with a higher output. With this additional power, the
SAF TRAKe helps power the truck and supports the main engine
when the vehicle pulls away and accelerates. Especially in challenging road conditions and on slopes, the SAF TRAKe provides
greater traction and stability for the articulated truck and provides valuable assistance, for example in site trac.
Additional drive.
More traction during
acceleration and when
driving up inclines.
The obtained energy is stored in a Li-ion battery here as well. Depending on the operating mode, the energy can be used to operate units or to support the main engine of the truck.
Saves fuel and
protects the environment.

Increased availability thanks to internal charging.
Charge the battery while driving and avoid expensive downtimes:
The energy generation of the e-axle family from SAF enables the
battery to be charged internally while the vehicle is in operation.
This reduces the downtimes for external charging processes and
increases truck availability. The battery system is utilised perfectly, which provides real added value during daily operations.

derable assistance to the driver, the vehicle and the units in their
everyday work.
The e-axles are not just quiet and emission-free, they are also
economical. This is because they improve vehicle eciency, reduce fuel costs and require less maintenance. State subsidies
provide assistance to those purchasing and retrotting electrical
solutions for trucks. As a result, e-axles pay for themselves after
just a few years of operation – for an optimised TCO for heavy
commercial vehicles.

Even tyre wear.
SAF TRAKr and SAF TRAKe tap the same torque from both tyres. Advantage: even wear makes it easier for eet managers
to plan tyre changes and reduces maintenance costs.

Sustainable power for your transports.
Powerful support for heavy-load trac.
In long-haul trac and urban spaces, on slopes and in demanding road conditions, heavy trucks and trailers receive optimal
support in every setting with the e-axle family from SAF.
That’s because the energy generated by the e-axles is used where
it is generated: It supplies the vehicle and its electrical components with power during the journey, relieves the main motor, and
increases climbing power on challenging routes. Thanks to emis-
sion-free driving, e-axles enable night transports in high-density
urban areas. In short: SAF TRAKr and SAF TRAKe provide sustainable power for your transport processes
A diverse range of possible applications.
SAF TRAKr & SAF TRAKe.
Cooler
Cooling units are operated temporarily in fully electric mode thanks to the recuperation of SAF TRAKr and SAF TRAKe. This safety backup reliably protects
highly sensitive goods during transport.
Silo and tanker
The electrical compressor is powered by the energy of the e-axles and independently of the truck. This saves energy and ensures additional protection
for the liquid transport or bulk goods.
Moving-oor trailers
The hydraulically controlled oor system or moving sliding panel is electrically
operated by SAF TRAKr and SAF TRAKe and helps the driver load goods safely
and without leaving residues.
Trailer with lift gates
Thanks to the electrical drive solution, the electrical pump for hydraulic tailgates (lifting door) is powered by the vehicle without dependence on the axles.
Transportable e-forklift
With the e-axle family from SAF, e-forklifts can be charged during the trip, so
they are ready for use as soon as the vehicle stops.
