Lower life cycle costs
The acquisition costs of investment goods typically make up only a fraction of the total
life cycle costs. Therefore, not only the initial purchase price but also the later operating
costs, useful life and resale value play an important role in investment decisions. Balance
sheet policies must also be considered when developing investment projects. Given
this, one of our basic objectives is to minimize the life cycle costs of our vehicles and to
offer our customers not only vehicle purchasing but also tailor-made leasing models.

Lower operating costs
thanks to low-maintenance and service-friendly design
The VOLK Electric Tow Tractors EFZ
20 N – EFZ 30 N feature a lowmaintenance
design. For example they
are equipped with extremely durable
and practically maintenance-free threephase
asynchronous motors as a
standard feature. All drive systems and
components are arranged in a service-
Longer life thanks to rugged design
The VOLK Electric Tow Tractors EFZ
20 N – EFZ 30 N are very sturdy and
bear up under the hardest strains

solid, cavity-free design. Thus corrosion
caused by moisture penetrating
the frame is almost impossible. Various
Off-balance investment and financial scope

We are pleased to make customized
leasing offers for the VOLK Electric Tow
Tractors EFZ 20 N – EFZ 30 N. This saves
equity capital and credit lines and
preserves liquidity.
friendly manner so that maintenance
work can be completed easily and
efficiently. The traction batteries are
easily accessible and can be optionally
equipped with an Aquamatic system.
This is a central water refilling system
which enables quick and easy refilling
of all battery cells to the correct fill level.
bumper options give the vehicle
reliable damage protection even in the
toughest working conditions. The
standard multi-layer paint and optional
zinc-dipping of the complete
frame guarantee the vehicle’s optimum
protection against corrosion.
Because capitalization on the balance
sheet is effected at the lessor, the
lessee’s balance sheet also remains
”slim“. This means a considerable
increase in flexibility.

Improved ergonomics
Scientific findings prove that optimum working conditions promote employee productivity,
stamina and satisfaction, thus leading to a gain in efficiency. Therefore
designing our products as ergonomically as possible is one of our central objectives.
This was consistently implemented also in the development of the VOLK Electric Tow
Tractors EFZ 20 N – EFZ 30 N.

Multi-adjustable steering column
Spaciously and ergonomically designed driver’s cab
and seat enable fatigue-free continuous operation
An outstanding feature of the VOLK
Electric Tow Tractors EFZ 20 N – EFZ
30 N is the spacious and comfortable
seat and driver’s cab. The roomy cabin
and spaciously designed footwell
enable a relaxed posture. The steering
column is height and tilt adjustable
and thus can be adjusted flexibly to
the height of the respective driver. A
high degree of comfort is provided
by the ergonomically designed,
The driver’s cab of the VOLK Electric
Tow Tractors EFZ 20 N – EFZ 30 N is
equipped with large lateral sliding
windows on the sides as a standard
feature. To improve the fresh air supply
further, the cabin can be additionally
equipped with with a roof hatch. On
request a powerful 2.000 Watt heater
The VOLK Electric Tow Tractors EFZ
20 N – EFZ 30 N are equipped with
hydraulic power steering comprising a
three-phase hydraulic pump. This
allows easy, energy-saving shunting,
multi-adjustable and spring-mounted
driver’s seat. Vibrations acting on the
driver are minimized by the standard
independent wheel suspension with coil
springs on the front axle and the rear
axle mounted on leaf springs. In addition
the entire driver’s cab is mounted
on rubber pads and thus mechanically
isolated from the chassis to reduce
vibration and noise.
Electric heater (2.000 Watts) Independent suspension with coil springs
Comfort thanks to excellent ventilation and
a pleasant temperature in the driver’s cab
provides comfortable temperatures
even on cold winter days. A total
of five fan openings, whose outlet
direction, angle and diameter can be
adjusted individually, ensure that
the hot air is optimally dosed and
distributed in the cab.
Easy maneuvering and concentrated work performance
thanks to hydraulic power steering and clearly arranged
operating elements
even in cramped spaces. Clearly
arranged control elements complete
the user-friendly range of features and
ensure that the driver can perform
his work intently and productively.

Upgrade facility from electric tow tractor to hybrid tow tractor thanks to patented VOLK POWER PACK ® -technology
Higher utilization
During hard daily use two things have always paid off in industrial trucks: a high range in
order to minimize downtimes due to battery changing or battery charging processes and a
high capacity in order to manage transport tasks efficiently. Today it is more important
than ever, particularly with long-term investments, that investment goods can be configured
as needed and used flexibly. Therefore the fulfillment of these requirements is one of our
most important objectives. The VOLK Electric Tow Tractors EFZ 20 N – EFZ 30 N illustrate
this very clearly.

Strategic flexibility thanks to upgrade facility from
electric tow tractor to hybrid tow tractor
The VOLK Electric Tow Tractors EFZ
20 N – EFZ 30 N are designed in such
a way that they can be readily converted
to hybrid tow tractors. All that
is needed is to fit a VOLK POWER
PACK ® unit. This unit comprises a
diesel engine which can be activated
during outdoor operation and which
generates enough power via a
Outstanding performance characteristics and greater range
The VOLK Electric Tow Tractors EFZ
20 N – EFZ 30 N are equipped with
extremely powerful three-phase asynchronous
motors. The outstanding
torque characteristic of these motors
allows dynamic accelerations and high
speeds even with heavy towing loads
or on inclines. To cover even large
distances with ease, the VOLK Electric
Configuration as needed
A wide choice of accessories and
extras enables optimization of the
VOLK Electric Tow Tractors EFZ 20 N –
EFZ 30 N for different requirements.
Hitching of trailers can be facilitated
by various automatic couplings with or
without remote unlocking. Semitrailers
can be shunted with the aid of a
generator to recharge the batteries
while on the move. This results in a
virtually unlimited driving range
depending on the operating profile.
Thus the VOLK Electric Tow Tractors
EFZ 20 N – EFZ 30 N provide you with
a high degree of strategic flexibility
enabling you to react optimally to
changed operating conditions.
Tow Tractors EFZ 20 N – EFZ 30 N
are equipped with batteries with a
capacity of up to 80 V / 600 Ah.
Moreover, the standard regenerative
brake feeds energy back into the
batteries with every braking action.
And this minimizes downtimes due to
battery changing or battery charging.

coupling on request. A compressed air
supply unit is of course available for
operation with pneumatically braked
trailers. The range of accessories is
completed by various battery and tire
options.

Excellent visibility and clearly arranged
control elements
Higher operating safety
In modern production environments with their precisely synchronized processes, accidents
can lead to severe disturbances of operating procedures and even result in bodily injuries
if the worst comes to the worst. Therefore, maximum operating safety was one of our
priority development goals in the conceptual design of the VOLK Electric Tow Tractors EFZ
20 N – EFZ 30 N.
Double windscreen wipers Towing-fork safety catch
More safety thanks to good visibility
The driver's cab of the VOLK Electric
Tow Tractors EFZ 20 N – EFZ 30 N
features double-arm windshield wipers
as standard equipment. Compared
to conventional windshield wipers with
one arm, they feature a distinctly
enlarged wiping range and provide
The VOLK Electric Tow Tractors EFZ 20
N – EFZ 30 N have a high-performance
hydraulic double-circuit braking
system. This offers high safety reserves
particularly on ramps or when towing
heavy loads. With an optional crawling
switch, the speed can also be
reduced and precisely controlled on
ramps. If required, an automatically
activated parking brake can be fitted
to prevent the vehicle from rolling
