ROTVs (Remote Operated Tug Vehicles) provide many Advantages.
One major Benefit is the Ability to generate additional Parking & Hangar Space.
Moving an aircraft the conventional
way with a tug and towbar, or a
traditional towbarless tug, requires
a lot of space. In order to steer the
aircraft considerable movement is
required. Turning the nose gear can
only be achieved by moving the air-
craft forward or back. Extreme cau-
tion is required to prevent nose gear
oversteering and to avoid damage
to the sensitive nose wheel landing
gear. The aircraft must be moved
several yards before the nose gear
can be turned and to steer in a new
direction. This conventional method
requires significant space during
aircraft maneuvering.

Difference! Thanks to the proprietary and pa-
tented 360° 4-axle steering technology with pendulum floating
axle and soft capture wheel coupling, TowFLEXX
can turn any
aircraft literally on the spot. Thats revolutionary, highly innova-
tive, unique and unmatched compared to any other product in
the market.
Unique and best-in-class”. The 360° technology compensates rotational
resistance and equalizes transverse forces. No gimbal mounted platform
and no hydraulic compensators are required.
Most other tugs available in the market are much more restrict-
ed and do not provide the same level of steering flexibility. The
risk of nose gear oversteering is a real peril when towing air-
craft. TowFLEXX
is the only ROTV that is equipped with intelli-
gent steering control.

Difference! Operating in tight areas,
and generating additional hangar space is the hall-
mark of TowFLEXX
. Utilizing conventional tow trac-
tors with towbar, or towbarless tugs (most of them are
designed in the 60’s but still widely used on many air-
ports), is cumbersome and time consuming.
Turning the aircraft and maneuvering without over-
steering the nose wheel and without moving the plane
a considerable distance forward or backward is im-
possible with those old technologies. Conventional
tugs also require significant room for an exit path.
That makes it virtually impossible to position any air-
craft with its nose close to a wall or in a corner.
Hangar operators are not utilizing available hangar
space and valuable real estate. Older and outdated
technology prohibits to reach full hangar capacity and
to increase revenues for FBOs and hangar owners.

Advantage! Towing and maneuvering Aircraft with TowFLEXX
is easy, much safer, and definitely the most advanced Method of handling Fixed
Wing and Helicopter Aircraft.
Turning the ROTV, turning the nose gear, and moving
the aircraft are three different actions. The patented
360° steering technology feature makes
the difference. Overall this results in much less space
requirements and elevates the hangar and apron utili-

No Need to maintain a large Selection of
onerous and expensive Aircraft Towbars.
No Need to disconnect Linkages and to
apply various greasy Adapters.
No Risk of Oversteering, and expensive
Nose Gear Damage / Repairs are com-
pletely eliminated.
No more Hangar Rush and Aircraft Damage

Just imagine what you dont need anymore and how much easier it will be with the TowFLEXX
one Person can do it all. The Operator is mobile, not tied to a
Tug Driver Seat, and he is Wing Walker while controlling and steering all
simultaneously. Multitasking made very easy.
No Need for Wing Walkers and additional Staff. Personnel Cost can be significantly reduced. TowFLEXX
increases your Efficiency.

TowFLEXX® ROTVs are designed
for commercial applications and
24/7, 365 days around the clock
usage. Real drive tires are a needed
prerequisite for winter operations.
The tires can also be equipped with
snow chains.
Caster wheels used as drive
wheels are well known for
their limitations under cer-
tain conditions. They are
mostly used indoors (e.g.
production floors, ware-
houses, etc.), and not al-
ways suitable outdoors.
ROTVs can be used in Winter Conditions
Example with Model 5.0 (the same applies to Model 600 RC)
TowFLEXX® ROTVs are equipped with real Optimum Tread Depth and All-Terrain Drive Tires, not with caster
wheels as used by others. Caster wheels dont perform well on wet, icy, or snowy surfaces.
All TugMAXXE ROTVs come with optimum sized Wheels.
you dont need to be concerned about Functionality and

Better Control, and built for Flexibility
Better Power & Force Control
Hydraulic Systems are sized correctly
Electromechanical Systems are fully integrated
Designed with Low-Maintenance in Mind
Robust Chain Drive
No direct shaft drive with motor and gearbox directly
connected to the drive wheels, also commonly known as
"Final Drive"
Chains are reliable, last a long Time and are very easy
to maintain
Direct Shaft Drives require more complex Maintenance
Chain Drive Systems smoothly absorb Shock Loads
from Acceleration, Braking or Road / Tarmac Surface
Chain Drives absorb Vibrations and assure that those
vibratory Effects are not transmitted to the Nose Gear
and Aircraft
A Chain Drive provides better Torque Characteristics
Direct Shaft Drive Failures can be catastrophic and
with little Warning resulting in high Repair Cost
provides a more robust and more reliable drive technology. There
is a reason why 95% of all industrial floor-borne vehicles, as well as other
mobility vehicle products are equipped with chain drives.
