2 Product specication
The UNIVERSAL is a real allrounder. The welded construc-
tion of the frame and chassis of the UNIVERSAL are hot-dip
galvanised and thus optimally protected against corrosion.
Designed as a transfer loader, the UNIVERSAL is equipped
with a continuous base plate, which also makes it suitable
for other transport solutions apart from motor vehicles.
The UNIVERSAL is loaded with vehicles by means of drive-
on planks made of hot-dip galvanised grating. These are
stowed in a shaft under the loading area during the jour-
ney. The drive-on ramps can be easily moved across the
entire width so that you can load regardless of the track
width of the vehicles. Seven lashing rings per side, which
are integrated into the outer frame, provide load securing.
Furthermore, the UNIVERSAL has an additional hole embos-
sing in which the optionally available wheel stoppers can be
attached.The standard cable winch with cable is attached
to the front left or right of the trailer frame by means of a
3-position depth-adjustable tube bracket.A wide range of
accessories such as aluminium drop sides and a tarpaulin
with frame make the UNIVERSAL a multifunctional trailer.

3 Intended use
The UNIVERSAL vehicle transporter is designed to be
attached to a permissible towing vehicle. It may be loaded
within the permissible total weight.
The transport of dangerous goods, e.g. chemical substances,
is not permitted. It must be possible to distribute the weight
of the load evenly through the load. When loading the trai-
ler with a single load, this must allow an even weight distri-
bution. The centre of gravity of the load must be in front of
the axles. The permissible drawbar load must be observed.
The driver of the towing vehicle is responsible for securing
the load or equipment for securing the load. The driver must
observe the respective country-specic laws and standards
for load securing.
The trailer may only be operated in technically perfect
condition.
4 Use contrary to intended purpose
For all types of the UNIVERSAL vehicle transporter, the fol-
lowing shall be deemed to be improper use:
• Loaded with a too high payload.
• Transporting people with the trailer.
• Driving with an unsecured load.
• Exceeding the drawbar load and the trailer load
• Unauthorised structural modications to the trailer.
• Transport of hot materials (e.g. tar).

Correct charge distribution.
Vehicle (engine in front) properly charged.
All wheels of the trailer and the towing vehicle rest evenly
on the ground. Neither the trailer nor the towing vehicle
are tilted. Negative drawbar load is not permitted. The
permissible drawbar load of the towing vehicle must also
not be exceeded. The maximum drawbar load of the trailer
is indicated on the front of your trailer. The information can
also be taken from the vehicle documents. The drawbar load
must be within the permissible drawbar load.
Incorrect load distribution
Vehicle (engine in front) incorrectly charged.
The load‘s centre of gravity is too far back. The drawbar load
becomes negative. This increases the risk of skidding. The
axles are loaded unevenly. The rear axle of the tandem axle
of the trailer and the front axle of the towing vehicle are
loaded too much.
8.2 Cargo securing
Danger to life!
Driving with an unsecured load.
The load or parts of the load can be
thrown out and hit people. This can lead
to injuries or even death.
Secure the load for the journey.
The load must be adequately secured. You must check this
before and during the journey. To secure the load, the ve-
hicle transporter has lashing rails integrated in the loading
area, each with 7 lashing brackets. A maximum weight of
400 kg may be attached to each lashing bracket.
In addition, the trailer has a perforation in the outer frame
prole where wheel stops can be attached.
If vehicles are loaded, you must apply the handbrake (par-
king brake) of the vehicle.
Danger!
8.3 Loading and unloading the trailer
Risk of injury!
Entering the loading area with unsuita-
ble footwear.

9 How do I look after the trailer?
Property damage!
When cleaning with a high pressure
cleaner.
Too little distance, too high pressure or
too high temperature can damage the
trailer.
Keep the specied values.
Check whether the lubrication points are lubricated to
the point of grease leakage. If not, lubricate them. When
cleaning the trailer with a high pressure cleaner, note that it
may be operated with a max. pressure of 50 bar. Ensure that
the water temperature does not exceed a maximum value
of 80°C. Maintain a minimum distance of 70 cm. Please note
that the following parts must not be directly illuminated.
• All electrical parts
• The tyres
• The clutch
Do not use abrasive, acidic or alkaline cleaning agents, as
these may destroy the surface coating.
After driving on roads where salt has been spread or after
transporting fertilisers or other acidic or saline substances,
clean the trailer thoroughly with a high-pressure cleaner.
Acids, salts and certain chemicals may otherwise attack the
surface coating of the parts and destroy the eect of the
coating.
Special features of galvanized parts
Galvanised parts lose their shine over time. This eect is
desirable, as the rust protection eect of a galvanised coa-
ting only works in the oxidised state. To protect galvanised
surfaces, they can be treated with a commercially available
corrosion protection agent.
Aluminium drive-up ramps
To remove heavy soiling and maintain the aluminium shine,
use the Original Humbaur aluminium and tarpaulin cleaner
or equivalent cleaning agents.
Caution!
