1.5 TRANSPORT
The trailer is ready for sale completely assembled and does not require packing. Packing is
only required for the machine's technical documentation and any extra equipment. The trailer
is delivered to the user either transported on a vehicle or, after being attached to a tractor,
independently (trailer towed with a tractor).
1.5.1 TRANSPORT ON VEHICLE
Loading and unloading of trailer from vehicle shall be conducted using loading ramp with the
aid of an agricultural tractor. During work, adhere to the general principles of occupational
health and safety (OHS) applicable to reloading work. Persons operating reloading
equipment must have the qualifications required to operate these machines. The trailer must
be properly connected with the tractor according to the requirements in this Operators
Manual. The trailer braking system must be started and checked before driving off or onto
ramp.
ATTENTION
Whe bei g road tra sported o a motor vehicle the trailer must be mou ted o the
vehicle's platform i accorda ce with the tra sport safety requireme ts a d the
regulatio s.
Driver of the vehicle should be particularly careful duri g travel. This is due to the
vehicle's ce tre of gravity shifti g upwards whe loaded with the machi e.
Use o ly certified a d tech ically reliable securi g measures. Carefully read the
i formatio co tai ed i the Operator's Ma uals for the give securi g measures.
The trailer should be attached firmly to the platform of the vehicle using straps or chains fitted
with a tightening mechanism. Securing elements should be attached to the transport catches
designed for this purpose (1) – figure (1.3), or permanent structural elements of the trailer
(longitudinal members, crossbars etc.) Transport catches (hooks and eyes) are welded to
upper longitudinal frame (2), with one pair on each side of the trailer. Use certified and
technically reliable securing measures. Worn straps, cracked securing catches, bent or
corroded hooks as well as elements damaged in a different way may be unsuitable for use.
Carefully read the information contained in the Operator's Manual for the given securing
measure. Chocks, wooden blocks or other objects without sharp edges should be placed
under the wheels of the trailer to prevent it from rolling. Trailer wheel blocks must be nailed to
the low platform planks of the vehicle or secured in another manner preventing their
