1.2 INTENDED USE
The trailer is designed for transport of harvested crops and agricultural products as well as
loose, bulk and long load materials at the farm and on public roads. It is acceptable to

steel, destr ction of paint coat, dissolving plastic elements and destr ction of
r bber elements etc.),
•transport incorrectly sec red load, which d ring travel may ca se
contamination of the road and nat ral environment,
•transport incorrectly sec red load, which d ring travel may change position
in load box or fall o t of the load box,
•transport loads, whose centre of gravity may destabilise the trailer,
•transport loads, which have neven load distrib tion and/or overload axles
and s spension elements.
The trailer is designed according to current safety requirements and engineering standards.
The brake system and the light and indicator system meet the requirements of road traffic
regulations. The maximum speed of the trailer on public roads in Poland is 30 km/h (pursuant
