are equipped with hydraulic locks (3), which are designed to block the tailgate in the raised
position. The use of hydraulic locks increases the safety of trailer use.
Hydraulic locks (3) are designed to lock the tailgate in a fixed, unchanged position in the
event of the system unsealing.
The tailgate is controlled from the tractor cabin through the lever of the tractor's external
hydraulic distributor.

3.5 FLOOR CONVEYOR MECHANISM HYDRAULIC SYSTEM

The Pronar T400 trailer is equipped with a floor conveyor mechanism hydraulic system -
figure (3.5), designed for automatic unloading of volumetric materials by moving the scraper
bars backwards with the help of chains. This solution ensures unloading of transported
materials in silos or on piles without the need to tip the load box.
The conveyors hydraulic system is supplied with oil from the external hydraulic system of the
agricultural tractor. Hydraulic oil from the quick couplers (5) goes to the stream divider (4),
which is designed to split the oil stream for two hydraulic motors (1). The motors drive the
reducers (2), which are coupled to the shafts of the conveyor mechanism. Both conveyors
