Pronar T680 SECTION 4

TIP
It is recommended to use wheel chocks in order to additionally secure the trailer during
unloading. When unloading high-volume materials, for example branches, the trailer's rear
wall may be opened downwards. The help of a second person is recommended during
unloading.
If a second trailer is hitched, it should be unloaded only when the load box of the first trailer
has been lowered and the hydraulic tipping system control lever is placed in position 2 --
tipping of the second trailer.
DANGER
Ensure that during unloading nobody is near tipped load box or load material pouring out.
Tipping the load box must be done on hard and level ground.
Tipping may only be performed when trailer is hitched to tractor.
Use only original pins with a handle. Use of non-original pins could damage the trailer.
Tipping pins must be correctly interlocked.
When opening the load box side wall locks take particular care because of the pressure
applied by the load to the walls.
When closing the rear chute gate or the walls take particular care to avoid crushing
fingers.
High-volume materials may be unloaded by tipping the load box to the rear only.
Rear load box wall is equipped with slide gate (1) – figure (4.5) and chute (2) (optional
equipment) which is used for unloading loose materials. Chute design allows very accurate
dosing of the material to packaging (sacks, boxes etc.). The opening gap can be controlled
using lever (3). In order to do that loosen the bolt interlocking slide gate (4), open the slide as
required and lock again using the bolt. When unloading through the chute do not open wall
locks or wall extension locks and tipping of the load box must be done very slowly and
without jerking. Raising the load box quickly will exert large pressure on the rear part of the
load box due to displacement of the carried material and could compromise trailer's stability.
