WARNING
The interlock mechanism can be shifted by moving the hook frame only when the tipping
frame is in the resting position, the rear fender is withdrawn and the slides of the load box
interlock are in folded position.
The trailer is switched to "hook trailer" mode when the hook frame is shifted to position B.
In the whole range, the trailer will work as "tipper".
3.2.3 MAIN BRAKE
The hook trailer is equipped with one of three types of main brake:
•
double conduit pneumatic braking system with automatic braking force regulator,
figure (3.4) – standard equipment,
•
double conduit pneumatic braking system with manual braking force regulator,
figure (3.5) – optional equipment
•
hydraulic braking system, figure (3.6) – optional equipment
In standard configuration, the trailer is equipped with double conduit pneumatic system with
automatic braking force regulator.
The main pneumatic brake is activated from the tractor driver's cab by depressing the brake
pedal. Control valve (2) - figure (3.4) and (3.5) activates the trailer's brakes simultaneously
with the tractor's brakes. Furthermore, in case of an inadvertent disconnection of the conduit
between the trailer and the tractor, the control valve will automatically activate the trailer's
brakes. Valve used in the system is equipped with a circuit causing the brakes to be applied
when trailer is disconnected from the tractor. When compressed air line is connected to the
tractor, the device automatically applying the brakes now changes its position to allow normal
brake operation.
The main hydraulic brake (available as optional equipment) is activated from the tractor
driver's cab by depressing the brake pedal. Agricultural tractor equipped with suitable
hydraulic system output is required to operate the hydraulic braking system.
