3.3.3
Hand brake or parking brake
Hand brake which is supported by elastic gas suspension serves to safely park the machine. When the chassis
goes backwards the hand brake automatically adjusts.
- Handling the model with elastic suspension using gas: pull the hand brake until in neutral.
- To release the brake, the handle should be replaced in zero position passing through neutral.
- Handling the model with spring cylinder; pull the handbrake up to the last ratchet.
3.3.4 Retention device
When the traction vehicle brakes, or goes downhill, the traction bar is introduced, the brake responds
according to the size of the force of the trailer shaft.
Also when moving in reverse, the brake responds at first. Since the brake drum moves backwards, the effect
of the brake is almost eliminated. When adjusting the retention device, ensure that it is parallel to the main trailer
shaft. If not, the brakes will not function.
.
3.3.5 Coupling head ball or pin
The chassis is prepared depending on the option chosen for transport by car (ball) or by lorry (pin).
National regulations of the countries where the machine is to be transported should be observed.
3.3.6 Middle part of tow bar
The middle part is the connection between the retention device and the tow shaft.
3.3.7 Tow shaft
The tow shaft has a regulator. This means that the height for the transport coupling can be easily and
conveniently regulated.
Before every journey check the safety of the towing bar regulator.
•
Bear in mind that when regulating the height of the retention device it is parallel to the towing bar.
Check that the toothed heads are correctly fitted together and that the attachment handle is properly
tightened, and that the safety ring is correctly inserted. If not, there is no guarantee that the brakes will work.
•
If there is a ring as traction device, check that the traction vehicle’s blocking system is properly
fitted. If it has a head, check that this is correctly coupled on the ball of the traction vehicle.
•
Change the height only in flat areas.
•
Secure the machine with the brake block to stop it rolling, then release the handbrake.
If a specific height is maintained for long periods, the toothed head coupling may rust and deteriorate,
therefore regular cleaning of the toothed coupling is recommended.
Periodic maintenance work should be carried out on these elements checking the state of the toothed heads
and the threads, rivets and attachment handles. If a part appears to be excessively worn, it should be replaced.
WARNING!
The safety ring is absolutely essential. It must be replaced in the event of loss or wear. Check the
state of the brake cable of the inertia coupling, and the safety cable.
3.3.8 Suspension axle
The suspension axle does not need maintenance and cannot be lubricated as the grease may attack the rubber
elements.
