Stopping the machine suddenly can cause the load being transported to fall
Sudden braking can cause physical trauma caused by the safety belt that should be fastened.
Combined inching function
The machine is equipped with an inching function, which allows precision movement operations. To use
this function, the accelerator and brake pedals must be pressed simultaneously. By slightly releasing the
brake pedal, the machine will move slowly and progressively. The inching function can be used for a short
stroke of the brake pedal; if the pedal is pressed all the way, the machine stops.
Service brake
When the pedal (2) is pressed, the machine slows or stops; the action is transmitted to the servo-assisted
brake valve, which operates the brake discs inside the differential bridges. Being a servo-assisted brake,
braking is scarcely influenced by the amount of pressure exerted on the pedal. Even if pressed slightly, the
brake stops suddenly. The active parts of the parking brake system are integrated in the front differential
bridge; the service brake too acts on the front bridge only, and not on the rear one.
Both are oil bath discs, a system that guarantees constant efficiency over time in addition to the substantial
absence of maintenance. The operating principle is hydraulic. When the brake pedal is pressed, the brake
valve slide moves, allowing oil to flow toward the brake housing, compressing the brake discs together.
When the pedal is not operated, the brakes are free. With the machine off, the parking brake is
automatically engaged.
If the vehicle were to have its Diesel engine off, but the ignition key in position 1, a pressure accumulator in
the system guarantees a number of brakings until the lighting up of the relative low pressure light on the
side right dashboard. At this point, if the Diesel engine is not reactivated or if there is an anomaly/fault in
the hydraulic system, the brakes will no longer be able to guarantee the correct stoppage/stationary
condition of the vehicle. The same is true for the parking brake circuit, where a pressure accumulator
guarantees a minimum number of brake releases until the lighting up of the relative low pressure light on
the second side right dashboard. The system thus guarantees, in case of a breakdown or fault, movement
of the vehicle with the Diesel engine off and the ignition key in position 1.
