Mechanical overloading system, function description
1. Position sensor boom length 60 cm (B7224)
2. Position sensor damping boom in (B769-3)
3. Position sensor boom length 1.5m (B777)
4. Sensor steering axle load (B7221)
5. Position sensor boom angle 35
°
(B771)
6. Position sensor damping lowering (B769-1)
7. Position sensor damping boom out (B769-4)
This is the basic alternative for overloading system and it uses open-
ing sensors to sense the load.
The mechanical overloading system is activated when:
• The steering axle springs up (overloading forward).
In case of overloading forward the control system interrupts the
functions lift and lower as well as extension. Using the by-pass,
lower and extension can be activated to get out of the overload-
ing situation.
• The boom angle exceed 35
°
at the same time as boom exten-
sion is less than 1.5 m when the machine operates faster than
10 km/h (overloading steering axle).
In case of overloading on the steering axle the control system
activates a warning for overloading on the steering axle.
NOTE
In case of overloading on the steering axle it is up to the op-
erator to be careful when operating, no functions are inter-
rupted. To reduce the load and regain full operational
speed, the boom shall be lowered or extended.
