HYDRAULIC SYSTEM General The task of the hydraulic system is to operate the ma- chine’s functions by means of hydraulic pressure and ﬂ ow. The system consists of hydraulic pump, tank, cooler, hydraulic motor, hydraulic cylinders, ﬁ lters and valves of various kinds. Hoses or pipes connect the components with each other.
ELECTRIC SYSTEM General The electric system consists of a high-voltage circuit and a low-voltage circuit. High-voltage circuit High-voltage is used as a power source for both the electric motor and the low-voltage circuit. An automat- ic phase rotation change-over switch ensures that the electric motor has the correct rotation direction.
The machine’s electric system 1. Aerial 2. Electric cabinet 3. Pressure switch 4. Temperature sensor 5. Warning light 6. Power cable 7. Electric motor 8. Control module 9. Radio module ELECTRIC SYSTEM 10. Work lighting 11. Pressure sensor 12. External tool 13.
General The remote control, the electronics unit and the pilot control valves are the main components in the control system. The signals from the remote control are trans- mitted to the machine via bluetooth or via a cable. The electronic unit in the machine transmits the signals via the pilot control valves to the hydraulic system by converting electric current into hydraulic pressure.
