HYDRALIC SYSTEM
The hydraulic unit is driven by 100 HP cage motor. One side of the motor shaft is connected to a variable displacement pump with electromagnetic directional flow control to four different capacity outlets for the belt conveyor drive. Maximum capacity:               120 to 160kg/cm²

The other side of the motor shaft is connected to a coupling gear with three driven shafts which operate the following pumps:

• Two pumps for the crawler's movement (capacity 1251-135 kg/cm².

• One pump for the hydraulic jacks (capacity 1501-150 kg/cm².

• One pump for the servo controls (capacity 10L-20kg/cm².

The pumps are provided with pilot operated overload valves. The hydraulic systems indudes a 1000L oil tank with pressure and suction oil filters and a motorised fan cooling unit.
