OPERATING INSTRUCTIONS 6030, 6030FS Operation Undercarriage The undercarriage of the hydraulic excavator serves as a stable base and for travelling. The crawler tracks are driven hydraulically with oil motors and travel gearboxes. Undercarriage and superstructure are connected by means of a swing ring.
Superstructure The superstructure accommodates the drive and part of the hydraulic and electrical equipment.
Drive The drive unit comprises diesel engines, pump transfer gearboxes, hydraulic pumps, hydraulic cylinders and hydraulic motors.
Hydraulic system All working and travelling movements are performed hydraulically. The movements are controlled by servovalves. The working commands are initiated by hand and transmitted to the valves via control circuits. The oil supply from the superstructure to the undercarriage is ensured by the rotor. The hydraulic system is overload-protected by pressure-relief valves. The hydraulic pumps are supplied with oil from a hydraulic reservoir.

Control and Monitoring Platform (CAMP) The electronic CAMP system ensures the control and monitoring of all electrical and hydraulical functions of the excavator. Four interconnected electronic units ensure optimal use of the installed engine power. Microprocessors are used to adapt the power output of the hydraulic pumps optimally to actual operating conditions. The machine is thus prevented from demanding more hydraulic power than the diesel engines can provide. The desired working movements are detected by microcontrollers which permanently sense the position of hand levers and pedals. As soon as movement is detected, the corresponding signals are transmitted to the electronic units. These units activate the drive control in order to provide the hydraulic energy needed for working. Only then do they activate the electrohydraulic valves which control the execution of the working movements.
