Komat'su PC 5500-6 Monster Excavator

CONTROLS: "A-D"-(Drive Train Steering). "*ALT A-D"-(Horizontal Ring Steering). "*ALT W-S"-(Bucket Contractions). "Mouse Pitch Up&Down"-(Vertical Boom Pitch)

NOTE: "THIS VEHICLE IS IN BETA OPERATION, PLEASE BE AWARE OF TWEAKS AND PATCHES."

OVERVIEW: The 1.1 million pound PC5500-6 Features two 1260 hp diesel motors. If a mine would prefer to use electrical power, the PC5500-6 can be equipped with two electric motors instead of diesel. Like smaller Komatsu mining excavators, backhoe or shovel fronts can be fitted to the PC5500-6.

throughout the platform Hydraulic System The power train consists of two main drives. Each of the two gearboxes drives three identical pumps which draw hydraulic oil from an unpressurised hydraulic tank. Open circuit hydraulics provide maximum cooling and filtering efficiency. Rated flow (total output) 4200 ltr/min 1110 gpm Relief valve setting 310 bar 4,495 psi Swing flow rate 700 ltr/min 185 gpm High pressure in line filters one per pump located at the valve blocks

200 microns Full flow return line filters (10 double elements) at head of hydraulic tank

10 micron Case drain/by-pass return line filters

3 micron The four-circuit system features a load-limiting governor with oil delivery summation to the working circuits and incorporates pressure cut-off control. Hydropilot prioritises hydraulic flow giving smooth hydraulic response, simple hydraulic system layout, and a reduced number of components. The hydraulic system includes large swing-out vertical airto- oil hydraulic coolers with temperature-regulated hydraulically driven fans. Automatic Centralized Lubrication Three hydraulically powered Lincoln single line automatic lubrication systems are provided as standard, complete with time and volume variable controls. The two central lubrication circuits and open gear grease circuit are supplied by identical pump assemblies from refillable containers which have a capacity of 3 x 300 litres (3 x 80 gal). Replenishment of the containers is through the Wiggins connections on the service arm.

The cab has automatic climate control and is pressurised. The operator’s seat is air suspended, electrically heated and has a lap seat belt and offers multiple adjustments. The trainer seat is also equipped with a seat belt. Low-effort joystick controls are electrohydraulic with foot controls for front shovel clam, crawler and swing brake. Full instrumentation, KOMTRAX Plus and an AM/FM radio with MP3 ready CD player with AUX in is fitted. The windshield wash wiper has two speeds and intermittent operation. Amenities include a refrigerator and storage cabinets. Powered and heated mirrors are adjusted from inside the cab. External metal sun blinds on the cab side window and interna roller blinds on all windows are standard. The left hand window is an emergency exit. All windows are tinted parsol green. The front window is a 19mm thick impact resistant window. A walkway is mounted in front of cabin. KOMTRAX Plus Health Monitoring System KOMTRAX Plus is designed for Komatsu mining equipment to provide real time information about the operating status of the machine via a coloured display. The integrated digital storage provides a full event history and trend data, which can be downloaded by laptop. Optionally available are W-LAN or Orbcomm satellite transmission (check for availability in your territory).
