The improved accuracy of payloadmeasurement and reliability of the system are designed tooptimize payloads, maximize productivity, and reduce thelife cycle costs of the truck. PLM III tracks and records thefollowing key production parameters: Payload Empty Carry-Back Operator Haul Cycle, Loading, Dumping Time of Day Distance Traveled (Loaded and Empty) Cycle Time Information Maximum Speeds (Loaded and Empty) TMPH for Front and Rear Tires Average Speed (Loaded and Empty)SteeringBy using double acting hydraulic steering cylinders with asix-point articulation linkage, the 860E-1K power steeringsystem provides positive steering control with minimaloperator effort. The turning circle has a diameter of 31 m102 ft.

The systemutilizes a common tank, and therefore, common fluid forsteering, braking, and hoisting. In-line filtration elementsprovide optimum hydraulic system protection fromcontamination. These elements can be replaced fromground level, to enhance the serviceability of the Used in High Stress AreasTo increase frame reliability, steel castings have beenincorporated at key frame pivot points and key load bearingcritical portions of the frame.

8 This includes the rear bodypivot and horsecollar Change Pump ModuleTo keep pump change-out time to a minimum, Komatsuhas developed a sub-frame module which contains boththe steering / brake and hoist pumps. This module can beremoved and replaced as a single unit, helping limitpotential downtime and allowing easy access to thehydraulic pumping Retarding For daily operation, the 860E-1K is equipped with anelectric retarding package which can supply up to 3469 kW4,650 hpof resistance. When requested, the wheel motorsswitch from motors to electrical generators. The resistiveforce created from this process is used to slow the truck tothe desired speed. The power generated is then run overan 18 element grid which converts the electricity into heat is then dissipated into the atmosphere by thequietest grid blower Komatsu has ever used. 860E-1 KELECTRICDRIVETRUCKI ntegrated Park Brake To further reduce the maintenance on the 860E-1K, Komatsu has included an integrated, spring applied, parkbrake.
