The 3469 kW 4,650 HP retarding system provides state of-the-art braking capacity for navigating today’s mining applications which contain steep continuous descents and sharp switchbacks.
This power capacity, coupled with the ultra-quiet, high volume, low speed fan makes it possible for the operator to maintain control with confidence while hauling downhill. Electric retard reduces the need for service brake applications.
The Komatsu drive system, utilizing Siemens AC control, offers independent control of the rear wheelmotors. This provides outstanding traction during wet and slippery conditions, thus improving tire wear and operator confidence.
The liquid cooled Insulated Gate Bipolar Transistor (IGBT) inverter system technology provides the highest available reliability.
During slippery conditions caused by inclement weather and/or application severity, the 860E-1K traction control technology utilizes information from all four wheels to detect and correct wheel spin and/or slide events. Traction Control operates automatically and independently of the service brakes, providing a more efficient means of controlling the machine in inclement conditions.
Trolley (optional)
The factory installed 860E-1KT trolley system allows for faster ascent up grades, providing higher production and lower fuel consumption compared to conventional diesel systems.
Hill Start
With the new Komatsu Drive System comes a new innovation in electric truck technology. The Hill Start feature allows the operator to start the machine on a grade without roll back.
Steering
By using double acting hydraulic steering cylinders with a six-point articulation linkage, the 860E-1K power steering system provides positive steering control with minimal operator effort. The turning circle has a diameter of 31 m 102 ft. The accumulator-assist steering system surpasses requirements set forth by ISO 5010.
Hydropneumatic Suspensions
Hydrair® II suspension cylinders located at each wheel provide a smooth and comfortable ride for the operator and dampen shock loads to the chassis during loading and operation.
Ergonomically Designed Cab
The Komatsu 860E-1K cab design provides the operator with an environment where they can be comfortable and confident during operation. The rubber mounted isolated cab includes tinted safety glass, power windows, heating and air conditioning, acoustical insulation, double sealed doors, and filtered, pressurized air.
Castings Used in High Stress Areas
To increase frame reliability, steel castings have been incorporated at key frame pivot points and key load bearing critical portions of the frame. This includes the rear body pivot and horsecollar sections.
By using advanced computer-aided design, finite element analysis, and full-scale dynamic and static testing, the frame design has been structurally enhanced to carry 254 t 280 short tons and provide high reliability.
Dynamic Retarding
For daily operation, the 860E-1K is equipped with an electric retarding package which can supply up to 3469 kW 4,650 hp of resistance. When requested, the wheel motors switch from motors to electrical generators. The resistive force created from this process is used to slow the truck to the desired speed. The power generated is then run over an 18 element grid which converts the electricity into heat. The heat is then dissipated into the atmosphere by the quietest grid blower Komatsu has ever used.
Fully Hydraulic Controlled Multiple-Disc Wet Brakes
The 860E-1K comes standard with four-wheel, hydraulically actuated, oil cooled service brakes. In the event that the truck’s hydraulic system pressure drops below an acceptable level, accumulator tanks will automatically apply all wheel brakes to bring the truck to a complete stop.
Max. service apply pressure: 16547 kPa 2,400 psi
Total friction area per brake: 75439 cm² 11,693 in²
Payload Policy
Recognizing that variation occurs naturally in material density, fill factors, and loading equipment, Komatsu America Corp. deems it necessary to establish a consistent loading policy for the 860E-1K. This loading policy is intended to identify the guidelines for the loading of Komatsu Mining Trucks, and is valid for approved applications and haul profiles only (see chart below).
10-10-20 Load Policy Criteria
10% of all loads may be between 110% and 120% of the rated payload of the truck
90% of all loads must be below 110% of the rated payload of the truck
The average monthly payload must not exceed the rated payload of the truck
No single payload may exceed 120% of the rated payload of the truck
* Net flywheel power is the rated power at the engine flywheel minus the average accessory losses. Accessories include fan and charging alternator.
