Confident machine operation starts with precise machine control enabled by the 815K's load sensing hydraulic steering system.
The 815K is specifically designed and made with purpose built structures to remain safe and durable for the long run. Advanced design, materials and robotic welding contribute to increased durability and overall machine strength.
The Cat C7.1 ACERT engine is designed for maximum fuel efficiency and increased power density. Two engine options are available to meet Tier 4 Final/Stage IV or Tier 3/Stage IIIA equivalent emission standards. This engine features innovative Cat electronics, fuel injection process, air-management systems and aftertreatment solution with Cat Selective Catalytic Reduction. While in operation, the aftertreatment will be seamless to the operator thanks to the passive regeneration system which is utilized.
Cat engines equipped with an SCR system inject DEF into the exhaust to reduce NOx emissions. DEF is a precisely mixed solution of 32.5% high purity chemical grade urea and 67.5% de-ionized water. DEF used in Cat SCR systems must meet the requirements outlined in the International Organization for Standardization (ISO) standard 22241-1.
Cat injection timing precisely controls the fuel injection process through a series of carefully timed microbursts, providing more control of combustion for the cleanest, most efficient fuel burn. On the 815K the high pressure common rail fuel systems boost performance and reduce soot for the C7.1 ACERT engine.
The modified chevron tamping wheel tip design provides greater ground pressure, more compaction, excellent traction and a smooth ride.
Compaction is achieved from the bottom of the lift to the top. The tapered tips walk out of the lift without “fluffing” the soil. The top of the lift is compacted and the surface is relatively smooth and sealed so hauling units are able to maintain a high speed when traveling over the fill. The 815K travel speed allows four forces of compaction: pressure, manipulation, impact and vibration. Since the 815K can also spread fill, the number of spreader tractors may be able to be reduced.
Equal compaction in forward or reverse is the result of the symmetrical tamping tip pattern. Tips are full perimeter and replaceable. The tip is welded to a base assembly, which then is welded directly to the drum.
Each wheel has two cleaner bars to keep the drums free of carryover dirt, regardless of rolling direction so efficiency is maximized. Cleaner bars are available with standard or abrasive tips depending upon the application.
The adjustable cleaner bar tips are heat-treated and direct hardened, cutting edge steel to increase wear life, which translates into lower operating costs.
COMPACT technologies combine advanced compaction measurement, in-cab guidance and reporting capabilities to help you consistently meet compaction targets fast, uniformly, and in fewer passes – saving on fuel and the cost of unnecessary rework.
The factory Cat Compaction Control system uses Machine Drive Power (MDP) technology to measure rolling resistance and correlates it with soil stiffness. MDP works in both cohesive or granular soils. Optional 3D mapping system maps compaction measurements to the precise location the operator is working, providing a real-time view of progress, and a record of compaction uniformity.
DETECT technologies help keep people and equipment safe by enhancing operator awareness of the work area around working equipment and by monitoring and reporting unsafe conditions, like avoidance zones.
The 815K is an efficient, productive machine that's designed to conserve our natural resources for generations ahead.
The 815K is built to be rebuilt with major structures and components capable of being remanufactured to reduce waste and replacement costs.
