Efficiency and Productivity
Delivering the efficiency and productivity you demand through integrated machine systems.
Advanced Productivity Electronic Control System (APECS)The new APECS is designed to improve transmission shifting performance, providing a higher level of comfort for the operator and increasing productivity.
Decelerator PedalThe left pedal acts as a brake, transmission neutralizer and an engine decelerator to override the engine speed selected by the throttle lock. This enables the operator to slow down when the throttle lock is engaged and to return to throttle lock without pressing a resume or set button again. This aids in maneuvering around trucks, tractors or any other obstacle.
Electro Hydraulic Controls

Engine and EmissionsThe 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.
Efficient Systems and ComponentsInnovative systems intelligently lower the average working engine speeds and reduce the overall system heat loads which result in significantly improved performance and fuel efficiency.
Advanced Systems with Innovative IntegrationThe deep system integration of the new engine and emissions system, power train, hydraulic system and cooling system result in lower fuel consumption on average compared to previous models.
Diesel Exhaust Fluid (DEF)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.
Next Generation Fuel SystemsCat 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.
Cat NOx Reduction SystemThe Cat NOx Reduction System (NRS) captures and cools a small quantity of exhaust gas, then routes it back into the combustion chamber where it drives down combustion temperatures and reduces NOx emissions.
Aftertreatment TechnologiesTo meet the additional 80% reduction in NOx emissions required by Tier 4 Final/Stage IV emission standards, one new system, the Selective Catalytic Reduction (SCR), has been added to the already proven Cat Tier 4 Interim/Stage IIIB aftertreatment solution.
Tamping Wheels and Tips
The heart of any compaction system.
Chevron Tamping Tip DesignThe modified chevron tamping wheel tip design provides greater ground pressure, more compaction, excellent traction and a smooth ride.
CompactionCompaction 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.
Symmetrical Tamping Tip PatternEqual 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.
Cleaner BarsEach 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.
Adjustable Cleaner Bar TipThe adjustable cleaner bar tips are heat-treated and direct hardened, cutting edge steel to increase wear life, which translates into lower operating costs.
