Cat Soil Compactors are designed with durability built in, ensuring maximum availability
through multiple life cycles. With optimized performance and simplified serviceability,
our machines allow you to operate more efficiently and safely.
Representing a long-standing commitment to quality and performance, this rugged,
powerful machine is designed and built for heavy-duty compaction and dozing operations.
Focused on helping our customers succeed, we have continued to build upon each
new series. The 815K continues our legacy of reliability, performance, safety, operator
comfort, serviceability, and efficiency.
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 Pedal
The 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
Operators increase productivity with our responsive
implements feature.
• Operate comfortably through electronically controlled
hydraulic cylinder stops
• Handle easy-to-use soft detent controls
Steering System
Confident machine operation starts with precise machine
control enabled by the 815K’s load sensing hydraulic
steering system.
• Increase efficiency with our variable displacement
piston pumps
• Achieve precise positioning for easy loading in tight
areas with 42 degrees each way of steering articulation
• Enhance operator comfort with integrated steering
and transmission control functions
• Smoother, faster cycles help reduce operator fatigue
through the use of Steering and Transmission Integrated
Control System (STIC™)
1) Decelerator
2) Brake
3) Accelerator
Purpose-built from the ground up
for the toughest conditions.
Robust Structures
Your bottom line is improved by highly durable structures that achieve multiple life cycles and withstand the toughest loading conditions.
• Full box-section rear frame resists torsional shock and twisting forces
• Heavy-duty steering cylinder mounts efficiently transmit steering loads into the frame
• Axle mounting has been optimized for increased structural integrity
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.
Engine and Power Train
Operate more efficiently with improved power
and control.
Engine and Emissions
Diesel Exhaust Fluid (DEF)
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.
Efficient Systems
and Components
Innovative systems intelligently lower
the average working engine speeds and
reduce the overall system heat loads
which result in significantly improved
performance and fuel efficiency.
Next Generation Fuel Systems
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.
Cat NOx Reduction System
Cat Planetary Powershift
Building your success begins with a
best-in-class transmission.
• Consistent, smooth shifting and efficiency
through integrated electronic controls that
utilize Advanced Productivity Electronic
Control System (APECS).
• Long life and reliability through heat treat
gear and metallurgy.
• Three forward and three reverse speeds
to match your application.
Advanced Systems with
Innovative Integration
The 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.
The 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 Technologies
To 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 Design
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.
Symmetrical Tamping Tip Pattern
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.
Cleaner Bars
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.
Adjustable Cleaner Bar Tip
The adjustable cleaner bar tips are heat-treated and direct hardened,
cutting edge steel to increase wear life, which translates into lower
operating costs.
Your operators can work more efficiently and stay
comfortable with our customer-inspired cab features.
Your operator’s productivity is enhanced with our clean, comfortable cab
• Experience reduced vibrations from isolation cab mounts and seat air

Cat Compaction Control
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.
LINK Technologies
LINK technologies wirelessly connect you to your equipment, giving you valuable
insight into how your machine or fleet is performing so you can make timely,
fact-based decisions that can boost job site efficiency and productivity.
Product Link™/VisionLink®

information like machine location, hours, fuel usage, idle time and event codes
via the online VisionLink user interface can help you effectively manage your
fleet and lower operating costs.
DETECT Technologies
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.
Rear Vision Camera
A rear vision camera greatly enhances visibility behind the machine to help the
operator work more productively. Work with greater confidence and at peak
potential while keeping people and assets safe.
Making your safety our priority.
Machine Access
We are constantly improving our products in an
effort to provide a safe work environment for the
