Productivity and Reliability in a Durable Package

The AP-1055D Asphalt Paver with ACERT®Technology offers fuel efficiency, high
performance, speed and job versatility to maximize productivity.

C7 Engine with ACERT®Technology

✔

ACERT®Technology works at the
point of combustion to optimize engine
performance. ACERT®Technology
incorporates an electronic controller to
precisely deliver multiple injections of
fuel. These multiple injections are
combined with a refined air
management system in order to
generate fewer emissions and optimize
fuel combustion while meeting U.S.
EPA Tier 3 and E.U. Stage IIIa engine
emission regulations. The C7 engine is
a turbocharged, 6-cylinder diesel
engine that provides 167 kW (224 hp)
of gross power (SAE J1995) at
2200 rpm with a maximum torque of
872 N-m (643 ft/lb).

High Capacity Cooling System

✔

The high capacity cooling system
performs efficiently in high ambient
temperatures. The variable speed fan
draws air across the engine
compartment and exhausts it away
from the operator and engine
compartment in order to provide a
cooler working environment for the
tractor and screed operators.

Dual Operator Stations

✔

The AP-1055D incorporates dual
operator stations that can be rotated to
four different positions. The stations
have fully equipped consoles with
meter per minute (feet per minute)
gauges, adjustable suspension seats,
armrests and retractable seat belts. The
operator stations can be positioned
beyond the machine frame. Extending
beyond the frame provides the operator
with good visibility when paving wider
than 3.05 m (10 ft). This is important
when matching a joint or when
working along existing structures
where precise paving control is
required.

Undercarriage Selection

✔

The AP-1055D can be purchased with
either the Mobil-trac™ undercarriage
or the steel track undercarriage. The
Mobil-trac
traction and flotation benefits of a
crawler undercarriage with the
mobility, speed, and ride characteristics
of a wheel paver. The steel track
undercarriage incorporates track rollers
and a rear bogey system in order to
provide a smooth ride.

Generator (Optional)

The generator is integrated within the
machine frame and is located below
the operator platform, between the dual
operator stations.
generator provides power to the
electrically heated screed and the
auxiliary power panel. A single control
switch located on the tractor’s center
control console activates the generator.

Auxiliary Power Panel (Optional)

The optional auxiliary power panel is
available for simultaneous use with the
electric screed. The auxiliary power
panel supplies power to four, 120-volt
and two, 240-volt receptacles. The
120-volt receptacles are protected with
ground fault circuit interruption
(GFCI).

Cat®C7 Engine with ACERT®Technology

ACERT®Technology incorporates a series of innovations working at the point of
combustion to optimize engine performance while meeting U. S. EPA Tier 3 and
E. U. Stage IIIa engine emission regulations.

Aftercooling (ATAAC)

The turbocharged air-to-air aftercooling
system provides high horsepower with
increased response time while keeping
exhaust temperatures low for long
hours of continuous operation.
Air-to-air aftercooling keeps air intake
temperatures down, maximizing fuel
efficiency and minimizing emissions.

Cat®C7 Engine with ACERT®Technology

The C7 engine provides a full-rated
gross power (SAE J1995) of 167 kW
(224 hp) at 2200 rpm with a torque of
872 N-m (643 ft/lb). The combination
of large displacement and high torque
allow the AP-1055D to perform under
the toughest conditions.

HEUI Fuel Injection

The HEUI™ fuel system is unique and
combines the technical advancement of
an electronic control system with the
simplicity of HEUI fuel injection. The
HEUI fuel system excels in its ability to
control injection pressure over the entire
engine operating speed range. These
features allow the C7 engine to have
complete control over injection timing,
duration and pressure.

Multiple Injection Fuel Delivery

Multiple injection fuel delivery involves
a high degree of precision. Precisely
shaping the combustion cycle lowers
combustion chamber temperatures,
which generates fewer emissions,
optimizes fuel combustion and
translates into more work output for
your fuel cost.

High Cylinder Pressures

High cylinder pressures combined with
tightly controlled tolerances promote
extremely efficient fuel burn, less
blow-by and lower emissions.

C7 Cylinder Block

The C7 engine’s cylinder block offers
increased tensile strength. It features
improved sealing with gaskets to ensure
fewer leaks. This new design supports
the engine’s higher compression ratios
and increases its power density. The
incorporation of straight-thread “O” ring
connection points reduce the loss of
engine oil and fluids.

Sound Reduction Features

The C7 engine sound reduction features
include composite valve covers with a
fully isolated base, a steel oil pan and a
cast iron front cover. The HEUI™ fuel
systems rate-shaping technology also
provides control of sound and vibration
levels.

Service, Maintenance and Repair

Easier service, maintenance and repair
is accomplished by monitoring key
functions and logging critical indicators.
Advanced electronic diagnostic
capabilities are possible using CAT

echnician.

ADEM™ A4 Electr

The ADEM A4 electronic control
module manages fuel delivery, valve
timing and airflow to get the most
performance per liter (gallon) of fuel
used. The control module provides
flexible fuel mapping, allowing the
engine to respond quickly to varying
application needs. The control module
also monitors engine and machine
conditions while keeping the engine at
peak efficiency.

High Ambient Temperature Cooling System

The standard, high-capacity cooling system provides efficient operation in high ambient
temperatures. The new system design also provides quiet operation that benefits the
operator and the surrounding environment.

flow

Air

The airflow design draws ambient air
across the engine compartment and
through the radiator. This new design
allows the exhaust air to exit the right
side of the machine in order to provide
a cooler engine compartment and
operator platform.

High Capacity Cooling Package

The high capacity cooling system
allows the fan to run slower, reducing
power demand while extending
component life.

Variable Speed Fan

The variable speed fan is electronically
controlled and hydraulically driven to
provide on-demand cooling. This
on-demand operation reduces engine
power demand and provides quiet
operation.

Dual Operator Stations

The dual operator stations provide complete control and good visibility from either side of
the operating platform.

Dual Operator Stations

The dual operator stations incorporate
fully equipped consoles with meter per
minute (feet per minute) gauges,
adjustable suspension seats, armrests
and retractable seat belts.

Operator Visibility

The dual operator stations can be
positioned in one of four dif
locations to provide optimum visibility.
The stations can extend beyond the
machine frame for good visibility when
joint matching or while paving other
applications where precise control is
required.

Center Control Console

The center control console includes
analog gauges, switches and a digital
display for machine functions. The
center console also houses a majority
of the electrical components for fast,
easy service.
