Komatsu Introduces HM400-3 Articulated Truck
December 20, 2011
Rolling Meadows,
Ill. —Komatsu
America
introduced the HM400-3 articulated truck. The HM400-3 is powered by a Komatsu
SAA6D140E-6 engine with 469 horsepower (350 kW), and is EPA Tier 4 Interim and
EU Stage 3B emissions certified. Komatsu, building on its proven Tier 3 engine
platform, designed a more environmentally friendly engine that increases power
while decreasing fuel consumption.
With the introduction of the Komatsu
CARE Program, every Komatsu Tier 4 Interim construction machine comes standard
with complimentary factory scheduled maintenance for 2,000 hours or the first
three years (whichever occurs first), and includes two complimentary Komatsu
Diesel Particulate Filter (KDPF) exchanges within the first five years. The
Komatsu CARE program covers all new Komatsu Tier 4 Interim equipment, whether
rented, leased or purchased.
The HM400-3 features a maximum gross vehicle weight (GVW) of 162,569-lbs.
(73,740 kg), hauling up to a 44.1 ton payload at its maximum ground speed of
34.7 mph. Improved operating performance, lower fuel consumption, improved
operator comfort and enhanced serviceability are features of the HM400-3 that
provide increased productivity and lower operating costs.*
The HM400-3 is equipped with the latest KOMTRAX technology, which
sends machine operating information to a secure website utilizing wireless
technology. Data such as daily fuel
consumption, machine utilization, operating hours, location, cautions and
maintenance alerts are relayed to the web application for analysis. The KOMTRAX fleet monitoring system increases
machine availability, reduces the risk of machine theft, allows for remote
diagnosis by the distributor and provides a wealth of other information to
drive business efficiency and productivity.
Special features of the new HM400-3
include:
- EPA
Tier 4 Interim and EU Stage 3B Emissions Certified Engine
Built upon proven Tier 3 technology, the SAA6D140E-6 engine
provides increased horsepower while lowering fuel consumption. The Komatsu Tier 4 Interim engine uses an
advanced electronic control system to manage airflow rate, fuel injection,
combustion parameters, and after-treatment functions to enhance performance,
reduce emissions and provide advanced diagnostic capability.
As a leader in hydraulic technology, Komatsu has also developed a
hydraulically actuated Variable Geometry Turbocharger (KVGT) and Exhaust Gas
Recirculation (EGR) valve, resulting in better precision and air management as
well as longer component life. The KDPF
filter and regeneration system are integrated so as to not interfere with daily
operation but keep the operator aware of its status.
- Improved
Operation
The HM400-3 features the new Komatsu Traction Control System
(K-TCS). The K-TCS system automatically
provides optimum traction when operating in soft ground conditions. As ground conditions worsen, speed sensors
located on four wheels detect tire slippage, and automatic application of the
inter-axle differential lock occurs. If
tire slippage continues to be detected, four independent brakes can be applied
to slipping wheels to regain traction.
The HM400-3 is enhanced with Komatsu Advanced Transmission with
Optimum Modulation Control System (K-ATOMiCS). K-ATOMiCS offers a six-speed,
fully automatic transmission that uses an advanced electronic system to
eliminate shift shock and torque cutoff to aid operator in operating the engine
in the most efficient range. The electronic system automatically selects the
gear based on vehicle speed, engine speed and the shift position selected,
resulting in powerful acceleration, smooth down shifting and synchronized
engine speed when climbing slopes. K-ATOMiCS works to minimize operator fatigue
and load spillage from the body, thus increasing productivity.
A large automatic retarder allows the operator to select the
optimum operating speed on downhill travel and fully loaded hauls, thus
eliminating effects by inertial acceleration.
- Increased
Payloads
Through body design optimization the HM400-3 features increased
body capacity and payload. The low 10-ft,
5-in (3164 mm) loading height easily matches with 40 ton to 60 ton hydraulic
excavators or 5.5 yd3 to 7.5 yd3 wheel loaders. In
addition, the two single-staged body lift cylinders provide a 70-degree dump
angle.
- Enhanced
Operator Environment
The new cab design provides a more comfortable and quieter work
environment. The ROPS/FOPS Level 2
certified cab features a newly designed rounded front dash panel with
easy-to-reach switches. The dashboard
has been redesigned and the high back, heated air ride seat with three point
seat belt has been relocated to improve visibility. An auxiliary input has also been added to
connect an MP3 player or other device along with two 12-volt ports that have
been incorporated into the cab.
A new high resolution 7-in LCD monitor features enhanced
capabilities and displays information in 25 languages for global support. Using the monitor, the operator can easily
modify settings for items such as the Auto Idle Shutdown or the Auto-Reversing
Fan; check operational records, such as driving history or fuel consumption; and
monitor the KDPF or check for when the next maintenance interval is
required.
The monitor also offers the operator the option of using the ECO
guidance function, which provides operational tips to reduce fuel
consumption. A rear view monitor system
with a separate 7-in LCD monitor is standard with every machine and is mounted
on the right hand side of the console for operator convenience.
- Maintenance
and Serviceability
To
reduce costly downtime, the HM400-3 provides easy service access. The new model features a newly designed
engine hood for easy access, and two standard hydraulically driven
auto-reversing fans to help keep the radiator and charge air cooler clean.
The
truck is equipped with the exclusive Komatsu Equipment Management Monitoring
System (EMMS) that has enhanced diagnostic features that
give the operator and technicians greater monitoring and troubleshooting
capabilities. EMMS continually monitors
all critical systems, preventative maintenance schedule, and provides
troubleshooting assistance to minimize diagnosis and repair time.
