CUMMINS
QSL Engine
Heavy-duty strength
Everyone who’s ever worked on construction
equipment knows, there is no substitute for
power and durabilty. The QSL handles the
toughest loads and the roughest work conditions.
At the same time, it delivers better fuel economy,
has better cold starting capability and is up to
50% quieter in operation.
Plus, the heavy-duty design of the QSL engine
block and components such as articulated
pistons, enhanced camshaft and roller cam
followers, viscous damper and high capacity lube
system add reliability and durability you can
count on every day, year after year.
Both fuel-efficiency and response are
significantly enhanced with Cummins high
pressure common rail fuel system. The system
delivers high pressure injection independent of
engine speed for optimum performance and
flexibility at every rpm.
Track Rail Guide & Adjusters
Durable track rail guides keep track links in place. Track adjustment is made easy with standard grease
cylinder track adjusters and shock absorbing springs. (Full Track Guide : Option)
Strong and Stable Lower Frame
Reinforced box-section frame is all welded, low-stress, high-strength steel.
It guarantees safety and resistance against external impact when driving on rough ground and working
on wet sites through high tensile strength steel panels, with highly durable upper and lower rollers and
track guards. Long undercarriage incorporates heavy duty excavator style components.
X-leg type center frame is integrally welded for maximum strength and durability.
Powerful and Preciser Swing Control
Improved shock absorbing characteristics make
stopping a precise and smooth action
Reinforced Bucket and Bucket
Linkage
Sealed and adjustable bucket linkage provides less
wear of pins and bushes
as well as silent operation.The design includes
bucket link durability and anti wear characteristics.
Additional reinforcement plates on cutting edge
section. Reinforced bucket is made with thicker
steel and additional lateral plate.
Self Diagnosis System
The CPU controller diagnoses problems in the
CAPO system caused by electric and hydraulic
malfunctions and displays them on the LCD
monitor of the cluster through error codes. This
controller has the capacity to identify 48 distinct
types of errors. As the information from this
device, such as engine rpm, main pump delivery
pressure, battery voltage, hyd. temperature, and
the state of all types of electric switches, provides
the operator with a much more exact state of
machine operating condition.
This makes the machine easier to troubleshoot
when anything does go wrong.
One Touch Decel System
When the one touch decel switch is pressed, CPU
controller controls the accel actuator to reduce
engine speed to 800 rpm. And then the one touch
decel switch is pressed again, the engine speed
recovers.
Pump Flow Control System
In neutral position: Pump flow is reduced to a
minimum to eliminate power loss.
In operation: Maximum pump flow is delivered to
the actuator to increase the speed. With movement
of the control lever, pump flow is automatically
adjusted and the actuator speed can be
proportionally controlled.
Boom & Arm Holding System
The Holding valves in the main control valve
prevents the boom & arm from dropping over an
extended period in neutral position.
Arm Flow Regeneration System
Arm flow regeneration valve provides smooth
arm-in operation without cavitation.
Hydraulic Damper in Travel Pedal
Improved travel controllability & feeling by shock
reducing when starting and stopping.
Auto Deceleration System
When remote-control
valves are in neutral
position more than 4
seconds, CPU con-
troller instructs the
accel actuator to
reduce engine speed
to 1100rpm. This decreases fuel consumption and
reduces cab noise levels.
Max. Flow Cut-off System
For precise control and finishing work, the Max.
Flow Cut-off System reduces pump flow, thus
allowing smooth operation.
ADVANCED CAPO SYSTEM
NEW MODE CONTROL SYSTEM
Power boost control System
When the power boost system is
activated, digging power increases
about 10%.
It is especially useful when extra
power is temporarily needed, for
instance, when digging hard earth
and rock, or if the bucket teeth are
stopped by a stubborn tree root.
Automatic Engine Overheat
Prevention
If the engine coolant temperature
gets too high, the CPU controller
lowers the engine speed and cools
the engine.
Automatic Warming-up System
After the engine is started, if the
engine coolant temperature is low,
the CPU controller increases the
engine speed and automatically
increases the pump flow rate to
warm up the engine more
effectively.
Anti Restart System
The new system protects the starter
from re-starting during engine
operation, even if the operator
accidentally turns the start key
again.
Advanced Hydraulic System
Increased Higher Performance
The advanced CAPO(Computer
Aided Power Optimization)
system maintains engine and
mutual pump power at optimum
levels. Mode selections are
designed for various work loads
and maintaining high
performance while reducing fuel
consumption.
Features such as auto
deceleration and power boost are
included in the system. The
system monitors engine speed,
coolant temperature, and
hydraulic oil temperature.
Contained within the system are
self diagnostic capabilities which
are displayed by error codes on
the cluster.
