Aggregate handler for greater payloads
Caterpillar introduces the 990K
Aggregate Handler, designed to handle
greater payloads in aggregates yard
applications. With as much as a 25%
payload increase, as compared to the
standard 990K, the new Aggregate
Handler enables customers to load trucks
and railcars faster and to move more
material in load-and-carry and stockpile
management tasks.
The Cat 990K Aggregate Handler has
a payload of 22 tons (20 tonnes) and a
full turn static tipping load of 96 426lb
(43 738kg). Additional counterweight
maintains machine stability, and robust
990K structures ensure durability in the
Aggregate Handler configuration. The
loader makes best use of general purpose
and coal buckets for increased volume.
The 990K Aggregate Handler is
available in standard-lift configuration
with 13.5ft (4 108mm) dump clearance
and in high-lift configuration with 15ft
(4 569mm) dump clearance. Increased
capacity and high dump clearance enable
customers to load railcars and large
trucks with a better pass match for faster
material handling at lower cost per ton.
The 990K Aggregate Handler
complements the smaller 986K and
988K aggregate handlers in the Cat
large wheel loader line. The Aggregate
Handler, however, is not designed for
use in quarry face or other shot rock
applications.
Building on the 990K
The new 990K Aggregate Handler is
built on the proven features of the 990K
Wheel Loader. The 990K powertrain
provides powerful operation with superior
fuel efficiency. The Cat C27 engine
powers the loader and delivers net
power of 699hp (521kW). Lower engine
speed helps drive economical fuel use.
Additional fuel savings accrue with the
ECO Mode (on-demand throttle), engine-
idle shutdown system, and engine-idle
kickdown/auto-resume system.
The Cat exclusive, field-proven
impeller clutch torque converter uses
a lock-up clutch, providing direct drive
to boost fuel economy, trim cycle
times, and reduce heat — especially in
load-and-carry applications. The system
allows operators to balance rimpull and
hydraulic power for optimum loading
efficiency. Positive Flow Control
implement hydraulics use a variable
displacement, electronically controlled
pump to precisely apportion oil flow
based on operator control inputs.
A number of drivetrain options are
available. The integrated axle cooling
and ride control options are particularly
beneficial in load-and-carry work.
The operator station features the
Cat Vital Information Management
System, VIMS™ 3G, which provides
customisable operator profiles, a
cycle timer, and an integral Payload
Control System, which provides on-
the-go payload weighing. The graphical
information display is easy to use
and keeps key information in front of
the operator. The Cat Comfort III seat
provides integrated seat-mounted
controls for smooth and comfortable
operation. Transmission controls, integral
with the STIC™ steering lever, allow
convenient travel control.
The 990K is equipped with the Cat
Vision rear-view camera system and
in-cab display to show the operator the
area behind the loader. The Cat Detect
object detection system, available as
an option, builds on the camera system
with radars and in-cab software that
provide notification to the operator when
an object is detected within the radar
coverage area. The systems are designed
to enhance operator awareness,
especially in congested loading areas.
The Cat 990K Aggregate Handler has a payload of
22 tons (20 tonnes) and a full turn static tipping
load of 96 426lb (43 738kg).
