Caterpillar has released its latest wheel loader, the 990K.
It has been designed to replace the 990H
According to Cat this new wheel loader “offers more power
and increased payload for greater productivity and fuel efficiency”.
There are a number of new features on the machine, including
a redesigned cab, better operator and maintenance technician safety features,
and technology designed for better overall performance.
The machine has been designed to operate with Cat’s 773,
775, and 777 trucks.
Its payload is rated to 16 tonnes, a jump from the 15 tonne
payload of the H Series model.
“The increased payload makes the new loader a perfect 4-pass
match with the Cat 775 truck for efficient, high-production loading,”
Caterpillar said.
The new ‘Performance Series’ buckets also allow for fast
filling and full bucket loads on every pass, and are available in sizes ranging
from 8.6 to 10 cubic metres.
It has an operating weight of 80 tonnes and a static tipping
load, full turn of 44 tonnes.
Caterpillar’s 990K is powered by a Cat C27 ACERT engine,
which delivers an 11 per cent increase in overall power compared to the 990H.
It has a net power of 521kW for increased production,
without any major change in fuel consumption.
A lower engine speed also aids more economical fuel use.
“Additional fuel savings accrue with the 990K ECO Mode (on-demand
throttle), engine-idle shutdown system, and engine-idle kickdown/auto-resume
system,” it said.
Drive-wise, it features a field proven impeller clutch
torque convertor that uses a lock-up clutch that provides direct drive to boost
fuel economy, trim cycle times, and reduce heat, in particular for
load-and-carry applications.
“The system allows operators to balance rimpull and
hydraulic power for optimum loading efficiency.”
Its
positive flow control implement hydraulics use variable displacement, electronically
controlled pumps to apportion oil and movement based on precise operator
control.
A
redesigned cab now provides greater access and egress as well as increased
noise suppression, cutting levels down to 69.9 dB.
Its
seat also has integrated, seat-mounted controls for smoother operation.
The machine has a Cat Vital Information Management System
(VIMS) 3G “which provides customizable 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”.
It also equipped with a rearview camera system and in-cab
display to show the operator the area behind the loader.
For increased maintenance safety a remote panel houses a
stairway light switch, engine shutdown switch, and lockouts for the
transmission and engine starter
A second panel provides convenient access to the battery disconnect
switch and a jump-start receptacle. Routine maintenance points are easily
accessed, including hydraulic pressure taps and oil sampling ports.
An optional ground level service centre, whichdisplays fluid level
status, houses drain-and-fill ports and provides a data port for diagnostic
work, reduces service time
