Chinese launch new large wheel loader

Chinese company LiuGong has launched its largest wheel loader to date at Bauma China.

The manufacturer used the event to unveil its CLG8128H wheel loader, which is designed for large projects.

The machine features a 4.04 metre dumping height, a bucket with 7 cubic meters of capacity and a movable blade, and a DANA-C9672 torque converter.

According to International Mining it has a 12 tonne rated load, and 360kN breakout force.

The Chinese firm added that it takes only 7.4 seconds to raise the bucket for full loading.

Caterpillar launches its largest ever wheel loader

Cat has developed its largest ever wheel loader – the 994K.

The new machine has a greater payload capacity than its predecessor, the 994H, cutting down the number of passes required to load large haul trucks.

The standard 994K can carry 40.8 tonnes per pass, with the high lift version able to move 38.1 tonnes per pass, approximately 18 and 20 per cent more, respectively, than the previous models.

“The 994K loads mining
trucks in the 250, 200 and 150 short ton classes in one less pass than the
previous model. The high lift configuration is a six-pass match with the
popular Cat 793 mining truck, and the high lift as well as the standard
configuration loads the Cat 789 in five passes,” Caterpillar said.

The machine has also been upgraded in terms of engine power, hydraulics, breakout force, and rimpull, as well as lateral stability.

Cat’s 994K has also been designed with Australian operations in mind, with a new high ambient package allowing the loader to operate in temperatures as high as 50 degrees Celsius.

An optional fuel tank now holds enough fuel for 24 hours straight operation without refuelling.

In regards to its bucket “new high performance
buckets in a wide range of capacities are optimized for the 994K linkage
kinematics,” Cat said. 

“The new bucket design has an extended floor, larger radius and
angled side bars for fast loading, high fill factors and good material
retention.”

It has a bucket capacity ranging from 19.1 to 24.5 cubic metres for the standard and high lift.

“A number of efficiency
improvements, such as the electronically controlled and hydraulically driven
cooling system fan, also help keep operating costs down.”

It is powered by a Cat 3516E engine, which produces 1297kW of power, and works through a Cat planetary powershift transmission designed specifically for mining applications.

“An
integral Impeller Clutch Torque Converter and Rimpull Control System allow the
operator to precisely adjust power at the wheels to specific loading conditions
by modulating rimpull from 100 to 25 percent, reducing potential for tire
slippage without diminishing hydraulic capacity,” Cat added.

Safety has also been a focus of the new machine, with it featuring a reduced stair angle for easy access and egress, increased visibility for operators, optimised LED lighting, and improved cameras for greater site awareness, and reduced sound in the cab to help fight operator fatigue. 

For service operators the wheel loader has been designed so engine oil change intervals are 500 hours minimum, with all routine service points are conveniently located on the left side of the loader, while hydraulically driven auto lube handles linkage greasing.

The 994K wheel loader will be commercially available in the first quarter of 2016.

​Cat launches new wheel loader

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
