​Komatsu launches new rental business

Komatsu Australia has launched a new equipment rental
business on Australia’s eastern seaboard, and New Zealand.

The business is providing more than 200 Komatsu construction
and utility machines with a team of 11 staff.

This is not just another finance solution with ownership
responsibilities and balloon payments at the end of a lease period,” Komatsu
Rental’s national rental manager Geoff Pisani said.

“And as the only national OEM-backed rental operator,
Komatsu Rental customers get all the advantages of Komatsu machine owners
including access to our KOMTRAX and KOWA machine management reporting systems,
and complete integration with our technical and service operations.

“That means Komatsu Rental customers are able to enjoy the
same level of support that is available to a Komatsu machine owner.”

According to Pisani the rental business is an area of major growth
potential for the business.

“We see it growing very strongly over the next few years,
with Australia and New Zealand on track to follow major overseas markets, including
the US, Japan and Britain,” he said.

“These markets have seen sales to the construction equipment
rental sector grow rapidly over the past 15-20 years.

“Much of the demand
for Komatsu Rental equipment is coming from Komatsu customers, who are keen to
rent the latest low-hour equipment from us, and to receive the full service and
technical support that we offer all our customers,” he said.

“Previously, if a Komatsu customer needed a machine to rent
for a short-term project, they were forced to rent from another supplier.

He went on to say that a number of companies are looking to
the hire and rental market as they have limited access to capital.

“Many contractors and plant hire companies today have
limited access to capital, so the rental option is very attractive to them.

“There is also the changing demands of the major project
environment, where the major contractors no longer own all of their equipment,
instead engaging plant hirers and subcontractors – who in turn can see the
advantages of renting quality low-hour equipment during the term of their
project,” he said.

“We see many opportunities supporting plant hire companies –
many of whom are also our customers – who need to supplement their fleets to
meet ever-changing project demands.

“These days, major customers are preserving their capital
for fixed plant and infrastructure and are increasingly looking to rental as a
flexible solution to supplement their existing mobile fleet, especially during
periods of increased production.”

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 hydraulic mining shovel

Caterpillar has released its new 22 tonne 6020B hydraulic shovel for mining.

The shovel features a 22 tonne payload, and weighs in at 224 tonnes itself.

The 6020B features a new cab and operator station with increased visibility provided by a large floor window and expansive windshield and side windows, Caterpillar said.

“Unrestricted lines of sight to the crawler trucks and pit floor aid the operator when repositioning the shovel and when loading trucks,” it said.

The cab also includes two additional seats for a trainer and observer, making this three seat cab design the first in this size class of shovels.

“All the mining company operators working with our three test machines—in three different countries—adapted to the 6020B very quickly, regardless of their previous experience on other equipment,” Steve Maloney, a Caterpillar operator trainer, said. 

“The three-seat cab design allowed me to train two operators at the same time, making operator training more efficient; and the elevated trainer’s seat provides an unobstructed view of the digging area, which is crucial when training operators on new equipment.”

The hydraulic mining shovel features a modular construction, with a walk through power module that enables easy access to components and increased serviceability.

This modular design also aids shipping and field assembly of the machine.

A single engine configuration also simplifies maintenance.

The 6020B is powered by a 778kW Cat C32 ACERT engine.

Pump-flow allocation technology drives hydraulic pump utilisation to reduce operating energy losses and increase fuel savings, while pumps also move hydraulic oil through a cooling circuit to maintain optimum oil temperature in the harsh Australian mining environment.

It also features an automatic lubricant system to reduce service times and ensure durability.

Cat’s 6020B is configured as a backhoe and handles a standard bucket size of 12 cubic meters.

It has both a coal bucket and a MultiPlus rock bucket for use in dense rock and aggressive digging conditions.

The buckets feature hammerless teeth, which have been designed specifically for the 6020B, and have simple 180 degree turns to lock and unlock each tooth for faster and safer removal.

Caterpillar has designed the hydraulic shovel to use four of the Cat MineStar System’s capability sets – Detect, with more cameras and sensing technology; Terrain, for loading guidance; Fleet, for tracking and production reporting; and Health, for machine condition reporting.

Pre-production versions of the 6020B have been field tested at the Rosebel gold mine in Suriname.

Komatsu launch new dual bushing undercarriage concept

Komatsu has released Dual Bushing Track for large dozer undercarriages to double track life.

The new track has been designed for high abrasion, low impact applications, and eliminate the need for pin and bush turns and associated new sprockets.

According to John Mortimer, Komatsu
Australia’s BDM for undercarriages, the first
application of dual bushing track in Australia – on a D275A-5 dozer – achieved
more than 3000 hours of operation with no issues, compared to average track life of around 1000 hours, including a pin and bush turn at 500 hours, on conventional undercarriages.

“In this application, a large sand
mining site, we actually effectively tripled the life of the undercarriage –
and it would have gone longer if the dozer had not been redeployed elsewhere,” Mortimer
said.

“By the time the dozer finished on
the site, the track was approximately half worn, so we believe it had the
potential to run to 4000 or even 5000 hours. Seal life would have ultimately
determined the longevity of the track before the bushes went.

“In that 3000 hours, there were
absolutely no issues,” he said.

“There were no dry or hot pins, and
the system avoided three pin-and-bush turns, which would have required a week’s
downtime to take off and put back on.”

However Mortimer added that it can not be used in high impact applications such as ripping or hard rock work.

“Having said that, it is ideal for
sand, bauxite and other high-abrasion applications where you have large
stockpiles to be moved around, with no ripping,” he said.

​Caterpillar launches more efficient wheel dozer

Cat has launched its new 824K wheel dozer with increased
durability.

The manufacturer states that the new wheel dozer builds on
its predecessors, with refinements in its power train, operator cab, structure,
and safety features.

The machine has a net power rating of 302kW and operating
weight of 34 tonnes, and is available with six blade configurations ranging in
capacity from 5 to 16.2 cubic metres.

Its Cat C15 ACERT engine comes with an electronically controlled
fuel delivery system, engine idle shutdown systems to converse fuel by limiting
idle time, and a delayed shutdown feature.

The engine provides a max travel speed of 35 kilometres per
hour.

Drive train efficiency has been enhanced with a lock up
clutch in the Cat torque convertor, which reduces train power losses and system
overheating.

An electronically controlled 4F/4R Cat power shift
transmission increases drive train efficiency, and can be set by the operator
to automatically upshift or downshift based on machine speed.

In addition single clutch speed shifting control s allows
the wheeled dozer to carry momentum through range shifts for increased
productivity.

“Both operating efficiency and operator convenience get a
boost with the left foot pedal, which serves as
an engine decelerator, transmission neutraliser and brake, depending on the
degree of application,” Cat said.

“As a decelerator, the left pedal allows the operator to
temporarily reduce engine speed by overriding the throttle lock setting when manoeuvring
around obstacles.”

A new larger fuel tank also provides a minimum 12 hours
operation, depending on the application, while an optional tyre pressure
monitoring system provides real time information to the operator in the cab,
ensuring proper inflation levels.

The Steering and Transmission Integrated Control (STIC)
system allows for single-lever steering and transmission control, with simple
side to side movements providing up to 43 degrees of steering articulation in
both direction whilst buttons on the lever provide fingertip control of
directional and range shifting.

Safety and comfort have been two major factors in the
redesign of the operator’s cabin, with a lighted, shallow angle stairway for
entering and exiting the cab, and the STIC armrest able to fold away for added
room during ingress and egress.

The Cat Comfort Series air-suspension seat features extra
thick cushions and moves both the attached electro-hydraulic STIC control pod
and electro-hydraulic implement control pod when adjusted.

The cab, isolation-mounted to the frame, is pressurised
with filtered air and the selected temperature is maintained automatically.

The control panel uses large, backlit switches with LED
indicators, and a simple two-position rocker switch controls the parking brake.

An optional rearview camera with in-cab monitor increases
operator awareness.

Maintainability has also been key, with maintenance points
grouped and accessible from ground level or non-skid walkways protected with
handrails.

Swing-out doors on both sides of the engine compartment
provide easy access to daily service checks, and ecology drains simplify
service and help prevent spills. In addition, a ground level power service centre has
electrical disconnect, emergency engine shutdown and stairway light switches.

The Cat VIMS 3F program is integrated into its design to
keep operators informed about machine operating conditions.

The Cat Product Link system provides event and diagnostic
codes as well as data such as operating
hours, fuel level, and idle time.

Regarding the dozer itself, it features a full box-section rear frame designed to resist
twisting forces and shock loads encountered in heavy dozing.

Steering cylinder mounts are designed to effectively
dissipate steering loads into the frame, and axle mounts are heavy-duty
components that contribute to the overall structural integrity.

Komatsu develops remote monitoring iPhone app

Komatsu has developed an iPhone app for its KOMTRAX remote machine monitoring system.

According to Komatsu the free app “gives instant access to vital information on every KOMTRAX equipped Komatsu machine in the user’s fleet”.

“Our new
KOMTRAX app gives Komatsu customers the ability to monitor critical machine operating
parameters, along with usage, performance and location, as well as overall
fleet management,” Todd Connolly, Komatsu Australia’s head of fleet management and ICT, said .

“By providing
customers with valuable information regarding their Komatsu machines, it helps
get a quick overview of what machines in their fleet have been up to – all via
their iPhone.”

The app provides a number of different features for users which include the standard identification of each machine’s location (including driving directions based on the phone’s location); the machine’s hours of use; idle time identification; fuel usage monitoring; whether any machine cautions have been triggered; and an ability to identify any machines that have not been used through a ‘no usage’ feature’.

“All these
features can be customised so users can view set time periods, from one day up
to a month,” Connolly said .

“In addition,
a fleet can be filtered by model, customer management number or serial number.

“Komatsu’s
KOMTRAX remote monitoring system was one of the first OEM-specific systems on
the market, and has proven itself an invaluable tool in fleet and machine
management,” he said.

Caterpillar launches new dozer

Cat has released the new D10T2 tracked dozer.

According to the company this new dozer builds on the existing D10T, and features refinements to its power train, automated controls, and its structure.

Cat states that it uses advanced load sensing hydraulics combined with Cat engine control “to maximise the amount of material moved for every drop of fuel burned”.

This system automatically and continuously adjusts implement hydraulic power and delivers the right levels of flow and pressure, allowing for more power available for the tracks.

Enhanced AutoShift (EAS) is also included as a new standard feature on the D10T2.

“EAS improves fuel efficiency and productivity by automatically selecting the optimal gear and engine speed combination based on power train load and desired ground speed,” Cat said

“This feature functions similarly to an automatic transmission. EAS functionality combined with the increased power in reverse enhances productivity when backing up slopes.”

New electronic systems are also now available.

Autocarry, which provides automatic blade control during the carry segment of the dozing cycle by measuring ground speed and track slip in included, with a new feature – Adaptive Load Select – enhancing Autocarry by automatically adjusting blade load based on operating conditions, such as underfoot conditions and track wear.

Similarly, the new Automatic Ripper Control monitors speed with GNSS and automatically adjusts engine speed and ripper depth to minimise track slip.

The dozers are designed with improved filtration to protect the fuel system, hydraulic system, and power train oil system to cut downtimes.

The manufacturer has refined its structure by redesigning its track roller frames, as well as providing improved access and egress features to enhance safety.

It has developed two variations of the D10T2, one with a Cat C27 engine with ACERT, and the other with a US EPA Tier IV Final certified engine.

Both variations have a net power of 447kW in forward gears and 538kW in reverse.

Cat added that the new model “has about 20 per cent more power in reverse compared to its predecessor model. This results in faster cycle times and greater productivity in certain applications”.

It has an operating weight of 70 tonnes, and a semi-universal blade capacity 18 cubic metres and a universal blade capacity of 22 cubic metres.

Cat launch new wheel dozer

Caterpillar has launched its new 834K wheel dozer.

It’s an updated version of the Cat 834 stable, that has been operating on sites for nearly half a century.

The 834K comes with a completely new cab design, drive train refinement, new monitoring and diagnostic features, more safety features, and additional structural enhancements.

Powered by a 370 kW Cat C18 engine, which comes in a Tier 4 Final version, Tier 3 equivalent, and Tier 2 version, the engine uses an actuated, electronic unit-injection system for precise control of fuel delivery and greater performance.

It has a top speed of 35km/h.

It has a number of fuel saving enhancements built-in, such as engine-idle-shutdown and engine-idle kick-down systems, as well as delayed engine shutdown systems to protect the machine from hot shutdowns.

An on-demand hydraulically driven cooling fan also reduces horsepower draw for greater efficiency.

A Cat 4F/3R planetary power-shift transmission is used, and features an Advanced Productivity Electronic Control Shifting system for greater vehicle momentum through shift points.

A forced flow oil lubricates and cools the transmission high-torque clutches for longer component life.

For increased control, Cat have included a clutch torque convertors that allows the operator to adjust rimpull from 100% to 25% to match hydraulic effort and rimpull accordingly.

This aids in reducing tyre wear as well.

The 834K’s cab has been completely redesigned, with automatic temperature control, touch-screen displays, electro/hydraulic parking brakes, and comfortable seats with integrated controls.

Noise levels have also been reduces to 71dB.

The wheel dozer has retained its massive full-box-section rare frame which resists torsional shock, while heavy duty steering cylinder mounts are included to transfer and dissipate steering loadings into the frame.

Available blade types include straight, universal, semi-universal and coal, ranging in capacity from 7.9 to 22.2 metres cubed.

The blade mounting push beams have a ‘through-width’ design, as opposed to simply being attached to the side of the frame, which dissipates the stress of blade corner loading into the frame.

It also has a redesigned rear axle trunnion, which is now wider and bolted directly to the frame rails.

This eliminates the previously used intermediate casting and allows loads to be more effectively dispersed.

Its lower articulation point has also been strengthened, with an increase in front frame thickness and an increase in pin diameter.

Safety has also been a focus in the latest iteration of the 834 wheel dozer.

The new model features standard rearview cameras, repositioned access ladders, full permitter railings, and ground level panels that house stairway light switches, engine shut-down switches, and lockouts.

Service points are accessibly from ground level or from its large, skid resistant platforms.

Swing-out doors on both sides of the engine give ready access to daily maintenance items, and ecology fluid drains facilitate service and protect the environment.
