Komatsu Forest’s new formative harvester range
Unique stability and operator comfort
TODAY KOMATSU Forest Pty Ltd has one of the most comprehensive new Harvester range to meet all the demands of the Australian market. This has been achieved over the last two years with the introduction of a new range of Komatsu wheel harvesters which includes the largest wheel harvester, the 951.
During the same period the new, updated Komatsu XT Series 3 track machines were released and more recently Komatsu Forest Pty Ltd has released the Timberpro TL765C & TN765 tailswing purpose-built track feller-buncher, harvester; this is one of the largest purpose-built track machines on the market.
In addition, Komatsu Forest has invested heavily in recent years to develop the Komatsu PC270-8 into a forest ready carrier for contracts that are price sensitive -- in other words it’s a forest budget carrier!
Komatsu wheel harvesters
Komatsu Forest launched four brand new harvesters in 2015, the Komatsu 901, 911, 931, and 951 with the 931 and 951 being the most suitable for Australian conditions.
These new models include everything from completely new designs, a new cab with a damping option, and eco-friendly Stage IV engine through a keyless system, a new hydraulic system with dual hydraulic circuits the like of which the market has never seen. The result is high production capacity and low fuel consumption per processed timber volume. The focus for KF was on the operator and every effort was made to maximize production from every possible angle. The new harvesters are built on the well-proven concept of a centrallyplaced crane and cab and a swing axle that together with the cab’s tilt cylinders offers unique stability and operator comfort.
Major new features:
• The industry’s first remotecontrolled keyless system (300 metres)
• Automatically logs into MaxiXplorer with the operator profile.
• A new 3-pump hydraulic system,
• Provides a unique interaction between the crane, the head functions, and the transmission.
• The result is that the operator can use several crane and head
• functions together with maximum hydraulic power.
• Agco Stage IVTIER4 Final engines
• TIER IIB option for Australia.
• All models have new parallel cranes
• High lifting power which are fast, effective, and easy to operate.
• Choice of cranes with different reaches.
• Heads suitable for 931 & 951 are S132, C144, S172 & C202E.
The new harvester line up has a modern and functional design facilitating service and maintenance. Daily inspections can be carried out without having to open a hood.
Komatsu XT Series 3
The Komatsu XT series is a well proven product in the Australian market with a population of over 430 units of all models. The introduction of the Series 3 models two years ago came with many improvements. Models include the XT430-3 , XT430L-3, XT445L-3 and the larger new XT460L-3.ranging in operating weight from 27,805 kg to 32,659 kg.
Komatsu’s continued focus on improving operator productivity was considered very important, therefore the XT-3 has a totally new cab design.
Cab changes include:
• Sloped roofline that increases headroom and reduces debris build up.
• Larger skylight, front & side windows with 90% greater viewing depth.
• Brilliant white LED lights (11) deliver 2-3 times more illumination.
• More spacious, quieter and pressurized interior.
• Ergonomic seat and easy-to-reach controls.
• Easier access to new storage areas including a lunch box and thermos. The XT-3 Series features the new IQAN-MD4 “1st in the Forest” programmable digital control system. All former analog gauges and warning lights are now prominently displayed on the highly visible and durable 18 cm LED colour touchscreen. The system accommodates individual preference settings for multiple operators, records machine data and provides advanced diagnostic reports.
The XT-3 series machines include the latest Komatsu undercarriage and hydraulic improvements for greater reliability and durability, including:
• 1-2 additional bottom rollers improve track chain support and load distribution
• Upgraded chain guide (rock guard) material extends service life
• Track chain alignment has been optimized by utilizing:
• A continuous straight-line chain guide profile
• Lengthened chain guide profiles at the idlers and sprockets
• Removable track roller guards for easier access on XT445L & XT460L
• Hydraulic System:
• Upgraded Implement Pump bearings provide longer service life
• Lift capacity at full reach has increased by 37% on the XT460L-3 model
The XT 3 Series machines are capable of handling many of the larger heads for tougher felling and harvesting operations in both hardwood and softwood. There are many variants fitted with KF, Waratah, Logmax, Quadco and Woodsman Forest attachments operating in Australia and New Zealand.
The Timberpro TL765C is a totally new machine design but it has a very long heritage starting back with the Timbco brand. Komatsu Forest Pty Ltd has had a long and
strong relationship with Timbco and Timberpro dating back to 1992. Komatsu Forest believes this new tailswing levelling machine will have a strong demand in Australia and New Zealand. Timberpro were very fast to meet this challenge by completing the whole development project within two years with construction of the first prototype in Dec 2015.
The Timberpro TL765C was released to the Australian market at “Austimber 2016” which drew much interest with quick orders resulting in five being delivered and several orders in hand. The first TL765C in Australia was delivered straight from the Austimber show to Clearwater Logging and was fitted with a Woodsman 750. The initial success here in Australia and in the USA / Canada markets has made availability a major issue for future sales in Australia due to this strong demand.
The Timberpro TL765C has provided an excellent base for a great variety of attachments with current examples such as; Komatsu 398/ C283, Woodsman 750, Waratah 624 &625 Harvesting Heads, Woodsman FH1350, KF 800 Directional Felling Head, Quadco 26B Disc Saw and Quadco 7320 Accumulating Shear.
Some of the many features of the new TL 765C are:
• Cummins QSL 9.0L Engine
• Auto-Reversing Fan
• Energy Recovering Hydrostatic Dual Motor Swing System
• Energy Recovering Smart Valve
• Dedicated Dual Hydrostatic Drive System
• New Rexroth Drive Motors GFT 8190 (Tractive Effort :484 kN)
• IQAN MD4 10” Touch Screen Control System
• Excellent Serviceability
Komatsu PC270-8/C202E & PC300LC-8/PC400LC-8
Komatsu Forest Pty Ltd has been developing the Excavator range over many years. Whilst this design will always be evolving, the current product design is very stable and reliable. The earlier years of the design work mainly involved the PC220LC-8 but it was quickly realised that the higher horsepower of the, PC270-8 was the best option going forward for a budget harvester carrier, especially when the capital investment was not that much more than a PC220LC-8, it was quickly seen to be justified by the increased production.
The features of this size carrier along with the larger models were carefully considered, reliability was the number focus followed closely by performance and the overall capital expense.
The key components for these Excavator carriers are:
• Komatsu’s reputation for reliability and affordability
• Upsizing to the PC270-8 further improved the reliability
• The PC300LC-8 and PC400LC-8 have been very successful
• Guarding Packages suitable for all applications
• Including over-body and underbody of all different configurations
• Purpose Built Forestry Cabins which are approved by the regulators
• Load Sense Hydraulics that achieve the right output pressure
• Dedicated Return & Case Filters
• Aux cooler packages to suit very demanding applications
• Schedule 160 boom piping, 30% greater than most competitors
• Heavy Duty 600mm Double Bar or 600mm Single Bar Grousers
