Komatsu's technology focus

Komatsu will introduce the third generation of its hybrid excavators at Intermat, in the form of the 22.6 tonne HB215LC-2.

Since introducing hybrids in 2008, Komatsu says it has sold 2,500 such machines worldwide, and that average fuel savings come in at 25% compared to a traditional machine.

The new hybrid features a Stage IIIB engine and updated hybrid technology, which Komatsu says translates into better fuel economy, particularly when using the excavator with hydraulic attachments.

In a different technology area, Komatsu will use the show to introduce its new PC210LCi-10 intelligent machine control excavator, which is designed to improve efficiency by preventing the operator from digging too deep or damaging the target surface.

Operating weights range from 22.6 to 23.5 tonnes, depending on the configuration, and other specifications are identical to those for the standard PC210LC-10.

More traditional new models on show will include the Stage IV-compliant 24 tonne class PC240LC-11 tracked excavator, which the company says offers 6% better fuel efficiency than the previous model. All Komatsu Stage IV machines come with Komatsu CARE®, a complimentary maintenance programme covering the first three years or 2,000 hours for factory-scheduled maintenance, performed by Komatsu-trained technicians and genuine parts. It also includes a maximum of 2 complimentary diesel particulate filter (DPF) exchanges and a warranty on these parts for the first 5 years or 9,000 hours. There is also a 5 year/9,000 hours warranty on the SCR body.

Further down the weight classes is the new 8.5 tonne class PC88MR-10 tight tail swing crawler excavator, which Komatsu says offers improved efficiency, lower fuel consumption, improved operator comfort and enhanced serviceability.

It offers a maximum digging depth of 4.6 m and a maximum reach of 7.1 m. A swing boom allows the PC88MR-10 to work in confined spaces so the operator can focus on the work in front of the machine and worry less about rear swing impact in confined areas.

New in Komatsu’s dozer range at intermat is the D65-18, which is available in three undercarriage variants – standard (EX), low ground pressure (PX) and wide (WX). The unit weighs in at 20.5 to 24.9 tonnes depending on configuration, and is powered by a Stage IV 162 kW Komatsu engine.

The new transmission features a lock-up torque converter, which the company says can reduce fuel consumption by 10%, and this can be set to either automatic or manual mode.

The standard blade is Komatsu’s sigmadozer design, which the company says improves performance and productivity by up to 15% compared to conventional designs. A six-way Power Angle Tilt (PAT) blade is available as an option.

Further up the weight range is the new 264 kW Stage IV-engined D155AX-8 dozer, which weights 38 to 43 tonnes, depending on configuration. Again, the sigmadozer blade is standard for up to 15% more production over conventional blades, and the transmission also features the fuel-saving lock-up torque converter.

Launched last year in the US, but new to Europe is Komatsu’s HM300-5 articulated dump truck (ADT), which offers a 28 tonne payload and is powered by a 242 kW engine.

The truck features the Komatsu Traction Control System (K-TCS), which automatically locks the inter-axle if slippage is detected. Also on-board is the painfully titled Komatsu Advanced Transmission with Optimum Modulation Control System (K-ATOMiCS), which provides offers a six-speed, fully-automatic transmission with electronics to eliminate shift shock and torque cut-off to improve engine efficiency.

Finally, Komatsu will present a new wheeled loader in the shape of the Stage IIIB-compliant 115 kW WA270-7. The 13.5 tonne machine features more engine power, lower fuel consumption, improved operator comfort, and easier serviceability than its predecessor, according to Komatsu.
