New Komatsu wheeled excavator
Komatsu Europe has revealed its new PW158-11 wheeled excavator. Weighing 16 tonnes, the PW158-11 short-tail excavator boasts factory-installed Quick Couplers, a swing tail radius of only 1,900mm, and can lift more than 5,000kg over the front or rear without a stabiliser. Operating weights range from 15,080kg to 18,240kg.
Its Stage 4 emissions-compliant Komatsu SAA4D107E-3 engine produces 122hp at 2,100rpm, and a Komatsu Diesel Oxidation Catalyst (KDOC) works together with the engine and other after-treatment components for improved efficiency and longer life. A new integrated Selective Catalytic Reduction (SCR) system further reduces NOx emissions by 80% using AdBlue, reckons Komatsu. There’s an Auto-Idle Shutdown system, too.
The boom suspension system (ECSS) provides a significant increase in comfort when travelling over bumps. The operator’s seat comes with suspended joystick consoles, premium cushioning, auto weight adjustments and pneumatic lumbar support. Joystick Steering (JSS) is provided as an option, while an upgraded high-resolution TFT-LCD widescreen colour monitor panel, with 25 built-in languages, provides key machine metrics including AdBlue e-level, fuel consumption, and performance data.
With its interface also visible on the monitor, Komatsu’s Attachment Control is integrated. Komatsu’s standard ‘KomVision’ enhances safety through a system of multiple cameras: jobsite surroundings can be checked on the monitor prior to carrying out any operation. For increased versatility, the PW158-11 can be equipped with either a truck type automatic hitch or a car ball type hitch, for a trailer up to 8 tonnes, with all necessary electric and hydraulic hook-ups. The trailer’s functions can then be operated from the cab’s joysticks.
The PW158-11 is also equipped with the Komatsu EMMS (Equipment Management Monitoring System), which has enhanced diagnostic features that give the operator and technicians greater monitoring and troubleshooting capabilities. EMMS also continuously monitors all critical systems, preventative maintenance, and provides troubleshooting assistance to minimise diagnosis and repair time. It can be accessed along with all essential machine functions on the cab’s monitor screen and set quickly. An optional ‘auto grease’ function, plus Komatsu’s wireless monitoring system ‘Komtrax’ boost the PW158-11’s appeal further still.
