Marubeni-Komatsu announces the new PW148-11 and PW180-11 wheeled excavators. Ideal on job sites with limited space or in urban areas, these compact machines are versatile tools packed with new features, with a powerful EU Stage IV engine and up to 13 % lower fuel consumption.
Built on the recognized benefits of their predecessors, with the same basic machine dimensions, linkage, and main hydraulic valve, the Komatsu PW148-11 and PW180-11 propose advancements in design and technology that improve their versatility, efficiency and operator comfort.
“A lot of work went in to the redesign of Komatsu’s dash 11 wheeled excavators, with a dramatic increase in versatility for customers” says Sebastian Zienau, Product Manager at Komatsu Europe. “Joystick steering, an integrated system for controlling tools and the factory- installed quick couplers also boost performance and efficiency”.
KOMTRAX telematics and the Komatsu Care maintenance program, offer top fleet management and support, protect the machines against misuse and guarantee maximum efficiency and uptime.
Komatsu EU Stage IV Engine: Less fuel and cleaner air.
Both excavators have a new powerful and cleaner Komatsu EU Stage IV engine.
Operating weights of the PW148-11 range from 14.200kg – 17.160kg. Its Komatsu SAA4D107E-3 engine outputs 90 kW / 121 HP, at 2100rpm, and a Komatsu Diesel Oxidation Catalyst (KDOC) works together with the engine and other after-treatment components for improved efficiency and longer life.
The heavier PW180-11 features operating weights from 17.600kg – 20.600kg, a Komatsu SAA6D107E-3 engine and 123 kW / 165 HP, at 2000 rpm. A Komatsu Diesel Particulate Filter (KDPF) captures over 90% of diesel particulates and prevents their release in the atmosphere.
On both machines, the new integrated Selective Catalytic Reduction (SCR) system further reduces NOx emissions by 80% using AdBlue®. The engines’ electronic control system manages the air-flow rate and the fuel injection, combustion parameters and aftertreatment functions: along with ultra-low emissions, performance is optimised.
Advanced diagnostic capabilities are also provided.
The new Auto-Idle Shutdown system prevents unnecessary fuel consumption: it will automatically shut the engine off and apply the parking brake and hydraulic lock after a pre-set idle time limit. The new viscous fan clutch that controls optimal cooling fan speed also reduces fuel consumption and contributes to lower in-cab noise.
Versatility and comfort
A new 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, for outstanding operator comfort and control, with new and easy-to-use operation switches.
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 PW148-11 and PW180-11 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 excavators are equipped with the exclusive 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 in the blink of an eye.
The AdBlue®. tank can be refilled from a walking platform close to ground level, and both the refueling and the auto lubrication pumps were relocated to be more accessible. HCU piping layout was standardized to be the same on all new PW148, PW160 and PW180 machines.
Komatsu machines are designed for easy maintenance and the PW148-11 and PW180-11 are no exception. An “auto grease” function can be ordered, and regular engine service points, greasing points and filters are centralized, and are quickly and safely accessible.
