PW118MR-8 Komatsu Excavator Specs & Dimensions - (2012 - 2017)

Walk-Around

The new PW118MR-8 compact midi-excavator is the result of expertise and technology that Komatsu has developed from over 80 years’ experience. Developed with constant attention to the needs of customers all over the world, the PW118MR-8 is a user-friendly machine that delivers top-class performance. It has a tight tail swing and protrudes over the wheels by just 190 mm. So the operator can concentrate on the work in front, without having to worry about rear-swing impacts.

Work in tight spaces

The short-tail PW118MR-8 delivers optimal power and digging speed, even in confined spaces where traditional machines can’t work: yards, road works, demolition sites, sewers, etc. Sturdy and very stable, it guarantees maximum safety and offers complete operator confidence in any working conditions.

Engine

High torque and fuel efficient Komatsu ecot3 engine Meets EU Stage IIIA and EPA Tier III Auto-deceleration and eco-gauge for a lower fuel usage 5 selectable working modes Low operating noise levels

Performance and ecology

The PW118MR-8 is fitted with an ecot3 engine that meets EU Stage IIIA regulations. Together with an advanced hydraulic system, this electronically controlled common-rail engine with multi stage injection achieves a superior level of productivity. Drastically reduced NOx emissions and noise levels make this compact excavator perfect for confined areas and urban jobsites.

High productivity and fuel saving

Depending on the load, operators can conveniently choose between 5 working modes designed to match engine speed, pump delivery and system pressure. Priority can be given either to speed, for more productivity, or to fuel consumption for lighter applications. Fuel efficiency is further improved with the auto-deceleration, a standard feature that automatically slows down engine speed when levers are in neutral position, and with the eco-gauge, visible on the LCD monitor.

Engine specifications

Komatsu SAA4D95LE-5 common rail, multi injection, water cooled, turbocharged diesel engine, EU Stage IIIA/EPA Tier III compliant Alternator 24 V / 60 A.

Excellent travel performance

Wheeled excavators are built to move quickly on and between jobsites. To increase its mobility, the PW118MR-8 features a completely reworked driveline for faster travel and uphill driving speeds. The front oscillating axle, manually lockable through the LCD monitor, further increases the performance on slopes.

4-wheel steering

It’s possible to select between 3 steering modes: 2-wheel steering (for travelling), 4-wheel steering (for fast, agile operation) and crab (for confined areas). This ensures outstanding versatility and manoeuvrability. It’s easy and safe to change the steering mode: just push 2 switches at the same time on the new panel, and a green lamp will inform you of the steering mode selected. When working, the front-axel oscillation can be blocked for improved stability.

Hydraulic system

5-working mode selection system; Power mode, economy mode, breaker mode, attachment mode and lifting mode. One additional 2-way full-flow service valve with hydraulic line for attachment on boom and arm (HCU-A). Additional auxiliary hydraulic circuit (HCU-B). Relief valve on service spool. 2nd auxiliary hydraulic circuit (HCU-C) + preparation for hydraulic quick-coupler. Final lock valves on attachment circuit.

Cab

Spacious and comfortable cab ROPS compliant with ISO12117-2:2008 Quiet and ergonomic working environment Large multifunction colour LCD monitor Sliding door for easy entry and exit Automatic air conditioner Adjustable seat with safety belt Radio pre-setting 12V electric plug Radio Rain visor.

Operator's environment

The PW118MR-8 has a spacious ROPS cab (ISO 12117-2) designed to absorb shocks and offer maximum protection in case of a roll over. It also gives outstanding comfort to this compact machine, even to the most demanding operator. With a double slide mechanism, the seat and PPC levers can be conveniently adjusted for maximum productivity and minimum fatigue. Wide front and side windows - and an opening skylight - enable better visibility in any situation. The standard automatic air conditioner completes a comfortable work environment by maintaining a perfect temperature in the cab, no matter the weather outside.

Large multifunction LCD monitor

A large and user-friendly colour monitor makes working in a PW118MR-8 safe, accurate and smooth. Its highly intuitive interface and easy-to-operate switches give the operator access to a huge range of functions and operating information.

Lighting system

Optimal Maintenance Layout

Optimal maintenance layout Side-by-side coolers Equipment Management and Monitoring System (EMMS) Standard fuel pre-filter with water separator Long maintenance intervals

EMMS (Equipment Management and Monitoring System)

Komatsu’s EMMS can prevent a small problem from becoming a major service issue. The controller monitors all critical systems and key engine features such as engine oil pressure, coolant temperature, battery charge, air clogging etc. If an abnormality occurs, it is displayed on the LCD. The monitor also indicates when the oil or the filters must be replaced.

Safety equipment

Overload warning device Travel acoustic alarm Horn Rear-view mirrors (left side, rear) Hose burst valve on boom cylinder Rotating beacon Arm safety valve.

Excellent serviceability

Komatsu designed the PW118MR-8 with an easy access to all service points. Routine maintenance and servicing are less likely to be skipped, which can mean a reduction of costly downtime later on. The radiator, aftercooler and oil cooler are made of aluminium to improve their efficiency and are mounted in parallel for quicker cleaning. The fuel and oil filters as well as the fuel drain valve, are all remote mounted and easily accessible.
