ECOLOGY & ECONOMY

Komatsu SAA4D95LE-5 is low fuel consumption by total control of the engine, hydraulic and electronic system.

Compact and lightweight engine with high power.

Thermal efficiency by better combustion conditions.

Minimal power drop at high altitude

The newly-developed Komatsu engine enables NOx emissions to be significantly reduced. This engine is U.S. EPA Tier 3 and EU Stage 3A emissions equivalent, without sacrificing power or machine productivity.

To prevent unnecessary fuel consumption, an idling caution is displayed on the monitor, if the engine idles for 5 minutes or more.

Engine speed automatically slows down when all control levers are set in neutral.

Due to Komatsu’s excellent hydraulics tuning technology, the machine satisfies both requests for powerful operation and fine controllability. Operator can control at will and can work efficiently.

Two established work modes are further improved.

- P mode – Power mode gives priority to work, while maintaining fast equipment speed and maximum production and power.

- E mode – Economy mode reduces fuel consumption. Speed of work equipment is almost same as P mode for light duty work.

Operator can select Power or Economy mode using a onetouch operation on the monitor panel depending on work load. In addition, operator can select E0 or E1 mode within E mode depending on work load. The power output will be reduced when adjust E0 to E1, however, the fuel consumption will be better

The ECO gauge on the right side of the multi-function color monitor provides environment-friendly energy-saving operation. Focus on operation in the green range allows reduction of CO2 emissions and efficient fuel consumption

COMFORT

Cab is highly rigid and has excellent sound absorption ability. Improvement of noise source reduction and use of low noise engine, hydraulic equipment, and air conditioner allow this machine to generate a low level of noise.

Spacious cab has wide glass area to provide the operator with excellent visibility.

Newly designed large cab provides roomy work space and wide legroom. In addition, large operator’s seat has a fore-and-aft sliding and a reclining function.

The automatic A/C has a bi-level control function to keep cool and warm respectively. This improved air flow function keeps the inside of the cab comfortable from top to bottom throughout the year. Defroster function keeps cab glass clear.

The machine is equipped with a ROPS cab (ISO 12117-2) for excavators as standard equipment. The ROPS cab has high shock-absorption performance, featuring excellent durability and impact strength. It also satisfies the requirements of OPG top guard level 1 (ISO 10262) for falling objects. Combined with the retractable seat belt, The ROPS cab protects the operator in case of tipping over and against falling objects.

A large user-friendly color monitor enables safe, accurate and smooth work. Improved screen visibility is achieved by the use of LCD that can easily be read at various angles and lighting conditions. The switches are simple and easy to operate. Industry first function keys facilitate multi-function operations. Displays data in 12 languages to globally support operators around the world.

Rear view mirror allow Komatsu PC70-8 to meet the visibility requirements (ISO 5006).

Locks the hydraulic pressure to prevent unintentional movement. Neutral start function allows machine to be started only in lock position.

Monitor function: Controller monitors engine oil level, coolant temperature, battery charge and air clogging, etc. If the controller finds any abnormality, it is displayed on the LCD.

Maintenance function: Monitor informs replacement time for oil and filters when the replacement interval is reached.

Trouble data memory function: Monitor stores abnormalities for effective troubleshooting.

MAINTENANCE

Operator can open all covers wide. It is very easy to access key components and filters. Also it is very easy to check oil.

Engine oil filter, engine main fuel filter and fuel drain valve are remote mounted to improve accessibility.

Since radiator, aftercooler and oil cooler are arranged side-by-side, it is easy to clean, remove and install them. Radiator, aftercooler, and oil cooler made of aluminum have high cooling efficiency and are easily recycle

Tool box is located on right side of cab. Capacity is large to store a tool kit and a pail can

Removes water and contaminants in the fuel to prevent fuel problems. (With built-in priming pump)

The A/C filter is removed and installed without the use of tools facilitating filter maintenance

Air cleaner and double element prevent dust from entering the system.

Uses high-performance filtering materials and long-life oil. Extends the oil and filter replacement interval

Revolving Frame with Undercover

Seven undercovers protect inner components from objects thrust up from the bottom.

Exterior parts are easy to repair

Outside diameter is 118 mm. Large rollers provide longer life.

High reliability, due to thickening plate significantly

This travel motor uses planetary gear. Structure is simple and reliable.

SPECIAL SPECS.

Komatsu Genuine Attachment Tool

Komatsu-recommended attachment tools for hydraulic excavators. A wide range of attachment tools are provided to suit customers’ specific applications

Hydraulic breaker

The hydraulic breaker is an attachment tool used for crushing rock beds and paved surfaces, demolishing concrete structures, etc. The large gas chamber, ideal gas pressure ratio, and long-stroke piston deliver
a powerful impact force. Since the breaker unit does not require an accumulator, the number of parts has been reduced, resulting in lower maintenance costs.

Crusher

This attachment tool is used for demolishing concrete structures. Since it does not have a striking mechanism and features low noise and low vibration, it is suitable for work in urban areas. The openclose cylinder is equipped with a speed-up valve for increasing work speed.
