D475A-8E0 Komatsu D475A-8E0 Specifications & Technical Data (2021—2026)

Large TFT colour multi monitor

A large user-friendly colour monitor enables safe, accurate and smooth work. It provides on-hand data to continuously improve productivity and fuel consumption. Multilingual and with all essential information available at a glance, it features simple and easy to operate switches and multifunction keys that provide the operator with fingertip access to a wide range of functions and operating information.

Widescreen monitor

Conveniently customisable and with a choice of 26 languages, the widescreen monitor with simple switches and multifunction keys gives fingertip access to a large range of functions and operating info.

Equipment management support

KOMTRAX Plus enables expanded monitoring of the fleet via satellite and wireless LAN. Users can analyze “machine health” and performance from a remote location, on a near-real time basis. This includes component condition and trend data. By making this critical information readily accessible, KOMTRAX Plus is an effective tool in maximizing productivity and lowering operating cost.

Emergency engine stop switches

These switches instantly stop the engine. One is installed in the cab, the other at the right rear of the machine.

One side platform

Allows safe access to rear maintenance points. Check and refilling of fuel and washer fluid, cleaning of cab window glass and air conditioner condenser, cab lights, etc., can be safely performed.

Self-diagnostic monitor

The multifunction monitor panel displays the running time, engine revs, fuel level and water coolant temperature in real time. It also provides the operator with maintenance and service information, if oil filters need replacing or any abnormality occurs. In addition, it supplies Komatsu mechanics with detailed information, with no need for external service tools.

Heavy-duty aftertreatment

The Komatsu Diesel Particulate Filter (KDPF) captures more than 90% of Particulate Matter (PM). Special oxidation catalyst and extra fuel injection in the exhaust stream can decompose accumulated soot in the KDPF filter by either active or passive regeneration. This system doesn’t require operator intervention, and won’t interrupt normal operation.

Swing-out radiator grill and reversible fan

The radiator can be easily cleaned by utilisation of the reversible, hydraulically driven cooling fan from a touch on the monitor panel.

Modular power train

All the power train components are enclosed in a sealed module. This eliminates oil spills during mounting and dismounting, and prevents dust and dirt polluting individual components. Servicing is much cleaner, smoother and easier.

12% More Power in Reverse

A powerful and fuel-efficient engine, compliant to EU Stage V emissions regulations, makes the D475A-8 an outstanding performer, both for dozing and ripping. Engine output is increased by 1.12 times when in reverse, with a faster climbing speed in downhill dozing. Cycle times are reduced and production is improved drastically.

Automatic Transmission

Set by default, the D475A-8 has a highly efficient transmission that automatically matches the best gear mode in all dozing operations and includes a travel speed preset function to reduce work time and fatigue for the operator. With Komatsu’s ECMV (Electronic Controlled Modulation Valves), gear changes are smoothly timed to always keep the power transfer at maximum efficiency.

Torque Converter with Auto Lock-Up

Combined with the automatic transmission, the Komatsu automatic lock-up torque converter reduces fuel consumption by up to 10% by eliminating unnecessary power loss. When required, the powertrain control system engages the torque converter or locks it up to send full engine power directly to the transmission during less torque demanding applications.

Gearshift Preset Function

To reduce the frequency of gear shifting and for comfortable machine operation, a shift preset mode is provided as standard equipment. The preset switch lets the operator select a combination of forward/reverse gear shifts by using the UP/DOWN shift switch on the steering lever. Once the shift pattern is selected, only forward/reverse direction control selection is required for a correct gear shift.

Auto-Downshift

The engine controller continuously monitors the engine speed, travel gear, and travel speed. When a load is applied and the machine slows, the controller automatically downshifts, optimizing the gear speed for the best dozing performance. This function enables comfortable operation and high productivity without manual downshifting. It can be deactivated by a cancel switch on the monitor panel.

Selectable Working Modes

Working mode can be set to either “Power” for maximum power or to “Economy” for energy saving operations. Combined with a choice between automatic or manual working mode, this lets the operator select the optimum machine power configuration for the work at hand.

Adjustable Idle Shutdown

To reduce unnecessary fuel consumption and exhaust emissions, and for lower operating costs, the Komatsu auto idle shutdown automatically turns off the engine after it idles for a set period of time, which can be easily programmed from 5 to 60 minutes. An Eco-gauge and Eco guidance tips on the cab monitor further encourage efficient operations.

Track Shoe Slip Control System

This system removes the need to continuously control the engine power output with the decelerator pedal while ripping; the output automatically adjusts to the optimum level. This substantially reduces fatigue, letting the operator concentrate on the ripping without having to monitor track shoe slippage. Less track shoe slippage also means lower undercarriage operating cost and lower fuel consumption.

Sturdy, rugged design

A high-rigidity hull structure main frame improves durability and reduces stress concentration at critical areas. The track frame with a large cross section utilises pivot shaft mounting for greater reliability. All hydraulic piping is robustly protected by cover and inner route to ensure damage protection from materials.

K-Bogie undercarriage system

The K-bogie undercarriage is built with an oscillating idler and with flexible mounted bogie systems that allow a high vertical track roller movement. The oscillating idler combined with the 8 track roller/K-bogie design supports and guides the undercarriage on all ground conditions for a much smoother drive and a longer undercarriage life.

Quiet and comfortable cab

Operator comfort is essential for safe and productive work. The newly designed cab on the D475A-8 is quiet and comfortable, an ideal environment to concentrate on the job. Its hexagonal design and large tinted glass windows offer excellent panoramic visibility. The high capacity climate control system pressurises the cab to keep dust out. A high quality sound-absorbent lining covers the interior to minimise noise levels for the operator.

Optimal jobsite safety

Safety features on the Komatsu D475A-8 comply with the latest industry standards and work in synergy to minimise risks to people in and around the machine. Highly durable anti-slip plates – with additional high friction covering – maintain long term traction performance. A seat belt caution indicator and an audible travel alarm further increase jobsite safety.

Komatsu blades

For increased blade performance and better machine balance, Komatsu uses a box blade design, with the highest resistance for a light weight blade. Special Komatsu highly wear resistant steel is used for the front and sides of the blade to increase durability. The deep curved design of the blade makes it easy to handle a wide range of materials, with good penetration and a large capacity, optimising high dozing performance with excellent fuel efficiency.

Semi-U blade

The Komatsu Semi-U blade will stand up to the toughest applications. The shape of the blade improves carrying capacity, minimizes shoe slippage and increases productivity. Its two side wings prevent material spillage and offer a class-leading performance when dozing.

U blade

The Komatsu U blade was specially designed to handle large quantities of material with a minimum of spillage. Along with a large capacity this outstanding blade also has a good rolling performance, and helps to get the best out of the machine.

Komatsu rippers

Komatsu’s patented ripper concept, with all cylinders connected to the ripper shank holder, allows maximum pry-out force. Its key feature is the ripper point movement that lifts the material during the ripper shank operation to greatly improve overall performance. The shank supplies great penetration into various types of materials and is fitted with special wear parts for increased longevity.

Automatic blade pitch and ripper return

To reduce operator effort and increase efficiency while dozing, a new “auto pitch” mode, triggered by a simple switch, sets the blade pitch between “digging” and “dump” positions. Additionally, a new ergonomic ripper control lever with an auto-return function automatically raises the ripper when moved into reverse.

Superior visibility on blade and ripper

The redesigned ROPS/FOPS integrated cab and the well-located operator seat give optimal blade visibility to the left and right and make both dozing and grading easy, safe and fast. Thanks to the new ripper arm structure, the visible area of the ripper shank is drastically enlarged. The operator can accurately position the front edge of the shank and hard rock is ripped easily.
