With Komatsu Hydraulic Mechanical Transmission (KHMT) – A unique solution for tomorrow challenges
Komatsu Europe presented a WA475-10 prototype at the bauma 2019 trade fair in Munich (April 8-14). Featuring the Komatsu Hydraulic Mechanical Transmission (KHMT), this next generation 24 tonnes class wheel loader is a versatile performer with an EU Stage V engine. Built on the recognized benefits of its predecessor, the WA475-10 is up to 30% more fuel-efficient and is perfect for any moving, transport or loading job with an outstanding combination of fuel efficiency, productivity and ease of operation.

At low engine speeds, the Komatsu EU-Stage V-compliant engine puts out high power and delivers more engine torque and performance. The aftertreatment system combines a Komatsu Diesel Particulate Filter (KDPF) and Selective Catalytic Reduction (SCR). The SCR system further reduces NOx emissions using AdBlue®. The engine’s advanced electronic control system manages the airflow rate and the fuel injection, combustion parameters and aftertreatment functions: performance is optimised, emissions reduced, and advanced diagnostic capabilities are provided.
KOMTRAX telematics and the Komatsu CARE customer maintenance program offer top fleet management and support, protect the machine against misuse and guarantee maximum efficiency and uptime.
Innovations and benefits
Komatsu Hydraulic Mechanical Transmission (KHMT) is an innovative Komatsu technology that makes the WA475-10 wheel loader more powerful and more fuel-efficient. A variable speed control allows to adjust the machine’s top speed, throughout the entire speed range, to the job-site’s requirements. The adjustable variable traction control effectively limits wheel spin in difficult ground conditions.
Power control on the brand new model includes a complete innovation: hydraulic speed can be independently controlled directly from the accelerator pedal. It has never been easier for an operator to find the right balance between traction and lifting power. The optimized Z-bar linkage system provides much more lift force and a higher tonnes-per-hour production rate. A remarkable lift speed and class-leading machine stability help to boost productivity, especially in narrow V-Shape loading applications. Furthermore, response time of the hydraulics and the dumping or lifting can be set to specific job-sites.
The new cab, more operator-friendly and spacious, has an internal noise level of just 70 dB(A). With only 4 pillars, its all-around glass surface contributes to perfect visibility. The lever console features a
new command-control dial and is adjustable on a 5x axis to suit any operator. A slightly increased internal air pressure prevents dust and other particulates from entering the cab. For easy and safe entering or exit, the WA475-10 is equipped with a rear-hinged door, angled steps and large handrails.
A 7-inch, full colour, high-resolution monitor provides key machine metrics including KDPF status and data for AdBlue® e-levels and fuel consumption. Messages from the ECO Guidance system are displayed in real-time during operations and on the exit screen when the ignition is turned off. The ECO guidance menu enables the operator to check operation logs and fuel consumption. These records are useful to reduce overall fuel usage, and can be saved and sorted by the operator.
The “Auto bucket-fill” and other features help the operator to maintain productivity even during long shifts.
A new air-suspension seat dampens vibrations to provide a more comfortable ride. Seat-mounted electronic pilot control levers, with the optional Komatsu Short-Lever-Steering System, improve convenience of operations and reduce operator fatigue.
Other features help to lower fuel consumption: The programmable Auto-Idle Shutdown system automatically switches off the engine when it is idle.
Cleaning and maintenance are easier than ever. The radiator has wider fin spacing, the cooling fan swings out and has a standard auto-reversing function. An electric tiltable engine hood provides full access to the engine compartment. Side doors give quick and convenient access for daily checks and service. Full rear fenders are standard, a gauge on the AdBlue® fill cap minimizes overfilling. Servicing costs are remarkably reduced, which provides a lower lifecycle cost.
