Komatsu Technology

Komatsu develops and produces all major components, such as engines, electronics and hydraulic components, in house.

With this “Komatsu Technology,” and adding customer feedback, Komatsu is achieving great advancement in technology.

To achieve both high levels of productivity and economical performance, Komatsu has developed the main components with a total control system.

The result is a new generation of high performance and environment friendly machines.

High Performance Komatsu SAA6D125E-5 Engine

Powerful turbocharged and air-to-air aftercooled Komatsu SAA6D125E-5 engine provides 254 kW 340 HP. This engine realizes high power in low fuel consumption with Common Rail Injection system (CRI), and thus it delivers higher travel speeds with high horsepower.

Also high torque at low speed, impressive acceleration, and low fuel consumption ensure maximum productivity.

Engine Power Mode Selection System

The system allows selection of the appropriate mode between two modes or according to each working condition. The mode is easily selected with a switch in the operator’s cab.

Power mode: Great productivity can be attained by taking a full advantage of high output power. It is appropriate for job sites where larger production at uphill-hauling is required.

Economy mode: Engine speeds of the maximum output, downshift, and upshift are set to a lower level. It is appropriate for light work on the flat ground.

Komatsu Designed Electronically Controlled Countershaft Transmission

The Komatsu designed Electronically Controlled Transmission called K-ATOMiCS has been a success in Komatsu’s rigid dump trucks. The electronic clutch modulation system ensures proper clutch pressure when the clutch is engaged. The total control system controls both the engine and transmission by monitoring the vehicle conditions. This high technology system assures smooth shifts without shock and maximizes power train life.

Komatsu Designed Differential Locking Systems

The full-time six-wheel drive system reduces slippage. A wet multiple-disk interaxle clutch also locks the three axles in unison for greater traction. The interaxle lock can be switched on and off while the truck is travelling, thereby boosting productivity. In addition, limited slip differentials prevent the tires on either side from slipping on soft ground.

Hydro-pneumatic Suspension

Hydro-pneumatic suspension with proven performance in larger articulated and rigid trucks is tailored for use in the HM300. 

The front axle hydro-pneumatic suspension employs "De Dion" type design, allowing the machine to ride more smoothly over bumps. The rear-axles are mounted on a dynamic equalizer structure equipped with hydro-pneumatic suspension. The entire vehicle’s suspension delivers a comfortable ride and maximizes productivity.

Hydraulically Controlled Wet Multiple-Disc Brakes and Retarder

Wet multiple-disc brakes with proven performance in larger articulated and rigid trucks are tailored for use in the HM300. The large-capacity, continuously cooled, wet-multiple disc brakes also function as a highly responsive retarder which gives the operator greater confidence at higher speeds when travelling downhill.

Retarder Absorbing Capacity (continuous descent): 370 kW 496 HP

Large Capacity Body and Box Section Frame Structure

The HM300 has the large heaped capacity of 16.6 m3 21.7yd3 body. The low loading height of 2790 mm 9’2” enables easy loading. The body is built of high strength wear-resistant steel with a Brinell hardness of 400, and the body shape provides excellent load stability. Rugged enough for the toughest jobs, the HM300’s frame is designed using a rigid box structure with connecting torque tubes made of high strength low alloy steel.

Articulated Steering

Fully hydraulic articulated steering offers low-effort operating performance and maneuverability. A minimum turning radius of only 7.96 m 26’1” provides ability to work in tight areas.
