Komatsu’s new to Europe HM300-5 ADT

Komatsu’s new HM300-5 Articulated Dump Truck (ADT) is powered by a 242kW EU Stage IV emissions standard Komatsu SAA6D125E-7 engine. The HM300-5 has a maximum 28tonne payload and a body capacity (heaped) of 17.1m³. The ADT’s loading height is only 2.83m, which enables easy and quick loading.

Komatsu’s new to Europe HM300-5 ADT
2300 Komatsu’s new HM300-5 Articulated Dump Truck (ADT) is powered by a 242kW EU Stage IV emissions standard Komatsu SAA6D125E-7 engine.

The HM300-5 has a maximum 28tonne payload and a body capacity (heaped) of 17.1m³. The ADT’s loading height is only 2.83m, which enables easy and quick loading. Additionally, the two single-staged body lift cylinders provide a 70° dump angle. Selectable working modes allow the operator to choose between Economy and Power modes to tailor machine performance to the application or to work conditions.

The HM300-5 features the Komatsu Traction Control System (K-TCS) for automatic and optimum traction in soft ground conditions. As ground conditions worsen and tyre slippage is detected by speed sensors located on four wheels, the inter-axle is automatically locked. If tyre slippage continues, four independent brakes are activated to regain traction.

Another eye-catching feature of the HM300-5 is its use of K-ATOMiCS (Komatsu Advanced Transmission with Optimum Modulation Control System). K-ATOMiCS offers a six-speed, fully-automatic transmission that uses an advanced electronic system to eliminate shift shock and torque cut off to improve engine efficiency. It automatically selects the ideal gear based on vehicle speed, engine rpm and the shift position chosen. This results in powerful acceleration, smooth down-shifting and synchronized engine speed when climbing slopes. Operator fatigue is minimised, the load is kept in the body and productivity is increased.

A large automatic retarder allows the operator to select the optimum speed on downhill travel and fully loaded hauls, eliminating acceleration generated by the grade of the slope. An integrated Payload Meter (PLM) is available as an option on the HM300-5. It displays the weight of loaded material on a high-resolution LCD monitor for the truck operator, and indicates payload information to the loader operator via external display lamps. PLM data is also transferred via KOMTRAX and can be accessed by web.

The HM300-5’s Komatsu EU Stage IV engine uses an advanced electronic control system to manage the airflow rate, fuel injection, combustion parameters, and after treatment functions to optimise performance, reduce emissions, and provide advanced diagnostic capability. The result is lower fuel consumption with no loss of performance.

The HM300-5 provides easy service access in order to reduce costly downtime. The new truck has a light-weight fibreglass engine hood for easy access and increased cooling capacity.
