The recently introduced Komatsu HM300-3 articulated truck
It features a gross vehicle weight 52,230kg with a payload of 28.1tonnes at its maximum ground speed of 58.6km/hour.
For the engine, Komatsu has developed a hydraulically actuated Komatsu Variable Geometry Turbocharger (KVGT) and an Exhaust Gas Recirculation (EGR) valve, which is said to result in better precision and air management as well as longer component life. The Komatsu Diesel Particulate Filter (KDPF) has an integrated design that will not interfere with daily operation but keeps the operator aware of its status.
The HM300-3 features the new Komatsu Traction Control System (K-TCS), which automatically provides optimum traction when operating in soft ground conditions, and it is enhanced with K-ATOMiCS (Komatsu Advanced Transmission with Optimum Modulation Control System), which offers a six-speed, fully-automatic transmission that uses an advanced electronic system to eliminate shift shock and torque cut-off to improve operator and power train efficiency.
“The low 2,820mm loading height easily matches with 30-60tonne hydraulic excavators or 5yd³ [3.8m³] to 7.5yd³ [5.7m³] wheel loaders,” says Komatsu.
With a new cab design and easy service access, the machine is equipped with the Komatsu EMMS (Equipment Management Monitoring System), offering greater monitoring and troubleshooting capabilities, and KOMTRAX, which provides daily machine information through a secure website utilising wireless technology.
