2010 OPEN

As use of ICT for construction equipment became more common, things like crewless dump trucks, IT execution, and KOMTRAX were further developed. Hybrid equipment that decreased both fuel consumption and carbon dioxide emission was introduced and marked a new generation of construction machines.

Komatsu articulate dump truck HM300-3/HM400-3
(2012)

コマツ リオ・ティントで無人ダンプトラック運行システムの稼働を開始

HM300-3 and HM400-3 are newly launched articulate dump trucks that correspond 2011 off-road engine emission standards. They are equipped with the new generation engine that meets the emission regulation in Japan, North America and Europe. They reduce fuel consumption while improving loading mass, body capacity, engine output, retarder capacity and balance economy with superior environmental friendliness.

The deployment of Komatsu traction control system (KTCS) that enables them to run on slippery roads and soft surfaces, the anti slipping pin spike plates at the access point of the cab and the hand rail around the engine hood dramatically improved safety.
Shortening the nose of the body and placing the driver's seat in the center of the cab provided an improved and wider view to the right and left. The color rear view monitor is installed as standard equipment, which improves safety. The 7-inch HD LCD monitor with eco-guidance function supports energy saving operation.

Maximum loading mass: 28.0t (HM300-3)

Dump truck OPEN

The history of the dump truck as a transporting vehicle is also the history of increasing the amount of loading to improve productivity at construction sites. At mines especially, new technology is being introduced consistently even today. Enlarging the size by mechanical and electrical formulas, and adding the GPS control system are some of the examples.
