1 hm400 1. hm400 -1 Articulated Dump Truck . Hiroyuki Igusa 1 hm400 . 2001 5 6 . hm400 1 . The market had strongly requested Komatsu to develop articulated dump trucks by itself. We developed the first model, the hm400 -1, and put it on the Japanese market in May 2001 and on the USA market (which was the main market) in June 2001. In this paper, we will introduce the main features of the hm400 -1 which has outstanding performance and durability as a construction machine based on our technologies. Key words: Articulated Dump Truck, Outstanding Productivity, Outstanding Reliability, Differential Lock, Interaxle Differential Lock.
