Komatsu America Corp.'s HM300-5 articu-
lated dump truck boasts 324 net horsepower
and is powered by a Tier 4 Final Komatsu
SAA6D125E-7 engine. The truck is said to
deliver high levels of performance while reduc-
ing fuel and operating costs. It has a 30.9-ton
payload and a gross vehicle weight of 117,892
pounds. Through body design optimization,
the truck has increased body capacity and
payload. The low 9-foot, 2-inch loading height
matches with 30- to 60-ton excavators or
5- to 7.5-cubic-yard wheel loaders. Economy
and Power modes allow the operator to tai-
lor machine performance to work conditions.
Komatsu Advanced Transmission with Optimum
Modulation Control System (K-ATOMiCS) uses
an advanced electronic system to shift shock
and torque cutoff to improve operator and en-
gine efficiency.
