Komatsu’s HD325-7 and new 40-ton HD405-7 are designed for sand and gravel and rock quarry sites. Both trucks increase productivity while lowering fuel consumption. The HD405-7 is Komatsu’s newest 45-ton truck. The HD325-7 and HD405-7 both feature a powerful, clean SAA6D140E-5, Tier 3, turbocharged, after-cooled diesel engine that provides a maximum net output of 498 hp. Both trucks are equipped with the latest Komtrax fleet monitoring system which increases machine availability, reduces the risk of machine theft, allows for remote diagnosis by the distributor, and provides a wealth of other information to drive business efficiency and productivity.
The Komatsu designed electronically controlled countershaft transmission with K-ATOMiCS automatically selects the optimum gear according to vehicle speed, engine speed and the shift position chosen, resulting in the best gear for any operating condition. The optional automatic retard speed control system (ARSC) with a large capacity retarder allows operators to set downhill travel speed at a constant level.
