Increased productivity, improved access and all‐new operator environment.
The HD325-8 and HD405-8 are the latest additions to the Komatsu rigid frame truck family combine increased engine power and the Komatsu Traction Control System (KTCS) for improved productivity. They feature payload capacities of 36,5 and 40 metric tonnes respectively and replace the HD325‐7 and HD405‐7 models.
Both new trucks feature a EU Stage IV certified Komatsu SAA6D140‐7 engine that puts out 386 kW (518 HP). The latest engine technology from Komatsu also reduces fuel consumption. The optional Komatsu Traction Control System (KTCS) automatically applies the brakes independently to achieve optimum traction in varying ground conditions. Because the system operates without the need for differential lock‐up, steering performance is not compromised.
Jeroin De Roeck, Product Manager at Komatsu Europe says:
“With the integration of the latest Komatsu engine technology, the new HD325-8 and HD405‐8 are designed to offer a maximized productivity with a low operational cost. The new spacious and ergonomic operator cab, with fully adjustable, heated and ventilated operator seat, provides a first‐class, comfortable work environment.”
The latest KOMTRAX™ telematics, and the Komatsu Care® maintenance program, offer top fleet management and support, protect the machine against misuse and guarantee maximum efficiency and uptime.
Other new standard features for the two new trucks include a seven‐inch LCD colour monitor, a dedicated rear view monitor, fast‐fill fuel system and a premium heated and ventilated operator’s seat with air suspension. Front access is improved with sloped stairs and handrails, in place of the previous ladder configuration.
Standard features of the new HD325-8 AND HD405‐8:
Komatsu Engine Technology:
- The powerful SAA6D140‐7 engine provides 386 kW (518 HP).
