Description
Now with a new technology Komatsu engine, our 40 tonne capacity HD405-8 truck is ideal for quarry, construction and small-scale mining operations. Advanced transmission and braking systems ensure optimum traction and the industry’s highest safety standards. As with all our trucks, key components are designed and manufactured by Komatsu to work together in an integrated package. And it comes standard with our KOMTRAX remote monitoring and location system, backed by our Australia-wide service and support network.
