Introduction
Hitachi's mechanical-drive diesel trucks are designed for small to mid-size quarry and mining operations, offering a balance of economy and performance. They are known for their serviceability and use of traditional diagnostics.

Engine and Transmission
The trucks are powered by Detroit Diesel (DDEC Series 2000) or Cummins Quantum engines, known for reliability and efficiency. The Allison transmission, controlled by the Commercial Electronic Control (CEC II) system, is remote-mounted for easy access and serviceability.

Braking and Suspension
Hitachi trucks feature wet-disc rear brakes and dry-disc front brakes for long service life. The Accu-Trac suspension system with Neocon-filled struts provides superior stability and minimizes frame fatigue.

Frame and Design
The trucks have a strong frame and suspension, with a design that distributes stress evenly. The frame is wider at the rear for better load support, and the "horse-collar" design allows for easy engine access.

Operator Comfort and Safety
The Command Cab III offers enhanced operator comfort with sound-absorbing materials, a wraparound dashboard, and a full suite of controls and monitoring systems. Hydrostatic power steering provides excellent control.

Hydraulics and Maintenance
The hydraulic hoist system is designed for durability, with a separate reservoir and electronic control. Maintenance is simplified with easy access to components and fewer lubrication points.

Legacy and Support
Hitachi's acquisition of Euclid and their solid dealer network ensure reliable support and availability of parts. Remanufactured components are available, backed by a warranty.

Conclusion
Hitachi's commitment to quality and innovation is evident in their mechanical-drive trucks, designed to maximize productivity and minimize downtime.
