Product catalog summary
Overview: The EH4000AC-3 is a high-capacity mining dump truck with a nominal payload of 221 tonnes and a gross machine operating weight of 384,000 kg. It utilizes advanced Hitachi AC Drive technology to enhance performance and reduce operational costs.
Engine Specifications: The truck is powered by a Cummins QSKTA60-CE engine delivering 1,864 kW (2,500 HP), with an optional MTU 16V4000 C21 engine available outside North America. Both engines are designed for high efficiency.
AC Drive System: The Hitachi AC Drive system improves truck performance with higher speeds, better gradeability, and efficient electric braking, reducing maintenance costs and increasing availability.
Structural Design: The truck's robust frame features a fabricated box section and rectangular frame rail construction, with horizontal stiffeners to minimize stress concentrations.
Suspension System: The trailing arm suspension system enhances maneuverability and reduces tire scuffing, while the NEOCON strut improves operator comfort and vehicle stability.
Safety and Monitoring: The HI-TECH ROPS/FOPS cab includes a Hitachi controller and a large LCD for system monitoring. The SkyAngle feature enhances safety with cameras positioned around the truck.
Maintenance and Management: Simplified maintenance is achieved through features like a fast filling system and remote machine management via Global e-Service for real-time monitoring and data analysis.
Weight and Load Distribution: The net machine weight is approximately 163,000 kg, with a weight distribution of 48% front and 52% rear when empty, shifting to 33% front and 67% rear when loaded.
Specifications: The truck includes a 1,950 kW engine, a reliable water cooling system, and a pressurized cabinet. The alternator has a capacity of 1,900 kVA, and the AC Wheel Motor consists of two units with a capacity of 765 kW each.
Axle and Tires: The axle has a planetary ratio of 35.3:1 with a maximum speed of 56 km/h. The standard tire size is 46/90R57.
Electrical System: Operates on a 24-volt system with heavy-duty batteries and alternators driven by either Cummins or MTU engines.
Body Capacities: The body has a struck capacity of 106 m3, with heaped capacities of 138 m3 and 154 m3 depending on the material density.
Steering and Hydraulic Systems: Features a closed-center, full-time hydrostatic power steering system with Hitachi accumulators and electronic controlled cushioning.
Brake System: Complies with ISO 3450 (SAE J1473) and includes service, secondary, parking, and electric brakes with a maximum dynamic braking capacity of 3,200 kW.
Operational Benefits: Adhering to the Hitachi Loading Policy ensures optimal performance, fuel economy, and maintenance efficiency.
Service Capacities: Specific capacities are provided for components like the crankcase, engine cooling system, and fuel tank.
Visibility and Equipment: Includes mirrors and cameras for ISO compliance, with optional equipment to enhance functionality and safety.
Dimensions: Detailed dimensions are provided for the empty machine with standard tires, noting variations based on tire specifications.
