EH AC-5 Series | Next-Generation Rigid Dump Trucks
The Evolved AC Drive Truck — Introducing the AC-5 Series
Building on the power and precision of AC Drive, the AC-5 adds comfort and efficiency to meet real-world demands.
Born from customer feedback, it’s the answer to “we wish it could do more.”
Climb confidently, descend with control — total haul speed.
With optimized torque and energy control, the AC-5 delivers stronger uphill performance than the AC-3. A high-capacity grid box and refined brake system support stable retarding during loaded downhill runs, maintaining consistent deceleration across long hauls. Compared with the AC-3, it improves speed both uphill and downhill, reducing total cycle time. Even in tough terrain, the AC-5 ensures reliable speed and control — boosting haul productivity.
Built to Carry More — Without Compromise.
The AC-5’s high-rigidity frame is engineered through advanced stress analysis to maintain stability under heavy payloads. Enhanced structural durability and optimized control systems ensure safe, efficient hauling. Compared with the AC-3, the AC-5 supports higher payloads without sacrificing speed or control — delivering maximum productivity across the haul cycle.
More output from every drop of fuel
The AC-5 enhances fuel efficiency without changing the engine. An adaptive twin-fan cooling system delivers just the right amount of cooling when needed—reducing unnecessary energy use. Selectable work modes help tailor performance to site conditions, optimizing fuel consumption. This balance of power and efficiency maximizes haulage per liter of fuel. Rather than simply saving fuel, the AC-5 turns every drop into greater productivity—supporting long-term gains in life cycle cost (LCC) performance.
The AC-5 brings every key performance factor — travel, braking, operability, and safety — to the next level.

1. Performance | Power Meets Efficiency
Advanced control systems deliver smooth starts and superior gradeability even under full load — all while improving fuel efficiency.
2 .Brake System | Trusted Braking for Heavy-Duty Loads
A single pedal controls both wet disc brakes and electric retarder. Smooth yet powerful deceleration improves safety and haul travel time.
3. Structure | Durability & Handling Reimagined
A newly reinforced high-rigidity frame, combined with proven trailing arms and NEOCON struts, delivers long life and smooth, stable travel — built strong, built flexible.
4. Operator Comfort | Stay Aware. Stay in Control.
Spacious cab, high-visibility displays, and intuitive layout ensure smooth operation, from driving to dumping to diagnostics — with less stress and greater comfort.
5. Safety | Built to Global Standards, Designed for Total Protection
The AC-5 is engineered in line with international standards, combining advanced visibility and protection features to safeguard operators, service personnel, and the entire site.
6. Hitachi Body | Engineered to Match, Built to Perform
Integrated with the truck for maximum stability and reduced structural stress.
Optional heated and application-specific designs meet diverse site needs.
