Hitachi Construction Machinery has introduced the EH4000AC-5, which it claims is a revolutionary rigid dump truck specifically for the mining industry. 

With a payload capacity of 242 tonnes and a gross machine operating weight of 427 tonnes, this model incorporates advanced technologies for operator comfort, safety and sustainability. 

Hitachi has engineered the EH4000AC-5 using advanced metal fabrication techniques derived from its hydraulic excavator manufacturing expertise. 

Compared to its predecessor, the EH4000AC-3, the new model boasts an additional 21 tonnes of payload capacity. 

Reinforced structural durability ensures long-term reliability even in extreme operating conditions.

The EH4000AC-5 features an optimised driving system that ensures stable performance, even under full load. 

With a maximum speed of 65 km/h, the truck offers exceptional transport efficiency. 

Operators can choose from three driving modes; High Power Mode, Power Mode, and Eco Mode, to adapt to different site conditions. 

High Power Mode enhances productivity, while Eco Mode minimises fuel consumption for more cost-effective operations.

Hydraulic brakes have been enhanced with wet brakes in the front, while retarder auxiliary brakes deliver better stopping performance. 

These enhancements ensure stable and safe braking in challenging environments, reducing wear and tear on critical components.

The operator cabin of the EH4000AC-5 has been completely redesigned to improve usability and comfort. 

The switches and monitors within the cab are arranged to ensure smooth operation. 

Key safety and operational information, such as loading status and safety conditions, are displayed on monitors, providing the operator with essential data at a glance. 

The ergonomic design creates a comfortable working environment, enabling operators to perform efficiently during extended shifts.

Aligning with global trends in sustainable mining, the EH4000AC-5 includes a fully-electric specification. 

This advanced system integrates batteries and trolley dynamic charging capabilities, allowing the truck to use power from overhead lines installed at mines. 

By reducing reliance on traditional fuel sources, the truck offers a cleaner, more environmentally- friendly solution, the manufacturer says.
