Hitachi Construction Machinery has implemented a full-model change of the EH4000AC-3 rigid dump truck to develop the EH4000AC-5 (nominal payload of 242t, gross machine operating weight of 427t).

By applying metal fabrication technologies accumulated through the manufacturing of hydraulic excavators, the company increased the durability of the machine, with a payload of 242t. This is a payload increase of 21t compared to the EH4000AC-3.

The EH4000AC-5 evolved the Hitachi AC drive system cultivated through the current EH AC3 series models and strengthened the brakes, suspension and other aspects of the undercarriage to achieve smooth, stable driving and deceleration performance. In addition, the change to a fully electric specification equipped with batteries and trolley dynamic charging systems that receive power from overhead lines installed at mines is also compatible with the EH4000AC-5 similar to the current EH-AC3 series models.     

With a maximum speed of 65 kph, the truck is equipped with a new feature that allows operators to select from three different driving modes (High Power Mode, Power Mode and Eco Mode) according to the site environment. Operators can select Eco Mode when they wish to reduce fuel consumption or High Power Mode to maximize driving performance. In terms of the deceleration performance, braking capabilities were updated by changing the hydraulic brakes from front dry brakes to wet brakes and adjusting the retarder auxiliary brakes.

Information regarding the safety conditions around the machinery, loading conditions and more is displayed on the monitors to support safe operation by customers.

The EH4000AC-5 is compatible with the Consite Mine service solution which remotely monitors the status of mining machinery. Consite Mine issues two types of reports consisting of "Scheduled Reports" that inform customers of the machines' operational status via email and a smartphone app and "Alarm Reports" that are issued whenever various sensors detect abnormalities in the machinery. Detecting abnormalities in the dump truck and performing maintenance, inspection and parts replacement according to the machinery's condition reduces downtime.
