Hitachi Rigid Dump Trucks have been developed to efficiently transport resources excavated at large-scale mines around the world. Among these, the EH5000AC-3 boasts one of the largest loading capacities in Japan. Power generated with an engine-powered generator is controlled through a control cabinet using an IGBT inverter, while driving an alternating current wheel motor to achieve stable running through sophisticated vehicle control. Our trolley charging type rigid dump truck that switches its power source to overhead wire supply on uphill roads. This achieves around twice as fast than non- trolley charging type. By curbing maintenance costs and CO2 emissions through reduced engine load, Hitachi Rigid Dump Trucks help customers lower costs and reduce environmental impact at the same time. This is the culmination of the manufacturing technologies Hitachi Construction Machinery has cultivated over many years and the advanced technologies of the Hitachi Group that have been refined in the manufacturing of high-speed rail cars and development of social infrastructure. ※IGBT: Insulated Gate Bipolar Transistor. It is a semiconductor that controls and supplies electric power.
