The advancements, which include Hitachi’s insulated gate bipolar transistor propulsion technology, will be introduced at the show.

The IGBT technology also propels Japan’s famous bullet trains.

It is said to outperform previous and competitive systems through its simplicity, improved efficiency and dependability.

The technology enhancements will be embodied in a rigid-frame hauler at Hitachi’s booth.

The truck features propulsion technology that delivers a higher level of efficiency, vastly improving machine operations.

Hitachi division manager Ryan Blades said Hitachi had a history of focusing on key areas of the mining process.

“By specialising only in shovels and haulers, Hitachi is able to focus without compromise on producing highly efficient and productive machinery,” he said.

“The new AC-drive technology advancements are a perfect example of the superior quality and performance of this approach.”

Besides the AC-drive technology, Hitachi will also provide updates on its excavator fleet.

Minexpo runs on September 24-26 at the Las Vegas Convention Centre, Las Vegas, Nevada.
