The iBEX

First fully electric
powered dumper

4QT has developed the 4QT Paris Hybrid™ drivetrain, which equipment manufacturers can offer to end customers.


For the first prototype, the 4QT full-electric drivetrain was fitted into a RACO 2500 HSK Allraddumper supplied by Walo Bertschinger AG. 


The custom-built battery module has a capacity of 15 kWh and a nominal voltage output of 375 V. The electric motor is a 90kW synchronous machine.

The fully electrified RACO, or iBEX, is developed to TRL 6 and can reach speeds up to 30 km/h.

It is as such capable of emulating its conventional counterpart, as seen in the video.
