Technology
We help heavy equipment OEMs electrify their diesel fleets.
This allows their customers, construction contractors, to win more tenders, avoid environmental fines, and improve their unit cost.

The iBEX
First fully electric
LFP-battery
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.
