Retrofit for Hakkers with the Doosan to fully electric with 833 kWh 

Retrofit for Hakkers with the Doosan to fully electric with 833 kWh 

Following the successful electrification of the Klemm 807 (hybrid) and the fully electric conversion of the Sennebogen 650, SDK Engineering has started a third project for Hakkers: the electrification of a Doosan machine.

This machine will be converted to a fully electric drivetrain and equipped with an impressive 833 kWh battery system, enabling completely emission-free operation on site.

We are currently in the design and engineering phase. During this stage, we establish the technical foundation for a reliable and future-proof implementation.

Engineering focus areas

• Integration of the 833 kWh battery system

• Optimization of energy management and charging infrastructure

• Thermal management and safety systems

• Mechanical reconfiguration of the existing platform

• Smart software integration for maximum operational availability

By combining mechanical, electrical and software engineering, we deliver not just a zero-emission machine, but a practical and economically viable solution.

We sincerely appreciate Hakkers’ continued trust in SDK Engineering. The coming months will focus on further detailing and realization.

To be continued.
