Wacker Neuson dual power is the innovative solution for an emission-free auxiliary drive. In addition to the integrated diesel engine, the electro-hydraulic unit HPU8 can be connected to the 803 compact excavator if necessary. The HPU8 is technically tailor-made to the requirements of the excavator 803. In this way, the excavator can be operated electrically and emission-free if necessary. The handling is easy: The generator is connected to the undercarriage via Plug & Play – done.
Two drive options: Diesel and electro-hydraulic drive
Emission-free if necessary: For work indoors and in sensitive environments
Consistent performance with both drives – even in breaker operation.
Unrestricted work movements: Rotatable 360° with both drives
Easy handling: Excavator weight, dimensions and machine center of gravity are unchanged
