803 Dual Power

Tracked Conventional Tail Excavator

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.

  • Easy handling: Excavator weight, dimensions and machine center of gravity are unchanged


Easy to transport

Two openings are inset in the dozer blade in which the HPU8 can be suspended for transport.

Easy loading:

a sturdy lifting point for crane loading is attached on the connection lance.


Compact & practical

The loading dimensions of 930 x 720 x 1,000 mm are ideal. And four sturdy tie-down lugs ensure rapid transport.

Sophisticated design:

Simple Plug & Play connection on the undercarriage. The lifting point bracket is used as a connection lance and guide for the hydraulic hoses of the HPU8 at the same time. With a few hand movements, it is removed from the generator and connected to the excavator. The positioning on the undercarriage means 360° freedom of movement with the excavator.
