Alternative Drive System for Excavators from Wacker Neuson: Full Power Output, Zero Emissions

Print Print this Article | Send to Colleague

Compact construction machines are characterized by a great deal of flexibility and versatile application areas. The smallest excavator 803 by Wacker Neuson is once again significantly expanding its application range with the dual power option. In combination with the electro-hydraulic generator HPU8, it is made into an emission-free helper with a few easy steps. With the dual power option, the Wacker Neuson excavator 803 can – in addition to the standard diesel engine – be connected to the external electro-hydraulic drive unit HPU8. Due to the generator, the excavator is operated electrically and completely emission-free. Contractors owning the 803 dual power have a machine that offers the features of a conventional diesel excavator, but at the same time, if necessary, also replaces special equipment for emission-free applications. This saves costs, ensures a higher machine utilization and expands the application areas of the mini-excavator.

Simple handling is particularly relevant for end users. If, for example, the excavator 803 is required for demolition / renovation work or interior restorations, the operator drives it in conventional mode to the site of operation. Two openings are embedded in the excavator's dozer blade in which the HPU8 can be suspended for transport. In this way, the operator brings along the generator via this transport support. The dimensions of the excavator 803 and the unit HPU8 are matched to each other so that the end user can easily drive through narrow door openings with the set. Once arrived on site, the operator simply connects the external unit to the excavator's undercarriage and can then continue to work completely free of emissions. 

The excavator is supplied with hydraulic power via the undercarriage. In this way, the tail swing radius and possibility of a 360-degree rotation also remain unrestricted in electrical operation – which means complete freedom of movement for the operator. The operating weight, stability and dimensions of the excavator do not change with the option and the output also remains constant in operation with the generator. For the operator, the sequence of operations thus remain completely unchanged after the connection of the generator.

The HPU8 unit designed specifically for excavator operation is characterized by its compact and sturdy design and the cooling capacity specially tailored for the compact excavator 803. The electro-hydraulic unit saves space, is easy to transport and is designed for work under full load at up to 45 degrees Celsius ambient temperature as well as at low temperatures. 

The excavator 803 dual power and the generator HPU8 are also of interest for rental yard operators: A high machine utilization is ensured due to the versatile application possibilities – indoors and outdoors. The generator is connected to the excavator's undercarriage via Plug & Play and is also no problem for less experienced operators. With a weight of 190 kg and compact dimensions, the unit can be stored and transported easily. The HPU8 is also very maintenance friendly: The simple design and easy-to-remove casing parts provide for good maintenance access. 

Perfectly equipped for a sustainable future
Wacker Neuson distinguishes particularly economical and environmentally friendly products with the ECO seal. ECO stands for ECOlogy and ECOnomy. The electro-hydraulic generator HPU8 and the excavator 803 dual power are among these products, because they give off zero emissions in the electric drive system mode and thus protect the environment. They are particularly economical thanks to the versatile application possibilities and the easy handling.
