Wacker Neuson: Battery-powered rammer for emission-free work

Zero emissions and low operating costs characterize the battery-powered rammer.

Innovations in the field of compacting technology are a tradition at Wacker Neuson: a groundbreaking invention was therefore created with the first rammer in 1930 – and many innovations then followed. Wacker Neuson is now taking another step towards the future and with the new battery-powered rammer is offering customers the possibility to work completely emission-free, without a power cable. Wacker Neuson is therefore again demonstrating its innovative leadership in this segment.

The new battery-powered rammers are now available in two versions. The smaller model AS 30 is a special rammer for compacting pipe gussets. The battery-powered rammer AS 50 is used for all traditional rammer work. The batteries of both machines can be removed without tools so that the operator can exchange the discharged battery with a charged battery in a few simple steps. This concept makes the operator independent of cables during compaction. Because of the zero emissions, both models easily stand up to strict requirements, e.g. for urban construction areas or working in trenches.

"The battery-powered rammer is a real novelty on the market. It is the result of close collaboration with our customers, because we have implemented some requirements here that companies and end users have brought to us," says Alexander Greschner, managing director of Wacker Neuson Produktion GmbH & Co. KG. "For example, the battery-powered rammer with zero emissions can fully display its strengths in trench applications and when used in buildings. For emission-free work not only protects the health of the operator, but also expands the range of application of the rammer — and therefore the flexibility of the company."

55 per cent savings in energy costs
An additional advantage is the low operating costs, since there are no typical maintenance jobs of conventional rammers with the battery-powered rammer, for example maintenance work on the carburetor. This also applies for the energy costs: Around 55 per cent in energy costs can be saved by operation with electricity. These properties, zero emissions and particular economic efficiency during operation are also reasons why the battery-powered rammer has been awarded the ECO seal by Wacker Neuson – ECO for ECOlogy and ECOnomy. In addition, the easy starting at the push of a button speaks for the battery-powered rammer. Moreover, batteries and battery chargers are designed so that they can be used independently of the model. The AS 50 battery operated rammer has a running time of up to 20 minutes, and the AS 30 has a running time of up to 30 minutes. Thanks to the quick charger, the battery can be completely charged within one hour.

Wacker Neuson uses lithium iron phosphate batteries. Compared to the typical lithium cobalt oxide batteries, which are used in cell phones and laptops, these have some properties that prove to be very beneficial in the construction site environment. The long service life is particularly beneficial here: even after 1,500 charge cycles, at least 80 per cent of the battery capacity is still available. Another benefit is the high temperature stability for operating temperatures between -10°C and +50°C, as well as the specific safety concept that reliably rules out a spontaneous combustion or catching fire in the event of damage from the outside.

With the introduction of the new battery-powered rammer, Wacker Neuson offers an innovative and comprehensive product portfolio of rammers: from the 30–70 kilogram class and from the drive system with diesel, gasoline (2-cycle and 4-cycle) or an electric motor with battery operation. No other manufacturer offers more selection and expertise.
