Wacker Neuson: New Rammers are Emission-Free

MUNICH/GERMANY, April 30, 2015 - Wacker Neuson is taking a step towards the future with its new battery-powered rammer. Work is thus free of emissions and free of power cables.

The new battery-powered rammers are available in two versions: The smaller model AS 30 is a special rammer for the compaction of 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 the compaction process. Due to the zero emissions, both models easily stand up to strict requirements, such as on urban construction sites.

"The battery-powered rammer is a real novelty on the market. And it is the result of close collaboration with our customers, because we have implemented some requirements here that companies and users have brought to us," said Alexander Greschner, managing director of Wacker Neuson’s production. "For example, the battery-powered rammer 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."

20-30min operational time

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 percent in energy costs can be saved by operation with electricity. Of course, this depends on the local electricity prices. 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, Wacker points out the easy starting of a the machine at the push of a button. Batteries and battery chargers are designed so that they can be used independently of the model. The running time of the rammers is up to 20 minutes for the larger model AS 50 and up to 30 minutes for the rammer AS 30; with a quick charger, the battery is fully charged within one hour. For working 24/7, one thus needs three batteries and two chargers.

Rough batteries for construction site application

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 percent of the battery capacity is still available, says Wacker. Another benefit is the high temperature stability for operating temperatures between -10 and +50 degrees Celsius 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.
