Wacker Neuson has a long tradition in the compaction industry. In 1930, Hermann Wacker invented the first vibratory rammer. At that time, this was a real innovation. Today, we continue to make new paths with our battery-powered vibratory rammers. Whether battery-powered or gasoline-powered with 2-stroke or 4-stroke engines, our vibratory rammers are designed for high performance and long life with high stroke energy, high percussion rate and long shoe stroke.
