The APU series is a technological milestone: As the first reversible vibratory plates worldwide, the battery-powered vibratory plates of the APU series are particularly efficient and completely maintenance-free as a result of the DireX direct drive. The emission-free drive and the low overall height make it the ideal compaction equipment for shoring in trenches. The APU series has excellent operational properties on soil and asphalt, and provides a high degree of operating comfort, for example through the sturdy, integrated wheel set and the continuously adjustable forward and reverse travel speeds.
