AMMANN TRIPLE SHAFT
EXCITER UNIT
MARKET LEADING TRIPLE SHAFT EXCITER SYSTEM GIVES AMMANN APH VIBRATORY
PLATES THE EXTRA EDGE WHEN CONDITIONS GET TOUGH
Ammann remains the technological leader in plate compaction with its patented triple-shaft exciter system.
The system keeps plate movement consistent, which in turn enables smooth travel – even through heavy, cohesive soils – and
helps effortlessly overcome steep grades. APH machines are impressive climbers and can even do so while backfilling saturated
areas – work that can leave competitive products at a standstill.
The success of the plates starts with the use of the third shaft. With twin-shaft systems, plates can rock back and forth and
their leading edge can turn downward and become stuck, particularly in saturated materials.
With the Ammann exciter system, the third shaft prevents that back-and-forth movement by providing another force. This
creates more consistent drive of the plates and keeps them even, steady and above the surface – even on saturated jobsites.
