The standard hand guide for APH plates is isolated to minimise hand-arm vibration. Levels lower than 2.5 m/s² (excluding APH 100-20) enable operators to work longer shifts with the best comfort. The vibration levels are so low that safety codes do not require documentation of operator hours.
Ammann Orbitrol steering controls the adjustment of the centrifugal weights, allowing a smooth and easy change of direction while ensuring great accuracy on the jobsite. Machine speed and direction can be adjusted by a simple turn of the steering control lever. The machine also can hover and provide on-the-spot compaction for the more challenging areas. This system also helps improve productivity in corners and other tight spots.
A fully hydrostatic drive system eliminates the need for a V belt and a centrifugal clutch – and the maintenance that go with them. A hydraulic motor drives the eccentric shafts.
APH Hydrostatic Vibratory Plates can be equipped with the industry-proven Ammann Compaction Expert (ACE), an automated compaction measurement and control system. The ACE system on the vibratory plates utilises the same technology that has been used on Ammann’s heavy compaction machines for years. It provides operators with an accurate indication of soil stiffness and whether desired compaction has been achieved.
