LKV, a German company with expertise in specialist groundswork, have reported how the Ammann add on plate compactor ACA2030 cut their work time in half.
This was during a recent job, where hundreds of pylons were installed for drainage channel construction.
The embankment required installation of 3-4 wooden pylons per metre for distance of up to 500 metres. The posts ultimately providing stabilasation for the drainage channels.
The compactor was productive because of it's vertical downward striking impact. Powered by its 2-shaft technology and directional oscillator, the pylons were held in an upright position and simply compacted until they reached the required depth.
Johann Pfluger of LKV told us "This type of work previously required pre-drilling of the holes and then pushing in the pylon with an excavator. Using the ACA2030 this took less than a minute per pylon, it took twice as long before."
The cost-savings was considerable, as were safety gains. “Some of the pylons could not be fully inserted with the previous method,” Pflüger said. “They had to be cut to size by hand using a chainsaw. With this compactor, the pylon went as far as it needed.”
