for sheet piling work
When installing sheet piles unwelcome collisions with boulders, rocks or foundation remains can occur. This causes damage to the sheet piles, as well as the vibrator or basic machine. Obstacle recognition comes to the rescue.
The vibrator recognises obstacles before the sheet pile walls collide with them.
A signal appears on the control monitor to warn the operator should the amplitude measurement discover a harder object.
The amplitude measurement of Liebherr’s own high frequency vibrator records both its own frequency, as well as the reflecting negative amplitude. Therefore, the control system can recognize any obstacles under ground level before the sheet pile wall collides with them.
The operator is warned via the basic machine’s control monitor about any obstacles or inadmissible ranges of the vibrator.
