Method and machine for dynamic ground compaction |
摘要 |
At least one cable is attached to a load lying on the ground via a releasable connection mechanism. A traction force is applied to the cable to hoist the load up to a prescribed height. That traction force is then eliminated or reduced to initiate a downward movement of the load followed by the cable. The connection mechanism is then released while the load is moving downwardly.
