Abstract
A system for automated dynamic compaction includes a compaction crane having a boom and compaction weight, at least one positional sensor, at least one boom deflection sensor, a rotational encoder, and a compaction control system. The compaction control system may be programmed to identify a first drop location having a first target parameter, determine whether the compaction crane is positioned over the first drop location, determine an initial elevation of the compaction weight, lift the compaction weight to a drop height, detect that the compaction weight has been released, re-hoist the compaction weight to the drop height, measure the payout length of a winch cable after each drop, determine a current elevation of the compaction weight after each drop, and determine whether the first target parameter has been satisfied.
