Previously the compacted cargo had to be removed from the rafters, stairs and platforms using brute forces and labourcosting man hours. Now the HPU attached to an excavator can be used to remove the compacted cargo in less time with less cost and less damage to the vessel.

The HPU uses 2 high-frequent vibrating pikes driven by the hydraulic system of the excavator. If you place the pikes on the ships hold it will move the high-frequent motion into the compacted cargo and subsequently loosen the compacted material.
In this way it won’t harm the ship, the excavator or the man operating the excavator.
