Harbour reclamation

German contractor Detlef Hegemann uses Prolec’s pcX-3D system on its Liebherr 984 excavator during a large scale salvage operation in Barcelona.

The operation involved removing sediment and material from within tubes, each measuring 3.5 meters in diameter and around 17 meters in length, which were housed in submerged concrete segments. For this task, the contractor, Detlef Hegemann, used a Liebherr 984 excavator equipped with a special DOP pump, which was operated from a pontoon barge.

Being submerged, the tubes were difficult to locate and the subsequent task of positioning the DOP pump within the
tube without damaging the concrete segments was extremely difficult and time consuming. External guidance
could make the job simpler and more efficient.

Installing pcX-3D solved this particular problem by giving the operator a 3D view of each tube relative to the tool
position. This enabled the operator to accurately position the pump inside the tube and extract the material without
damaging the machine, the concrete segments or the tubes.

The system was installed using high quality marine grade AS8 and AS9 sensors, and the software was customised to
include a DOP tool attachment. A DTM of the job site showing each concrete tube location was loaded into pcX-3D.
