Green light for shipping traffic
Over the years the depth of the water at the mouth of the port was reduced to as little as 8 m through sediment. Not only was sediment removed but also the depth of the water was increased to 14 m in order to allow for larger vessels to run into the port.
Great tasks require great machines
Material amounting to a total of 600,000 m3 had to be removed from the entrance to the port. On the one hand, the challenge lay in achieving high levels of turnover and, on the other hand, in removing not only sediment but also larger stones. With the duty cycle crawler crane type HS 8300 HD, the contractor Zeta S.r.l. found a real powerhouse and a suitable solution for this dredging project.
The work in Piombino was carried out in a six-month project by the Italian dredging specialist Zeta S.r.l.
Hybrid duty cycle crawler crane with low consumption
The duty cycle crawler crane is equipped with a hybrid drive system. Through the storage and subsequent reactivation of surplus energy the turnover can be increased and, at the same time, the fuel consumption can be significantly reduced. Despite high levels of turnover the duty cycle crawler crane has up to 50 % lower diesel consumption (60 l/h) in comparison to similar models.
The work in the Port of Piombino clearly confirmed that the HS 8300 HD is a machine for heavy duty material handling.
Liebherr was distinguished with “HIGHLY COMMENDED” at the “Dredging and Port Construction Innovation Awards” in London. This recognition of our work is a clear positioning for Liebherr in the dredging sector.
