Dredging contractor Co.Ed.Mar from Chioggia (Italy) is using its self-propelled barge “Wise” to remove the sediment. It is equipped with a brand new Liebherr duty cycle crawler crane type HS 8130 HD with hydraulic clamshell bucket. Thanks to the optimum grab capacity of 6 m³, quicker movements and larger outreaches can be achieved during operation. Co.Ed.Mar attains cycle times of only 45 sec. when dredging material from the seabed and 25 sec. when unloading the vessel. This results in an average turnover of approx. 400 m³ per hour (equal to the barge loading capacity).
