vrijdag 12 februari 2010
Jan De Nul Group in Belgium has unveiled what it claims is "the next step in the development of hydraulic excavators that can be used in shallow to medium-deep coastal waters."
The development programme has been through a number of iterations and has resulted in a remote controlled excavator capable operating at depths of up to 30m. The basic excavator itself weighs 150 tons. This week the first underwater tests were executed in the Kluizendok.
The development of the remote controlled excavator saw Jan De Nul’s survey department and workshp work together on the the sonar system, the integrated GPS and the micro-digger to perform works under water with an accuracy of about 10cm.
The excavator has a 6m³ bucket and maximum digging depth of 10.4m. It has a digging force of 550kN. Additional equipment include a hydraulic hammer and scissor function.
