Sumitomo Heavy Industries Material Handling Systems Co., Ltd. and Yorigami Maritime Construction Co., Ltd. have developed design of a hybrid grab dredger that features Energy Fuel saving and Fully-Automatic Operation Systems. Their product recently received the 2014 Infrastructure Technology Development Award.
The Infrastructure Technology Development Award is nominated jointly by the Japan Institute of Country-Ology and Engineering and the Coastal Development Institute of Technology.
“ We have renovated existing floating crane with heavy lifting and piling function, and added bucket dredging function. For this renovation, we have applied our own Hybrid Energy Saving Technology and Fully-Automatic Operation system based on GPS signal ,” stated Sumitomo Heavy Industries.
Advantages of these two features are as follows:
1. Environmentally Friendly
Hybrid System enables to apply low fuel consuming smaller Engine Generator System and Energy saving. Fully-Automatic Operation system enables to achieve accurate operation and minimize the environmental damage of water pollution by dredging work;
2. Superior Operational Reliability
Dredging work requires the accurate and high speed motion with constant basis. Fully-Automatic Operation System also applied Electrical Inverter Control, Horizontal Digging Function, and Anti-Sway System and achieved more accurate and more effective operation.
