Hybrid Grab Bucket Dredger is received the Infrastructure Technology Development Award
August 20, 2014
Sumitomo Heavy Industries Material Handling Systems Co., Ltd. (Head Office: Shinagawa, Tokyo; President and CEO: Katsuhide Yokota; a wholly-owned subsidiary of Sumitomo Heavy Industries, Ltd.; hereinafter referred as “the Company”) and Yorigami Maritime Construction Co., Ltd. (Head Office: Kobe, Hyogo Prefecture; President and CEO: Shigeyuki Yorigami) jointly developed the design of hybrid grab dredger which has Hybrid System for Energy Fuel saving and Fully-automatic Operation System. We hereby announced that this product was received the “Infrastructure Technology Development Award” of Year 2014.
The Infrastructure Technology Development Award is nominated jointly by the Japan Institute of Country-Ology and Engineering and the Coastal Development Institute of Technology. This award is to praise the Excellent New Technology of the Construction Field and its Innovators contributed to develop. There are three classifications for this Award as “Best” “Superior” “Award”, Award is lowest.
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. Advantages of this two Features are as follows:
1. Environmentally FriendlyHybrid 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 ReliabilityDredging 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. Accurate Operation by this Automatic Operation System also good for the operational safety because of the motion is stabilized.
