Abstract
A lot of work machines based on hydraulic excavators were developed for various complex work fields like dismantlement, industrial waste disposal, etc. And such kinds of work machines also play important parts in disaster recovery such as earthquakes, typhoon, and flood. We think that an adaptation to more complex works will be requested in the future. To achieve more complex handling work function, we developed a new type of work machine called "ASTACO". ASTACO features at including two fronts and is based on 7-ton class hydraulic excavator. A new operation system can let the operator to handle the two fronts with his two hands freely and intuitively at the same time. In this paper we report summery and key function of ASTACO.
