摘要： There are provided a excavator body, a cabin provided on the upper surface, a work attachment mounted on the front part of said excavator body, and railings and roof supports forward of the cabin and rearward of a boom constituting the work attachment, the boom being arranged not to interfere with the roof supports in the whole rising and falling operating range over the whole swing operating range. Thereby, the maximum stand-up angle of he boom is enlarged to a specification angle, and the minimum rotating radius of the upper construction body including the work attachment is reduced to secure necessary railing function, enabling installation of a roof naturally in a minimum space.
摘要翻译：设置有挖掘机主体，设置在上表面上的机舱，安装在所述挖掘机主体的前部的工件附件，以及在所述机舱前方的栏杆和车顶支撑件以及构成所述作业附件的起重臂的后方，所述起重臂为安排在整个摆动运行范围内，不影响整个上下工作范围内的屋顶支撑。由此，将起重臂的最大起立角度扩大到规定角度，并且减小包括作业附件的上部结构体的最小旋转半径以确保必要的栏杆功能，从而能够在最小空间内自然地安装屋顶。
