    • A straight traveling hydraulic circuit is provided. In case of performing a combined operation in which a fine operation of a working device and a fine traveling of a traveling device are simultaneously required, the straight traveling hydraulic circuit can allow the working device and the traveling device to operate independently, and thus prevent a declination or sudden traveling of the equipment. In case of performing the combined operation by simultaneously operating the traveling device and the working device, first and second center bypass shifting valves installed on the lowermost stream side of first and second center bypass passages are shifted by a pilot signal pressure that shifts a straight traveling valve installed on an upper stream side of the second center bypass passage, so that the degree of opening of the first and second center bypass passages is reduced to operate the working device and the traveling device independently.
    • 提供直行式液压回路。 在执行同时需要工作装置的精细操作和行进装置的精细行进的组合操作的情况下,直行运行液压回路可以允许工作装置和行驶装置独立地操作,从而防止 设备的倾斜或突然旅行。 在通过同时操作行驶装置和作业装置进行组合操作的情况下,安装在第一和第二中心旁通通道的最下游侧的第一和第二中心旁路换档阀被转移直线行驶 阀安装在第二中心旁通通道的上游侧,使得第一和第二中心旁通通道的开度减小,以独立地操作工作装置和行进装置。
