    • To secure a wide space in a cab while avoiding interference between a device provided on an upper slewing body and the cab. A cab 30 includes a floor plate 31 that constitutes a floor surface of the cab 30 and a frame-shaped lower frame 34 which extends along a peripheral edge of the floor plate 31 and which is fixed onto the floor plate 31. A swivel joint 50 is arranged below the floor plate 31 such that a part of the swivel joint 50 overlaps with a peripheral edge of the lower frame 34 in plan view. A floor-side projecting portion 31a that projects upward is provided on the peripheral edge of the floor plate 31 and a floor-side housing portion 31d that houses the swivel joint 50 is provided below the floor-side projecting portion 31a. A frame-side projecting portion 34a that projects upward is provided on the lower frame 34, and a frame-side housing portion 34d that houses the floor-side projecting portion 31a is provided below the frame-side projecting portion 34a.
    • 为了确保驾驶室较宽的空间,同时避免设置在上部回转体上的装置与驾驶室之间的干涉。 驾驶室30包括构成驾驶室30的底面的底板31和沿底板31的周缘延伸且固定在底板31上的框状的下框架34.旋转接头50 布置在底板31的下方,使得旋转接头50的一部分在平面图中与下框架34的周边边缘重叠。 在底板31的周缘设置有向上方突出的地板侧突出部31a,在地板侧突出部31a的下方设置有收纳旋转接头50的地板侧收纳部31d。 在下框架34上设置有向上方突出的框架侧突出部34a,在框架侧突出部34a的下方设置有收纳地板侧突出部31a的框架侧收纳部34d。

    • Provided is an upper slewing body (1) allowing elements to be compactly arranged while preventing required length of a hydraulic pipe from increase. The upper slewing body (1) includes an upper frame (10), an engine (31), a hydraulic pump (33) coupled thereto, a control valve (60) forward of the engine and rearward of a slewing axis, and a rear tank (50) between the engine (31) and the control valve (60). The control valve (60) is oblique to a frame lateral direction so as to locate a front end portion (65) thereof forward of an inner end portion (67) thereof. The rear tank (50) has a rear opposition side surface (53) opposed to a rear side surface (63R) of the control valve (60) while being oblique to the rear side surface thereto.
    • 提供了一种允许元件紧凑布置的上部回转体(1),同时防止液压管的所需长度增加。 上回转体(1)包括上框架(10),发动机(31),与其联接的液压泵(33),发动机前方和后回转轴线的控制阀(60) 发动机(31)和控制阀(60)之间的油箱(50)。 控制阀60相对于框架横向倾斜,以使其前端部(65)位于其内端部(67)的前方。 后箱(50)具有与控制阀(60)的后侧面(63R)相对的后方侧面(53),同时向后侧面倾斜。
