    • A vibration-isolating mount device (30) has a case (31) fixed to a turntable (13) and a stud (33) fixed to a cab (20). An elastic body (34) is provided between the case (31) and the stud (33), and a relative radial-directional displacement of the stud (33) to the case (31) is suppressed by the elastic body (34). Further, a damping mechanism (40) having damping liquid (43) contained in a liquid chamber (42) and a damping member (41) fixed to the stud (33) is provided under the case (31). Furthermore, an air spring of which both ends are supported by the stud (33) or case (31) is provided above the case (31), and an axial-directional load transmitted from the cab (20) to the stud (33) is supported by the air spring (50).
    • 防振安装装置(30)具有固定到转台(13)的壳体(31)和固定到驾驶室(20)的螺柱(33)。 弹性体(34)设置在壳体(31)和螺栓(33)之间,弹性体(34)抑制螺柱(33)与壳体(31)的相对的径向位移。 此外,在壳体(31)的下方设置有包含在液体室(42)中的阻尼液(43)和固定在螺柱(33)上的阻尼部件)的阻尼机构(40)。 此外,在壳体31的上方设置有由螺柱33或壳体31支撑两端的空气弹簧,并且从驾驶室20传递到螺柱33的轴向载荷, 由空气弹簧(50)支撑。
