    • An antivibration mounting apparatus (30) is provided with a case (31) fixed to a turning table (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 relative displacement of the stud (33) to the case (31) in the diameter direction is suppressed by the elastic body (34). On the lower part of the case (31), an attenuating mechanism (40) having an attenuating liquid (43) stored in a liquid chamber (42) and an attenuating member (41) fixed by the stud (33) is provided. Furthermore, on the upper part of the case (31), an air spring (50) supported by the stud (33) or the case (31) is provided, and a load transmitted from the cab (20) to the stud (33) in the shaft direction is supported by the air spring (50).
    • 防振安装装置(30)设置有固定到转台(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,并且通过弹性体(34)抑制螺柱(33)与壳体(31)在直径方向上的相对位移。 在壳体(31)的下部设置有具有存储在液体室(42)中的衰减液体(43)和由螺柱(33)固定的衰减构件(41)的衰减机构(40)。 此外,在壳体31的上部,设置有由螺柱(33)或壳体(31)支撑的空气弹簧(50),并且从驾驶室(20)传递到螺栓(33)的负载 )在轴向上由空气弹簧(50)支撑。
