摘要： A pile is moved downwards by a movable part inside a piling apparatus. An apparatus body is fastened to the pile by fastening elements, during piling the movable part inside the apparatus body is moved downwards, the movable part is stopped hydraulically by medium in a cylinder space without the movable part striking the apparatus body. As the downwards directed motion of the movable part is stopped, the apparatus body and the pile fastened to it jerk downwards, after which, the movable part is moved hydraulically upwards. The counterforce of the motion affects the apparatus body and the pile fastened to it by pushing them downwards. The piling apparatus includes hydraulic cylinder cylinder to the piston of which the movable part is fastened, and to the hydraulic cylinder are connected a pressure transformer, a damping apparatus and a set of control valves to stop the movable part hydraulically.

摘要翻译： 堆垛机内的活动部件向下移动一堆。 装置主体通过紧固件紧固到桩上，在打桩期间，可移动部件在装置主体内部向下移动时，可移动部件被媒体液压地停留在气缸空间中，而不会使可移动部件撞击装置主体。 随着可动部件向下的定向运动停止，装置主体和紧固在其上的桩向下冲动，此后可移动部件向上液压移动。 运动的反作用力通过向下推动装置主体和固定在其上的桩来影响。 打桩装置包括液压缸缸体，活塞部件被紧固在活塞上，液压缸连接有压力变压器，阻尼装置和一组控制阀，以液压地停止可动部件。
