摘要： The invention relates to a striking device (5) comprising a striking mechanism (8) which is driven by a pressure medium. Said device comprises a percussion piston (13) which can be displaced back and forth by means of a control device and a control valve which is embodied as a pressure shut-off valve (19) or as a stop valve, said control valve automatically stopping the striking mechanism if it exceeds a predetermined maximum value based on the working pressure controlling the inlet line, blocking the pressure line (3) or maintaining the control device in one of the and positions thereof. The inventive striking device also comprises a hydraulic catcher buffer which is used to brake the percussion piston when it exceeds a predetermined impact plane. According to the invention, the control valve must remain deactivated at least as long as the percussion piston is displaced on the hydraulic catcher buffer.

摘要： The present invention relates to a hydraulic attachment comprising a hydraulic circuit, the attachment being a construction or demolition tool, in particular a hydraulic breaker, demolition shears, scrap shears, a pulverizer, a gripper, a crusher bucket or a compactor, which can be mechanically connected to a support device and hydraulically connected to the hydraulic system of the support device. In order to enable the hydraulic circuit to be opened quickly and safely within an attachment and, in particular, to make it possible to display the presence of a particular pressure level within a hydraulic attachment and to determine whether a dangerous residual pressure is present in the system, a hydraulic attachment is proposed that has a residual pressure display (40) which is connected to the hydraulic circuit of the attachment in a detachable or non-detachable manner.

摘要： Depending on the working and application conditions, it may be desirable to equip fluid-operated percussion devices with a mechanism that protects against no-load strokes, particularly in the interest of avoiding undesired stress. In the present case, this protection mechanism is configured such that the control unit that influences the movements of the percussion piston is blocked by a safety element in the form of a multiple-position valve, and the percussion device is halted if the percussion piston overshoots the extended position occurring in normal operation by a defined distance, thereby assuming a no-load-stroke position. The safety element (21) that acts on the control unit (5) of the percussion device (1) is automatically controlled, notably such that it is not switched to be active until some time after the startup of the percussion device (1) acted on by the working pressure. The percussion device (1) can therefore start up without being influenced by the safety element (21).
摘要翻译：根据工作和应用条件，可能需要为流体操作的冲击装置提供一种防止空载冲程的机构，特别是为了避免不期望的应力。在这种情况下，该保护机构被构造成使得影响冲击活塞的运动的控制单元被多位阀的形式的安全元件阻挡，并且如果冲击活塞过冲则敲击装置停止延伸位置在正常操作中发生定义的距离，由此假定空载行程位置。作用在冲击装置（1）的控制单元（5）上的安全元件（21）被自动控制，特别是在冲击装置（1）起动之后的一段时间内不被切换为有效在工作压力下。因此，冲击装置（1）可以在不受安全元件（21）影响的情况下启动。

摘要： A demolition claw has a support, a pivot pin mounted on the support and centered on and extending along an axis, and two jaws each having a hole through which the pivot pin extends so that the jaws can pivot on the support about the axis. The jaws have adjacent the respective holes confronting flat faces. An arcuate formation fixed on one of the faces adjacent the respective hole projects axially therefrom toward the other of the faces and is generally centered on the axis. A retaining formation fixed on the other of the faces adjacent the respective hole projects axially therefrom toward the one face, is radially offset from the arcuate formation, axially overlaps the arcuate formation, and surrounds the arcuate formation. Structure is provided on one of the jaws for preventing axial separation of the jaws.
