Abstract: A locking arrangement (40) for a pipe coupling takes the form of a spring biased pin (58) captively and moveably mounted in a through opening formed either in an overlapping member (29') of one of the coupling sections or the handle (30') for movement into and out of an alignable opening formed on either the handle (30') or on the one overlapping member (29') of the one coupling section. The pipe coupling includes an assymetrically shaped gasket (65) for permitting coupling of a metric end boom elbow or pipe with a heavy-duty end boom hose or pipe.

Abstract: A method and system for monitoring replaceable components of a work unit is disclosed. The method assigns an RFID tag to each wear part of a work unit. Prior to each operating cycle, the RFID tags are read and the RFID tags are correlated to corresponding wear parts. During operation of the work unit, operating parameters are read from the pumping unit and associated with each of the wear parts. A real-time life cycle status is determined for each of the wear parts based upon historic operating parameters and present operating parameters. Based upon the real-time life cycle status, the system and method of the present disclosure predicts the remaining wear life and relays this information to interested third parties. Interested third parties can then contact the equipment owner to provide information as to when parts need to be replaced prior to failure.

Abstract translation: 公开了用于监视工作单元的可更换部件的方法和系统。 该方法为工作单元的每个磨损部分分配RFID标签。 在每个操作循环之前，RFID标签被读取并且RFID标签与相应的磨损部件相关联。 在工作单元的操作期间，从泵单元读取操作参数并且与每个磨损部件关联。 基于历史操作参数和当前操作参数为每个磨损部件确定实时生命周期状态。 基于实时生命周期状态，本公开的系统和方法预测剩余磨损寿命并将该信息传递给感兴趣的第三方。 然后有兴趣的第三方可以联系设备所有者提供有关部件何时需要在故障之前进行更换的信息。

Abstract: A concrete boom hose is provided with a first end that is connected to the outermost end of a series of concrete pipes and a second end through which the flowing concrete exits. The second end is provided with an inner diameter that is smaller than the inner diameter of the first end that is connected to the concrete pipe.
