摘要:
A shut off valve for use with a concrete delivery hose includes a pair of flexible cylindrical sleeves disposed within a rigid casing that surrounds the hose. A gas chamber is defined between the sleeves so that when pressurized gas is forced into the chamber the inner sleeve will be displaced radially inwardly to constrict the hose and stop the flow of concrete.

A modular system for adapting a boom concrete system into a line concrete pumping system utilizes a first substantially 90 degree elbow connected to the pump outlet so that the concrete flow is directed downwardly from the outlet. A second substantially 90 degree elbow is pivotally attached to the first elbow so that the concrete flow direction can be selectively positioned in a horizontal plane. The second elbow further includes a reduced diameter at its outermost end.

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.

摘要:
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.

The inlet end of the boom hose (20) is coupled to the outer end of a concrete delivery pipe (18). The inner diameter of an outlet end, from which concrete flows, is made smaller than the inner diameter of the inlet end.
摘要:
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.
