Abstract: A concrete flow leakage-preventing shut-off valve includes an outer flexible casing configured to be disposed around a concrete delivery hose. A flexible inflatable bladder is disposed within the casing and defines a gas chamber therein. A gas intake/exhaust device extends through the casing and into the gas chamber such that pressurized gas introduced and exhausted from the gas chamber enables movement of the bladder to define closed and open concrete flow conditions of concrete relative to an outlet end of the hose. A clamping arrangement secures opposite ends of the casing and the bladder in radially and axially spaced apart relationship, and is configured to maintain a surrounding relationship of the casing and bladder with respect to the hose.

Abstract: An assembly for forming a mechanical interface for fastening tubular components includes a tubular pipe having at least one end with an external surface provided with groove structure. A tubular attachment is provided with a first engagement structure configured to be aligned with the groove structure on the tubular pipe. The tubular attachment is axially force fit on the outer end of the tubular pipe, and radially fastened thereto in response to at least one tool applied to the external surface of the tubular attachment. Also disclosed is a method for forming the mechanical interface between the tubular pipe and the tubular attachment.

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: 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.

Abstract: 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.
