摘要：
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.
