摘要：
A device is described for positioning a reinforcing cage within a cylindrical concrete pipe form. The device comprises a horizontally movable slide which may be moved inwardly into the form for engagement with the cage. A cam is secured to the slide for moving the slide inwardly and outwardly relative to the form. An air cylinder is pivotally connected to the cam for pivotally moving the cam. An adjustable stop is located in the pivotal path of the cam to limit the inward movement of the slide. A plurality of the devices are mounted on the form in a radially spaced and vertically spaced manner.
