Abstract
A pipe shuttle for moving a pipe segment from an operating position to a pipe box. The pipe shuttle has a pair of gripper arms flanking a cradle. The cradle has a spring-loaded pad that has a concave surface for holding a pipe segment. As the pipe shuttle moves from underneath a pipe box to near a cradle, rollers are positioned to engage a guide plate. When the shuttle is underneath the pipe box, the rollers engage the guide plate to keep the cradle open. When moved towards an operating position, the rollers no longer engage the guide plate and cause grippers to close on the pipe segment. The spring-loaded pad allows the pipe shuttle to be moved relative to the pipe segment when the pipe segment is in its operating position.
