  • Apparatus and method of detecting defects in a rail joint bar
    Patent number: 8806948
    Abstract: An inspection apparatus for detecting defects in a rail joint bar includes an ultrasonic transducer mounted on an actuator for moving the transducer into and out of engagement with a vertical surface of the head of the joint bar. A laser profile system and an encoder output linear position data corresponding to the position of a joint bar relative to the position of the inspection apparatus. A system controller responsive to the identification of the presence of a joint bar or obstructions, outputs control information to the transducer actuator assembly to position the transducer assembly relative to the joint bar.
