The measurement carriage 40 is configured to run on a track comprising a pair of c-beams, for example an overhead production line conveyor. The carriage comprises a main body 42 and at least one running wheel 44 to run on an interior surface of the c-beams. At least one running wheel is a measurement wheel 48 moveably mounted to the main body. A moveable mount 62 biases the measurement wheel away from the interior surface of the c-beam with respect to the main body such that its movement on the moveable mount follows variation in distance between the opposed interior surfaces as the carriage moves along the track. The carriage further comprises a strain or load sensor to monitor movement of the measurement wheel on the biased moveable mount, and to output a signal indicative of distance between the respective opposed interior surfaces. The carriage may be coupled to laser apparatus comprising a laser emitter and receiver. The laser emitter scans a separation between the C-beams and the laser receiver senses laser light reflected from the C-beams, and outputs a signal indicative of the separation measured. The invention inspects wear of c-beam tracks due to erosion or excessive forces.
