A post a while back talked about nosewheel tugs that lift the whole nosewheel and move it around. That post can be seen here. I commented then about how large the tug was. I hadn’t then seen that there are far smaller versions of the same concept. This one is in operation at SeaTac. It is suitable for narrow body jets and regional jets. I don’t know whether it is being trialed or whether these will gradually replace the traditional tugs. I guess we shall see in due course.
