Welcome back to the our channel for a feature about the movement of gigantic aircraft and ships using pushback trucks on land and tug boats on sea for maneuverability. Pushback tugs are mostly used to push an aircraft away from the gate when it is ready to leave. These tugs are very powerful and because of the large engines, are sometimes referred to as an engine with wheels. Pushback tugs can also be used to pull aircraft in various situations, such as to a hangar. Different size tugs are required for different size aircraft. Some tugs use a tow-bar as a connection between the tug and the aircraft, while other tugs lift the nose gear off the ground to make it easier to tow or push. Recently there has been a push for towbarless tractors as larger airplanes are designed. Airlines should just hire bodybuilders to move them, it would be a green solution.
