Similar carried by the carriage trains, TUG are used to transport one or more "cars", which in this case can be a variety of wheeled racks.

The main features of these AGVs are of locomotion systems with high traction and constraint radius of curvature of the path so that it is possible to transport trains.

Very popular in the automotive industry TUG are primarily utility transport Kits parts of the areas of sequencing or warehouse to the point of use on production lines.

Thus the application of AGVs tugs in the logistics supply production lines becomes much more efficient than conventional systems that use forklifts for the transport unit of the collections to the points of use.
