Compared with a reciprocating shuttle vehicle, the annular shuttle vehicle has the advantages of strong conveying capacity, high conveying efficiency and compact overall layout of the conveying line, and is more suitable for workshop production type automatic logistics systems.

Most of the existing annular shuttles are of two-wheel single-rail structures or four-wheel double-rail structures. The requirement of the annular shuttle of two-wheeled single track structure to the track is higher, and the track has the restriction to the size of automobile body, if the automobile body size is too big, easily takes place to turn on one's side during the turn. In addition, the running balance and stability of the annular shuttle vehicle with the two-wheeled single-rail structure are poor, and the annular shuttle vehicle shakes violently during bending. Annular shuttle of four-wheel double track structure, because the orbit radius when interior foreign steamer turns is different, the turning radius of outside wheel will be greater than the turning radius of inboard wheel, and the unable synchronous roll of interior foreign steamer during the event turns causes inside and outside walking wheel relative slip, and the wearing and tearing of aggravation wheelset reduce the mechanical life of wheelset. In addition, the structure easily causes extrusion and impact between the wheel set and the guide rail due to inertia when the structure is bent excessively, and vibration and noise are easily generated. To the shuttle that adopts the interior outer wheel interval of subassembly compensation that slides, its wheelset structure is more complicated, and manufacturing cost is higher, and the relative wheelset of frame will produce the slip when crossing the turn, and the stability and the security of the shuttle when carrying on the operation of heavy weight goods are relatively poor.
