Rail Guided Vehicle (RGV), also called Sorting Transfer Vehicle (STV) or Shuttle Loop System (SLS), is a complex automated unit load handing system. The system consisted of self-proplled, self-steering vehicles moving on circuit aluminum rail system, by setting up multiple pick-up and drop-up stations, manufacturing, storage and picking process can be performed efficiently and accurately. It can be used to move unit loads with various sizes, whether in boxes/containers or pallets, load range from 30kg to 3tons. Its aluminum rails can be in the form of loop or in a straight line. The transfer mechanism can be roller based or chain-based. Through vehicle-to-vehicle communication, the vehicles are maintained optimal distance from each other, preventing collisions and maximum inbound & outbound throughput. This RGV system from Huaruide is high dynamic system for transporting a huge range of different unit loads while achieving excellent throughput rates. It is here in particular that the interfaces to the adjoining warehouse and materials handling installations play a crucial role.
