Four-way Shuttle Car and multi-layer shuttle car? Let’s learn about it together below.
1. Four-way truck shelves are a type of automated storage shelves. It uses the vertical and horizontal movement of four-way trucks, and combines the rotation of elevator to achieve the purpose of warehousing automation. A four-way vehicle, also known as a four-way shuttle vehicle, can move horizontally and vertically along a predetermined track load to realize the storage and retrieval of goods to the shelf's cargo space. This device can realize automatic storage and retrieval, automatic lane change and layer change, and automatic hill climbing. It can also be carried and driven on the ground. It is the latest generation of intelligent handling equipment integrating automatic stacking, automatic handling, and unmanned guidance. The four-way shuttle car has high flexibility. It can change the working lane at will and adjust the system capabilities by increasing or decreasing the number of shuttle cars. If necessary, the scheduling method of forming a working fleet can be used to respond to the peak of the system and solve the bottlenecks of entry and exit operations.
Two- and four-way shuttle cars can be replaced by each other. When a shuttle car or elevator fails, other shuttle cars or elevators can be dispatched through the scheduling system to continue to complete the operation, and the system capabilities will not be affected. In terms of overall system cost, the four-way shuttle system is also very advantageous. Since the cost of ordinary multi-layer shuttle trucks or stacker systems is closely related to the number of tunnels, when the order volume is increased and the inventory volume is not increased, the corresponding cost will be increased for each tunnel of these systems. The four-way shuttle truck system only needs to increase the number of shuttle trucks, and the overall cost is lower.
Three- and four-way shuttle vehicles are suitable for low-flow and high-density storage, as well as high-flow and high-density storage. It can maximize efficiency, cost and resources.
4. The cost of a multi-layer shuttle vehicle or stacker system is closely related to the number of tunnels. When the order volume is increased and the inventory volume is not increased, the corresponding cost will be increased for each tunnel of these systems. The four-way shuttle vehicle system only needs to increase the number of shuttle vehicles, and the overall cost is lower.
5. The two should be compared from the entire system to make sense. The main equipment that constitutes the shuttle truck storage system includes shuttle truck, shelves, hoists, front-end conveyor , software system and other aspects. Generally speaking, the single-machine price of a four-way shuttle car is higher than that of a multi-layer shuttle car, but the utilization rate of a four-way shuttle car is high, the actual number of required, and the number of supporting elevators is also small; in terms of shelves, the two are roughly the same, and the shelves of a four-way shuttle car are slightly more expensive; the multi-layer shuttle car in front of the warehouse is more complicated; the software four-way shuttle car is much more complicated. The difference between the two must be determined based on the specific items.
