How does pallet shuttles work?

Conveyor line is placed in front of racking system for picking and receiving of pallets. Elevator will transport radio shuttle and pallets from ground to different layers. With instruction of WMS/WCS system, radio shuttle is able to automatically pick and deliver pallets to appointed position inside racks, which could realize automatic storage and retrieval of goods in warehouse.

The pallet what used for the four-way shuttle system, must be passed by speedlog test, As shown below:

Applications of pallet shuttle system

The pallet shuttle can carry hundreds of kilograms to one ton of pallet goods. The pallet four-way shuttle is an improvement in the structure of the two-way shuttle. The pallet two-way shuttle can realize "first-in, first-out" when picking up goods. Or the "first in, last out" model, which is mostly used in industries with large quantities and few varieties. However, with the continuous development of the market, the demand for small batches and multiple batches is increasing. At the same time, affected by factors such as land use and labor costs, enterprises have an increasingly urgent need for space utilization and dense storage. In this context, the four-way pallet shuttle that can realize intensive storage, space utilization and flexible scheduling came into being. At present, the pallet 4 way shuttle system has applications in manufacturing, cold chain and other industries. In addition, for old industrial parks and warehouses with few varieties and large quantities of goods, the pallet four-way shuttle system can also be considered to make full use of the height space of the warehouse, release more economic production capacity, and create value for customers. The specific applications are as follows:

1. A company with fewer items and more pallets.

2. Companies with high levels of loading and unloading activities.

3. Cold storage: It is very suitable for warehouses that need low temperature because it makes full use of storage space and reduces operation time. The system is more efficient when a stacker or transfer vehicle is used to install the automation system.

4. Buffer for temporary storage or order picking.

5. Seasonal product warehouse, inflow and outflow depend on the season, goods accumulate over a period of time until a large release at a specific moment, such as ice cream or toys.

6. Warehouses that need to access more items, store more pallets in depth, or increase the number of in and out movements to increase their productivity.
