Description

What is 4-way shuttle rack system?

4-way shuttle system is an automated storage racking system. Uses smart shuttles to move and arrange pallets. Able to move flexibly in four directions (forward, backward, left, right) allowing free lane changes. Using warehouse management software (WMS) helps shuttles move to any cargo location. Detect and actively avoid obstacles, suitable for many different pallet sizes. In the event of a problem, shuttles still operate through other elevators, ensuring that capacity is almost unaffected. Meets high-density storage requirements with high efficiency and flexibility.

Structure and operating principle

Working principle

The system operates based on the coordination between hardware and software:

Import goods: Goods are placed at the entry point, the elevator will bring the pallet to the correct shelf level for storage.

Storage: The shuttle receives orders from the management system. It will move into the racking bay to deliver the pallet to the designated storage location.

Product delivery: When requested, the shuttle will automatically move to the location of the pallet to be picked. It will take the pallet out and the elevator will transport it down to the delivery point.

The entire process is controlled by warehouse management software (WMS), ensuring the system operates smoothly and accurately.

Main structure

Shelving system: The specially designed shelf has internal guide rails, allowing the shuttle to move safely and accurately.

Automatic shuttle: The vehicle is capable of moving in 4 directions (forward, backward, left, right), and is primarily responsible for picking up and placing pallets.

Elevator: This equipment helps move shuttles and pallets up and down between rack levels.

Conveyor: Transport pallets from the point of entry to the racking area and vice versa. Conveyors help synchronize goods, reduce waiting time and increase processing productivity.

AGV: responsible for moving pallets between different areas in the warehouse. AGVs operate on pre-set routes or navigate intelligently based on real-time data from the management system.

Outstanding advantages of 4-way shuttle

4-way shuttle racking system makes full use of warehouse height and space. It can increase storage capacity up to 90%, saving warehouse expansion costs.

The system supports both FIFO and LIFO principles. It can meet diverse warehouse requirements.

Shuttle and elevator work together in perfect harmony. Equipped with a high-precision positioning system that uses QR codes and positioning points on the floor to identify the location.

The automatic operation process reduces risks. The Four Way Shuttle Robot can intelligently detect obstacles in front. When encountering obstacles, the device will automatically brake and send out a warning signal. Goods and staff are more safely protected.

Common applications of 4-way shuttle

Food and beverage industry

The industry is characterized by the need to store large quantities of homogeneous products with short life cycles. The system supports both FIFO and LIFO, suitable for many different types of products. Ability to control each pallet, quick retrieval, stable operation in low temperature conditions.

E-Commerce

With huge order volumes and the need for flexible real-time processing. Shorten picking and packing times, enabling faster delivery. Ability to manage large numbers of different product codes (SKUs) and handle flexibly during peak shopping periods.

Major logistics and distribution centers

These centers require continuous volume of goods and complex in-and-out flows. Easily integrated with AGV systems and WMS software, creating a fully automated logistics process.
