FIFO LIFO Two-Way Pallet Shuttle System with 1200 kg 1500 kg Load Capacity and

The two-way pallet shuttle is an automated pallet handling unit designed for high-density pallet warehouses and deep-lane storage systems. It travels forward and backward within a single rack lane to complete pallet storage, retrieval, lifting, positioning, and placement.

The system supports both FIFO (First-In, First-Out) and LIFO (Last-In, First-Out) storage modes, allowing warehouse projects to select the appropriate inventory flow according to rack layout, access direction, and stock rotation requirements.

Available rated loads are 1200 kg and 1500 kg, with unloaded travel speed of 60–72 m/min and loaded travel speed of 36–54 m/min. The shuttle uses a DC servo motor, mechanical screw lifting mechanism, and LiFePO4 battery system.

In high-density pallet warehouses, common operational requirements usually include:

• FIFO or LIFO inventory rotation
• high pallet storage density
• deep-lane pallet storage and retrieval
• multiple pallet positions within the same lane
• batch pallet handling
• different pallet sizes and rack configurations
• remote or automatic pallet operations
• low-temperature warehouse applications

FIFO is suitable for storage layouts where pallets enter from one side and are retrieved from the opposite side. LIFO is suitable for layouts where pallet storage and retrieval are performed from the same side.

The two-way pallet shuttle supports both operating strategies, making it suitable for warehouse projects with different inventory rotation and access requirements.

The two-way pallet shuttle operates on dedicated rails installed inside the pallet racking system. After receiving a command from the warehouse system or remote controller, the shuttle travels to the target pallet position and performs lifting, lowering, storage, or retrieval.

The vehicle uses a DC servo motor, mechanical screw lifting mechanism, and LiFePO4 battery. Maximum lifting height is 50 mm.

The system supports single pallet storage and retrieval, automatic storage and retrieval, specified quantity handling, manual forward and reverse travel, lifting and lowering, emergency braking, pallet arrangement, and inventory counting.

The standard communication configuration uses a 433 MHz RF remote controller, while WF models support wireless network communication.

This page refers to a two-way pallet shuttle system operating forward and backward within a single rack lane.

It is mainly suitable for:

• palletized goods
• FIFO pallet storage
• LIFO pallet storage
• high-density pallet racking
• deep-lane pallet storage
• 1200 kg or 1500 kg pallet loads
• ambient-temperature warehouses
• low-temperature warehouse applications

Actual project selection should be confirmed according to pallet dimensions, pallet weight, pallet structure, rack rail configuration, storage lane arrangement, inventory rotation strategy, operating environment, and communication method.

FIFO or LIFO suitability depends on the rack access design. The storage mode should therefore be confirmed together with warehouse layout before final system selection.

This product is a two-way single-lane shuttle and should not be treated as a four-way or multi-directional pallet shuttle.

1200 kg and 1500 kg are the available rated load configurations and should be selected according to the actual pallet and goods weight.

60–72 m/min refers to unloaded travel speed, while 36–54 m/min refers to loaded travel speed.

The shuttle uses mechanical screw lifting with a maximum lifting height of 50 mm.

Available pallet configurations include 1200*1000, 1200*800, 1200*1100, 1200*1200, 1000*1200, 1100*1100, 1300*1300, and 1300*1100 mm.

The model coding system can identify rail specification, pallet size, operating environment, communication mode, and customized configuration. No environment code indicates ambient operation, while C indicates a low-temperature version. No communication code indicates RF remote control, while WF indicates wireless network communication. NS indicates a customized model.

DSS uses a 50*148 mm rail with double deceleration holes. DSSA uses a 70*163 mm rail, DSSC uses a 70*130 mm rail, and DSSD uses a 50*148 mm rail with baffle-scanning deceleration.
