Automated Warehouse Shuttle System

The RFSJ-1500 is a mechanical four-way pallet shuttle developed for automated pallet storage with a rated load capacity of 1500 kg. Unlike hydraulic lifting models, this series uses a mechanical cam lifting structure. Its main design feature is the 126 mm ultra-low body, which helps reduce the vertical space occupied by the shuttle itself.

Two body configurations are available. The RFSJ-1145-0980-126(-LD) measures 1145 × 980 × 126 mm, while the RFSJ-1145-0850-126(-LD) measures 1145 × 850 × 126 mm. According to the product design data, the low-profile structure can improve storage capacity by approximately 8%–10%. This makes the automated warehouse shuttle system suitable for projects where more usable storage locations are required within an existing building height.

The mechanical structure also keeps the lifting and direction-changing mechanism relatively simple, which can be useful in warehouse projects that place importance on equipment accessibility and long-term maintenance.

The RFSJ-1500 uses mechanical cams for lifting and direction changing. It does not require a hydraulic oil circuit. As a result, the equipment avoids issues related to hydraulic seal aging, oil leakage, or changes in hydraulic oil condition in low-temperature environments.

Mechanical transmission also reduces the number of hydraulic-related maintenance items. For buyers comparing different heavy-load shuttle structures, this gives the RFSJ-1500 a clear technical position: a low-body mechanical solution for 1500 kg pallet handling.

Its unloaded maximum travel speed is 1.5 m/s with an acceleration of 1 m/s². Under load, the maximum speed is 1 m/s with an acceleration of 0.3 m/s². Positioning accuracy is ±2 mm, precise positioning takes 2.5 seconds, and both lifting and direction-changing time are 3 seconds.
