Four-Way Shuttle System (4WS)
High-density automated storage designed for flexibility and scalability.
Four-Way Shuttle systems make efficient use of warehouse cube space, supporting high-density storage in a compact footprint. The modular design allows capacity to be extended as your business grows; throughput depends on the system configuration. ICAS Technology, a Singapore-based integrator, designs and integrates these systems.
What Four-Way Shuttle Delivers for Your Operation

How Four-Way Shuttle Works in Your Operation
In a typical flow, the shuttle stores and retrieves loads in the racking on instructions from the WMS or WCS. The exact configuration depends on your layout and load type.
Typical Applications
Where four-way shuttle systems are commonly used
Integration Capabilities
Four-way shuttle systems can be connected to warehouse software, mobile robots and material flow systems. The interfaces depend on your existing systems and are scoped with our specialists.
Frequently Asked Questions
How four-directional movement changes storage density, and how the system scales and integrates.
How does a Four-Way Shuttle differ from standard shuttle systems?
A four-way shuttle can travel in both horizontal directions on a rack level, so it can reach any storage lane on that level. A conventional shuttle moves in a single direction along a lane. Moving between levels is typically handled by a lift.
Can capacity grow as our business grows?
Capacity can usually be extended in a modular system. The options depend on the building, layout and original design, which our specialists plan with you.
What systems does it integrate with?
It can be connected to WMS, WCS, ERP, AMR/FMR solutions, conveyor interfaces, and barcode/RFID systems. The interfaces depend on your existing systems and are scoped with our specialists.
