Frequently Asked Questions

What is a 4-way pallet shuttle?
A 4-way pallet shuttle travels along and across rails inside a racking structure, using lifts to change levels, so it can reach any pallet position without forklifts or fixed aisles. Addverb's Cruiser 360 carries pallets up to 3,300 lb at 4.9 ft/s and positions them within ±0.08 in (±2 mm) using QR code positioning and servo control. -
Should I choose a 4-way pallet shuttle or a stacker crane AS/RS?
Choose a 4-way pallet shuttle when you need dense storage in a wide, medium-height building with throughput that can grow by adding shuttles, and a stacker crane AS/RS when the building is very tall and narrow. A crane runs one machine per aisle, so its throughput and resilience are tied to that aisle. Cruiser 360 shuttles move between lanes, so one shuttle stopping does not block access to stock. -
How much space can a 4-way pallet shuttle save?
A 4-way pallet shuttle saves space by removing forklift aisles and storing pallets deep and tall, so the same building holds far more pallet positions than selective racking. That matters when expansion is expensive: JLL reported US industrial asking rents averaging $10.45 per square foot in Q2 2026. The exact gain depends on clear height, SKU profile and pallet size, so Addverb models it during layout design. -
Can a 4-way pallet shuttle operate in a freezer?
Yes, Addverb's Cruiser 360 4-way pallet shuttle operates from -13°F to 113°F, so the same system can run in ambient, refrigerated and frozen storage. Automating a freezer means operators no longer drive forklifts in sub-zero aisles, and dense racking cuts the cubic footage you pay to keep cold. Doors open less often because pallets enter and leave through fixed infeed and outfeed points. -
When is a 4-way pallet shuttle not the right choice?
A 4-way pallet shuttle is a poor fit when you store only a handful of SKUs in large quantities, where a semi-automated 2-way pallet shuttle or a mother-child system gives similar density for less investment.
