Four-way pallet shuttles

Flat shuttles move pallets in any direction inside dense racks.

Commercial

Sold and running daily at many sites, with reference customers you can call.

What it does

A flat shuttle runs on rails inside the rack, slides under a pallet and carries it in four directions. Lifts move shuttles and pallets between levels, so the racks need almost no aisles.

Best for

  • Dense pallet storage, including cold stores
  • Few SKUs in high volumes
  • Buildings where every square metre costs

Watch out for

  • Racks and lifts are a fixed investment.
  • Lift capacity often limits throughput.
  • Ask for reference sites in your region.

What it costs

Vendors quote per project and do not publish unit prices.

Why we rate it commercial

Four-way shuttles are an established way to store pallets. Quicktron brought QuickCube to US buyers at MODEX 2026, so overseas references are still few.

Who makes it in China

Ask every vendor

  • How many pallets per hour in and out, at a reference site?
  • What happens when a lift goes down?
  • Can the system run at our cold-store temperature?
