    One stacker crane with access to four rack rows (two on each side). Great for high-density storage of low/med throughput.

  • Dual crane AS/RS
    Two stacker cranes operate simultaneously in the same aisle to maximize throughput capacity and resiliency.

  • seismic tremor control

    Earthquake countermeasures
    Additional stopper, special racking and other countermeasures can be applied to minimize earthquake damage. Learn more.

Add-ons

  • shuttle cart, powered cart

    Shuttle Cart
    Electrically powered cart transports pallets to the convenient location for loading/unloading.

  • end-of-aisle conveyor

    End-of-aisle conveyors
    Conveyors automatically transport pallets to and from load/unload stations. Can also transfer pallets to/from STVs.

  • Rack side conveyor
    Placing the in/out conveyor beside the AS/RS makes it smoother to supply loads to press machines or processing machines.

  • rail-guided vehicle, RGV, sorting transfer vehicle

    Sorting Transfer Vehicle (STV)
    Rail-guided vehicle system STV connects AS/RS aisles to in/out conveyors.

  • pick-to-light for rack side

    Rack-side Pick-to-Light
    The sides of the AS/RS rack are used as picking windows. A sliding shutter is installed at each picking window to ensure operator safety by preventing stacker crane access while the shutter is open. Lean more.
