Automated Pallet Shuttle System: High Throughput and Maximum Storage Density

Multilevel shuttle sets new standards for throughput, flexibility and efficiency. It consist of three coordinated by software modules with seamless interfaces: shuttle car, high-performance vertical lift and developed special carrier that moves the shuttle car to exact location on a certain level. In analogy to the small-part-shuttle technology, the Multilevel shuttle system enables multi-deep storage and highly dynamic commissioning of various types of pallets. All that ensure a high storage density.

With its modular structure, the Multilevel Shuttle system is totally adaptable to different customer needs. The fields of application for this pallet shuttle system are suitable for: cold storage, buffer storage, dispatch warehouses, sequence storage, commissioning warehouses or supply warehouses.

Multilevel shuttle system is ideal for upgrading of existing warehouses.

All modules of the system are construed also for deep-freeze conditions and are suitable for a wide variety of unit load.

Due to the innovative energy storage systems, charging concepts has smart energy management, and system also has a low energy consumption that reduces costs. The energy balance and thus the operating costs play an essential role, especially in cold storage.

The integral control of the system turn on/off different modules to achieve better operations. For example, it is possible to reduce the throughput time of a warehouse in case more important is to improve the utilization of the space at any time.

System initial components are:

  • Shuttle car

Instead of conventional batteries, the Shuttle car is powered by power caps. Recharging of these power caps can take about 8 seconds while the shuttle is being transported by the Carrier. That means continuously 24 hour operation. All Shuttle Cars are fitted with powerful and compact 400 V three-phase motors that handle all travelling and raising/lowering functions. With its powerful motor and power caps, the Shuttle Cars reaches a loading capacity up to 1500 kg and can be quickly transferred and transported. 

  • Lifts

These conveyors transport unit loads to higher or lower levels. With the modular system, we can supply different arrangements as to suit different applications. The stable columns can be fully enclosed if required. Either one or two load-handling devices can be used simultaneously to transfer goods. 

  • Carrier

The Carrier functions as a transport unit for the Shuttle car with or without load and can be repositioned as required with the vertical conveyor. Thanks to the controls concept several Shuttle cars can be assigned to one Carrier at the same time – thus, ensuring scalability for every system solution even afterwards.
Eight running wheels ensure stable, safe transport at mechanical interfaces - therefore easily mastering aisle lengths of up to 120 m. Its lightweight design reduces energy consumption. Also all components are designed for use in cold stores as standard.
A new generation of high-performance power caps plus inductive energy transmission reduce the installation requirements and hence the cost of the investment.
There is a permanent point to point radio link between the Carrier and the Shuttle Car, to ensure maximum functional reliability. All the movements are monitored by the integral control system and compared among each other.
