Navette: scalable multi-level warehouse shuttle
Innovative, independent warehouse vehicle for virtually all transport aids
With the flexible Navette multi-level shuttle, SSI Schaefer offers a solution for increasing efficiency in the storage and picking of trays, totes or cartons in fully automated warehouses.
The Navette is integrated into the steel framework of the automated small parts warehouse aisles. It is guided by travel and support rails and operates as a single component, serving up to eight storage levels – two of them actually in parallel. An important design feature is the fact that it is equipped with two load handling devices (LHDs), such as carton grabs, arranged one above the other. Their distance from one another corresponds to the distance between two rack levels. Each load handling device can transport two trays, totes or cartons.
Operation across storage levels with genuine double cycles
In one load cycle, the Navette moves a total of four transport units simultaneously, serving storage locations on two storage levels in a single operating sequence. So, unlike single-level shuttles, the Navette is able to operate in genuine double cycles. The multi-level shuttle can store and retrieve simultaneously in just one positioning process. This minimises travel times and doubles process efficiency.
The Navette allows access to the widest possible range of articles in the storage aisles and an optimum workflow through parallel processes. System solutions based on the Navette can be precisely tailored to the order volume, the required throughput and the individual article structure, and feature a high degree of scalability both at system level and in the overall design.
Combined with the 3D-MATRIX Solution®, previously inconceivable levels of performance are made a reality. Navette lifts in these solutions act as a link between the conveying system and the individual Navette travel levels. The positioning and number of lifts in the aisle is entirely at the user’s discretion.
Product benefits of the scalable Navette multi-level shuttles

- Stackable up to a height of 24 meters: flexible storage configuration
Navette: the scalable multi-level warehouse shuttle
Highly dynamic goods-to-person picking, in which storage, buffering and individual sequencing can be performed in a single system. Retrievals are prepared for loading exclusively for the relevant connected picking and shipping locations, without bundling and distribution via a downstream conveying system.
