Mobile Pallet Racking

The AR Mobile motorized mobile rack system is a high-density storage solution in which racking structures are mounted on motorized bases that travel laterally on floor rails. This design eliminates fixed aisles and opens only the required working aisle on demand, increasing storage capacity by up to 95% compared with conventional selective pallet rack system.

The system also maintains direct access to every pallet, combining the selectivity of a conventional rack with the compaction of a high-density storage solution.

AR Mobile is particularly effective in cold storage facilitys and freezer applications because it allows storage to be compacted, reducing the volume of air that must be refrigerated. In cold environments — where energy costs are constant and significant — every cubic metre optimized has a direct impact on the profitability of the installation.

The system can also incorporate a parking or night mode, which spaces the bases evenly when the installation is not in use. This promotes the circulation of cold air between pallets, improves thermal uniformity, and optimizes the performance of the refrigeration equipment.

Safety in the AR Mobile system is based on an integrated and redundant design. It incorporates laser protection barriers at the aisle entry points to detect the presence of an operator before any base movement begins. If a person enters the open aisle, movement is immediately halted.

The system also includes mechanical anti-collision devices, emergency stop buttons accessible from within the aisle, and audible and visual warnings prior to base movement. All safety functions comply with the applicable European machinery and racking standards.

Yes. Installing an AR Mobile system requires the floor rails to be integrated into the concrete slab. In new-build projects, this can be planned from the outset, keeping additional work to a minimum. In existing warehouses, saw-cutting and re-filling the slab is required to seat the rails correctly.

AR Racking’s technical team works alongside civil contractors to specify the correct rail installation method, slab loading requirements, and flatness tolerances.

The AR Mobile system can operate in several modes to suit different operational requirements. In automatic mode, a single button press opens the selected aisle; in manual mode, the operator has direct control of each base independently. A multi-aisle mode is also available as an option, allowing several aisles to be opened simultaneously for higher-throughput operations.

The system can be integrated with warehouse management software (WMS) to automate aisle selection based on the incoming picking or replenishment task.

The AR Mobile system is compatible with various handling equipment, including counterbalance forklifts, reach trucks, and other handling machines — provided that the equipment dimensions are compatible with the working aisle width. VNA trucks can also be used in combination with mobile bases to further increase storage density in applications where the investment is justified.

AR Racking’s Traceability 4.0 system allows the main structural components of the racking to be identified, tracked, and linked to their full manufacturing and specification records. In the event of damage or a maintenance intervention, this enables the correct replacement components to be identified quickly and accurately.

For a system as dynamic and mechanically active as AR Mobile, component traceability is an important element of long-term maintenance management.

Yes. The AR Mobile system can be adapted to different types of load, not only palletised goods. For example, cantilever arms can be integrated into the mobile base structure to accommodate long loads such as pipes, profiles, or timber. Medium-duty shelving can also be mounted on mobile bases for the storage of loose goods, boxes, or non-palletised products.

Each configuration is designed and calculated individually to ensure that the base motor capacity and structural integrity are compatible with the specific loads and operating conditions.

AR Racking validates its solutions through structural calculation, quality processes, and physical testing at the AR Lab, its in-house laboratory. Bases are tested for load capacity, dynamic performance, and durability under representative operating conditions.

All structural elements are manufactured in compliance with the applicable European standards, and the complete system is assessed as an integrated unit to ensure safe and reliable performance throughout its service life.

The mobile bases are designed to open the working aisle quickly and in a controlled manner. The exact time depends on the width of the system, the number of bases involved, and the travel speed configured for the installation. In typical configurations, a working aisle can be fully open within a matter of seconds.

Yes. Multi-aisle mode can be enabled as an option. This configuration allows several aisles to be opened simultaneously for operations that require concurrent access to multiple locations — for example, during intensive picking or replenishment periods. However, enabling this mode requires a careful review of the safety system.

AR Racking’s technical team will assess the suitability of multi-aisle operation during the project design phase.

The AR Mobile system complies with the European standards applicable to industrial racking, and specifically with ANSI/RMI MH16.1 (or the equivalent international standard EN 15512) for the structural design and calculation of the racking elements. The motorized base mechanism complies with the Machinery Directive and the associated safety standards for automated industrial equipment.

Full CE marking is applied to the system as required by European regulation.

The number of racking bays that can be grouped into a single mobile block is always defined on a project-specific basis and depends on the available floor area, the total load to be carried, the motor capacity, and the structural parameters of the installation.

AR Racking’s engineering team sizes the motor units, rail system, and structural connections to ensure safe and efficient operation for any configuration.
