Which Brands Offer Pallet Shuttle Systems, and How Do You Choose?

If you're researching pallet shuttle systems, you've probably noticed that almost every supplier promises higher storage density, better throughput, and lower operating costs.

But here's the problem: not every pallet shuttle system works the same way.

Some systems use a remotely controlled shuttle that travels inside a deep storage lane while a forklift handles pallet transfers. Others use autonomous shuttles that move across multiple aisles and levels as part of a fully automated warehouse.

Those are very different investments.

So, rather than asking which brand is the best, I'd start with a more useful question: Which type of pallet shuttle system fits the way your warehouse actually operates?

Let's look at several established suppliers, compare their publicly documented solutions, and work through the factors I'd evaluate before requesting a quotation.

1. Which Companies Offer Pallet Shuttle Systems?

If you're comparing pallet shuttle systems, I'd start by looking at the technology each supplier offers, how it fits your warehouse, and whether the company can deliver the complete system—not just the shuttle equipment.

Here are several suppliers worth considering, starting with Zhuku / HEGERLS.

Zhuku / HEGERLS

Zhuku is a warehouse automation systems integrator with its own HEGERLS brand, supported by manufacturing and R&D capabilities. Its solutions cover both pallet shuttle technology and broader automated warehouse systems.

Depending on your operating requirements, you can evaluate:

• Four-way shuttle systems: Designed for automated pallet storage and retrieval, with shuttles moving in multiple horizontal directions within a compatible rack and rail system.
• Two-way shuttle systems: A practical option for high-density pallet storage where forklifts transfer pallets at lane entrances and the shuttle handles movement inside the lane.
• Integrated warehouse automation: Solutions that can combine shuttle equipment, storage racking, lifts, conveyors, and warehouse management and control systems according to the project requirements.

What makes Zhuku / HEGERLS worth including on your shortlist is the opportunity to evaluate the storage structure, equipment, and control-system requirements as one coordinated project.

If you're considering a four-way shuttle AS/RS, don't focus on shuttle speed alone. Ask how the proposed system will handle your peak pallet movements, lift capacity, traffic management, WMS/WCS integration, and future expansion.

For a meaningful comparison, provide the supplier with your warehouse dimensions, pallet specifications, SKU profile, and inbound and outbound throughput targets. That will help determine whether a two-way shuttle, four-way shuttle, or another storage configuration is the better fit.

You can explore the company's warehouse automation solutions at Zhuku.

Mecalux / Interlake Mecalux

Mecalux offers a semi-automated Pallet Shuttle system in which a motorized shuttle moves pallets along rails inside compact storage channels. An operator uses a forklift to position the shuttle and a tablet to control its operations.

This approach is worth considering if you want to store pallets several positions deep, reduce forklift travel inside rack lanes, and improve space utilization without immediately moving to a fully automated warehouse.

AR Racking

AR Racking offers the AR Shuttle, a semi-automated pallet storage solution using powered shuttle carts inside the rack structure.

Its published product information covers FIFO and LIFO configurations, cold-storage applications, and inventory counting through shuttle sensors. The system is positioned for operations that need compact storage and frequent pallet movements without requiring forklifts to enter the storage lanes.

SSI SCHAEFER

SSI SCHAEFER offers pallet shuttle systems and storage-retrieval equipment as part of its broader automated warehousing portfolio.

Its approach is particularly relevant if you're evaluating more than the shuttle vehicle itself. Integrated engineering, control technology, and warehouse software can be important when you need to coordinate automated storage with other warehouse processes.

Swisslog

Swisslog offers several shuttle-based storage solutions, including PowerStore, a bidirectional pallet shuttle system, and four-way shuttle solutions such as AgileStore and WonderStore.

The distinction is important. A bidirectional shuttle travels along its designated storage channel, while a four-way shuttle can move in multiple horizontal directions within the appropriate system configuration.

Swisslog is worth evaluating if you're comparing different automation architectures or planning a broader integrated intralogistics project.

Other suppliers to consider

Depending on your location and project scope, you may also want to evaluate:

• Movu Robotics: Offers the atlas four-way pallet shuttle system for automated, high-density pallet storage.
• Daifuku: Provides a broad warehouse automation and material-handling portfolio. Ask for the specific pallet shuttle architecture proposed for your application.
• Spacemaker Systems: Publishes two-way and four-way pallet shuttle offerings, including the DualAxis Pro and QuadAxis Pro product families.

Check each supplier's current product documentation, regional availability, service coverage, and project references before making a final shortlist.

2. First, Decide Which Type of Pallet Shuttle You Need

Before comparing brands, I'd separate the options into two main categories.

These are general distinctions, not universal specifications. Individual systems differ, so check the actual configuration offered by each supplier.

When would I choose a two-way shuttle?

Suppose your warehouse holds large quantities of the same product, and pallets are stored in deep lanes. Forklifts can bring pallets to the lane entrance, while the shuttle handles movement inside the rack.

In this situation, a two-way pallet shuttle system may provide the density improvement you need without the cost and complexity of a more extensive automated warehouse.

It is particularly worth evaluating when your SKU profile is relatively concentrated and you can organize inventory into suitable lanes.

When would I consider a four-way shuttle?

Now imagine that your warehouse handles more SKUs, has frequent inbound and outbound movements, and needs to allocate storage locations dynamically.

A four-way shuttle system may provide greater routing flexibility, especially when integrated with lifts, conveyors, and warehouse control software.

But flexibility comes with additional design requirements. You need to evaluate shuttle scheduling, lift capacity, traffic conflicts, software integration, and how the system performs during peak demand.

Don't choose a four-way system simply because it sounds more advanced. Choose it when its additional flexibility solves a real operational problem.

3. How Should You Compare Pallet Shuttle Brands?

Once you've chosen the general system architecture, I'd compare suppliers across six areas.

1. Storage density and warehouse layout

Ask each supplier to calculate the number of usable pallet positions based on your actual building dimensions.

The calculation should account for columns, clear height, fire protection, aisle requirements, structural constraints, and equipment access—not just the rack footprint.

A system with impressive theoretical density may deliver fewer usable positions once these factors are included.

2. Throughput under your actual workload

Don't accept a throughput figure without asking how it was calculated.

I would request a clear explanation of:

• Inbound and outbound pallet movements per hour
• Whether the figure represents peak or sustained performance
• The number of shuttles and lifts included
• Assumed travel distances and task distribution
• How inbound and outbound tasks compete for shared equipment
• Expected performance during equipment interruptions

A supplier that can explain its assumptions and demonstrate how the system meets your workload is more useful than one that simply quotes a high headline number.

3. Pallet and load compatibility

Check the exact pallets you use, including their dimensions, load weight, base construction, condition, and any overhang.

Don't assume that a shuttle designed for one pallet type can automatically handle another. Plastic pallets, wooden pallets, different runners, and damaged pallet bases may affect compatibility.

For cold storage or other demanding environments, confirm the temperature range and the suitability of the complete system—not just the shuttle vehicle.

4. Software and integration

Ask how the proposed system will connect to your existing warehouse management system (WMS), enterprise resource planning (ERP) platform, and other material-handling equipment.

You'll want to understand task assignment, inventory tracking, exception handling, equipment monitoring, and recovery after faults.

For four-way systems in particular, the warehouse control system (WCS) plays an important role in coordinating shuttle movements, lifts, and transfer points.

Make sure the supplier explains what is included in the software scope and which interfaces or custom integrations would cost extra.

5. Maintenance and local support

A competitive purchase price won't help much if a failed shuttle leaves a critical storage area unavailable.

Ask suppliers about spare-parts availability, response times, remote diagnostics, technician coverage, preventive maintenance, battery replacement, and operator training.

I'd also clarify who is responsible when a problem crosses several systems—for example, when a shuttle fault affects a lift sequence or conveyor operation.

One supplier taking responsibility for the integrated system can be valuable, but you should verify the actual contractual scope rather than assume it is included.

6. Total cost of ownership

Compare more than the initial equipment price.

Your evaluation should include:

• Racking and shuttle equipment
• Lifts, conveyors, and transfer stations
• Software and integration
• Installation and commissioning
• Maintenance and spare parts
• Energy consumption and battery replacement
• Operator requirements and training
• Future expansion costs

A lower-cost system may be the better choice for a straightforward warehouse. A more automated system may justify the additional investment if it reduces labor requirements, improves flow, or supports a workload that a simpler system cannot handle.

The right comparison is the cost of achieving your required operating performance over the expected service life.

4. A Simple Example: Which System Would You Shortlist?

Let's compare two hypothetical warehouses.

Warehouse A: High volume, relatively few SKUs

You store large quantities of a limited product range. Pallets move in and out in batches, and forklifts already handle the receiving and dispatch operations.

I'd start by evaluating two-way pallet shuttle systems from suppliers such as Mecalux or AR Racking. Their semi-automated approach may provide the density and productivity you need without requiring a complete automated storage and retrieval system.

Warehouse B: More complex automated pallet handling

You handle a broader product range, need flexible access across storage areas, and want inbound and outbound tasks coordinated automatically.

I'd include four-way shuttle solutions from suppliers such as Swisslog or Movu Robotics in the initial evaluation. I'd then compare their proposed layouts, throughput models, control systems, integration scope, and support arrangements.

These are starting points, not final recommendations. A warehouse's SKU count alone does not determine the best system. Order patterns, pallet turnover, building constraints, and peak throughput requirements can change the result.

5. What Should You Send Suppliers Before Requesting a Quote?

You can get much more useful proposals if you provide the same information to every supplier.

Prepare a short project brief covering:

• Building: Length, width, clear height, column positions, and any structural limitations
• Inventory: Number of SKUs, total pallet positions, pallet dimensions, and maximum load weight
• Operations: Average and peak inbound and outbound pallet movements per hour
• Flow requirements: FIFO, LIFO, or a combination
• Environment: Ambient, chilled, frozen, dusty, or other special conditions
• Existing systems: WMS, ERP, conveyors, lifts, and other automation
• Expansion: Expected inventory growth and future throughput requirements
• Commercial scope: Installation, commissioning, software, maintenance, and local support

If possible, include a warehouse drawing and a sample of your daily order or movement data.

That allows suppliers to assess the actual problem instead of designing around assumptions. It also makes their proposals much easier to compare.

FAQ

Which brand offers the best pallet shuttle system?

There is no single best brand for every warehouse. Compare suppliers based on system architecture, achievable throughput, storage density, software integration, local support, and lifecycle cost. The best option is the one that meets your requirements with a credible technical and commercial proposal.

Are two-way and four-way pallet shuttle systems interchangeable?

No. They have different movement capabilities and may require different racking, transfer equipment, controls, and operating processes. Confirm which architecture a supplier is proposing before comparing prices or performance claims.

Are pallet shuttle systems suitable for cold storage?

Some are. For example, AR Racking publishes cold-storage suitability for its AR Shuttle, and Swisslog describes cold-storage applications for its four-way shuttle portfolio. You should still confirm the specified temperature range, battery performance, materials, and maintenance requirements for the exact configuration.

Can I add more shuttles later?

Some systems are designed to scale, but expansion depends on the original architecture and available capacity in lifts, transfer points, conveyors, and software. Ask suppliers to explain the cost and performance implications of adding shuttles in the future.

Should I choose a supplier that manufactures both the racking and shuttle?

An integrated supplier can simplify design coordination and responsibility for system compatibility. However, that alone doesn't guarantee the best outcome. Evaluate engineering quality, references, integration capability, spare parts, and after-sales support alongside the supply model.

Final Thoughts

Choosing a pallet shuttle system is less about finding the most impressive brand and more about finding the right match for your warehouse.

Start with your inventory profile and movement requirements. Decide whether a semi-automated two-way system or a more flexible four-way AS/RS makes sense. Then compare suppliers using the same layout, throughput assumptions, integration requirements, and lifecycle-cost model.

If you're currently evaluating options, I'd suggest preparing your warehouse data before requesting quotations. A little work upfront can help you avoid comparing systems that solve entirely different problems.
