Fully Automated High Density Pallet Storage: PAS PowerStor

PAS PowerStor is a revolutionary and patented cart-based Automated Storage and Retrieval System (AS/RS), used for deep storage of palletized loads. The PowerStor solution provides the capability for high throughput of large quantities of multiple size loads in large, small or odd-shaped facilities.

Comprised of simple components, the PowerStor system provides the highest density storage and highest throughput capability in the world. PowerStor is extremely flexible in its configuration options and can easily handle multiple pallet sizes at the same time.

Industry-Leading Features:

  • Simplified Technology.
  • Configurable to any building.
  • Designed to prevent downtime.
  • Maximizes space utilization.
  • Ultra-high throughput.
  • Highly reliable and easy to maintain.
  • Satisfies all safety and fire-protection requirements.

Here’s How It Works - Storage

A pallet arrives via conveyor at the Vertical Lift pick-up position. Under the direction of our state-of-the-art performance and monitoring software, PASWare®, the Vertical Lift is then directed to pick the pallet off the conveyor and transfer it to the correct level of storage where it places the pallet on the Pick-Up and Deposit Station.

The software then directs the Aisle/Row Cart Pair to pick the pallet off the Pick-Up and Deposit Station and transport it to the correct row or rack for storage. Once at the correct row, the Row Cart is directed to leave the Aisle Cart and transport the pallet to the correct position in the row where it is placed on the row rails. The Row Cart then returns to the Aisle Cart for the next operation.

Here’s How It Works – Retrieval

PASWare software directs the Aisle/Row Cart Pair to the correct row of storage. Once correctly positioned, the Row Cart travels until it is underneath the pallet being retrieved. The Row Cart then lifts the pallet off the rails and returns to the Aisle Cart. From there, the Aisle/Row Cart Pair moves to the Pick-Up and Deposit Station where the pallet is deposited onto the stand. The Aisle/Row Cart Pair is then ready for the next operation.

Semi-Automated High Density Pallet Storage: PAS Voyager

PAS Voyager™ delivers a semi-automated solution for high-density pallet storage that:

  • Improves throughput in deep racks
  • Reduces labor needs and miles traveled on fork trucks
  • Reduces product damage
  • Increases storage capacity
  • Improves existing employee productivity
  • Is energy efficient

Additional storage can be added to your warehouse because Voyager is not deterred by either deep or stacked racks.

Your solution can be customized for your specific warehouse needs in a way that helps you meet your budget and cost goals and still delivers a scalable, measureable return-on-investment.

The Voyager system is ideal for:

  • Freezer/Coolers - operates in -22C environment.
  • Food/Beverage - carries up to 3,000 lbs and increases turns and throughput.
  • Pharmaceutical - increases controlled environment.
  • LEED Certified Warehouses - energy efficient system.
  • Existing Spaces – increases high density storage capacity.

Here’s How It Works – Storage

Your fork truck places the Voyager shuttle unit on the row within your racking structure where the pallet is to be stored. Next, your fork truck places the pallet and its load on the rails over the Voyager shuttle unit within the racking structure. The Voyager shuttle unit then lifts the load and zips it to the correct location, gently depositing it there and swiftly returns to the end of the row to await the next pallet to be stored.

Here’s How It Works – Retrieval

The Voyager shuttle unit zooms at 200 fpm to the stored pallet, lifts it and carries it to the end of the row where your fork truck removes the pallet from Voyager. While your fork truck is delivering the pallet to its destination, Voyager zooms  into the rack to fetch the next pallet. Your pallet is ready when the fork truck arrives to pick it up.


Want to ease into your solution? Worried about future economies of scale? Scaling is no problem!

Want to ramp up the automation and performance of the Voyager system? You can always add a PAS Vertical Lift Device (VLD) and eliminate the need for fork trucks to place Voyager into the correct row. This also allows you to extend your racking structure up higher to increase storage capacity.

Drive-In Pallet Rack

This system provides very dense storage. It is typically used when there are many of the same types of products (SKU's). It can significantly reduce the storage space compared to the traditional selective rack. This system can be configured to meet specific load sizes, weights and seismic zones.

Drive-in racking is designed for the storage of homogenous products. It accommodates a large number of pallets for each SKU. This system makes great use of both floor and vertical space.

The installation is made up of a set of racking units that form inner loading aisles with support rails for the pallets. The fork-lift trucks enter these inner aisles with their load held higher than the level at which it is to be deposited.

Pallet Flow / Live Pallet Racking

Live storage racking for palletized loads are compact structures that incorporate roller track sections placed on a sloped lane to allow the pallets to slide over them. The pallets are put in at the highest part of the rolling section and move by the force of gravity and at a controlled speed towards the other end where they remain until they are ready to be removed.

Live storage pallet racking is ideal for the following areas where palletized loads are handled.

Perishable goods warehouses.
Intermediate warehouses between two working zones.
Dispatch areas, where pallets need to be removed quickly.
Holding warehouses (prepared orders, classification channels in automatic circuits, etc).

Live storage enables perfect rotation of stored products, with the FIFO (First-in, First-out) system, where the first pallet to be put in is the first to be taken out. When the first pallet is taken out, the others move forward one position. This makes it ideal for storing perishable goods.

Push-Back System

This system operates very simply.

Each level of racking includes two or three parallel trolleys at different heights. The fork-lift places the first pallet on the highest set of parallel trolleys. When loading the second pallet, the fork-lift pushes the first one along until it reaches the next set of trolleys and deposits the pallet on these. If the installation has been designed to store four pallets, the operation is repeated with the third pallet and the last one is rested directly on the rolling rails, rather than on the trolleys, after pushing the previous three pallets forward.
When unloading pallets, the modus operandi is reversed in such a way that when the first pallet is removed, the others move forward one place towards the aisle.

The system can be adapted to store two, three or four pallets deep. Once the model and measurements of the pallets have been analyzed, together with the available space and the type of forklift to be used, the number of pallets can be specified.

In order to choose the most suitable system, an analysis should be made of each customer's needs regarding capacity, number of SKU's and operating system.

Selective Pallet Rack

The most common rack configuration used. This system can be configured to meet specific load sizes, weights and seismic zones. The rack line is packed with many value added features, from engineered components to sophisticated manufacturing to comprehensive quality.

Structural Racking

Made from high resistant, hot rolled structural steel. This rack is designed for higher capacity applications.
Structural steel components can be used in multiple configurations including selective pallet, drive-in, push-back and more. They can be integrated with roll form components to provide a more economical alternative where a structural system is required.
