It’s hard to contain the excitement felt by supply chain, logistics, fulfillment and warehouse professionals when it comes to 4D pallet shuttle AS/RS solutions.

The Rainbow Dynamics 4D pallet shuttle system offers scalable and flexible solutions for increasing pallet density, inventory accuracy and operator safety. Additionally, this autonomous storage and retrieval system reduces labor, training and MHE resources.

Unlike 2D pallet shuttle solutions, which require manual operations to move shuttles from level to level, Rainbow’s 4D shuttles are transported by way of automated lifts. Integrated conveyor systems induct pallets for inbound operations and deliver retrieved pallets for outbound order fulfillment.

The system handles various sized pallets weighing up to 4,400 lbs. Maximum running speed is 1.6m/s unloaded, 1.5m/s loaded. Rainbow Dynamics pallet shuttles can operate in -13° F, making the system ideal for cold chain and frozen environments.

System software is AI-enabled and can perform periodic re-positioning of pallets to optimize throughput. All throughput optimization processes are designed to meet customer requirements, taking into consideration such parameters as peak operating hours, fast mover products, LIFO and FIFO.
