About Bulldog Shuttle Systems
Bulldog Rack offers two revolutionary shuttle solutions designed to transform your warehouse operations. The 4D Shuttle is a fully autonomous system using lifts for X, Y, Z movement - shuttles navigate between levels and aisles without any human intervention for true 24/7 automated operations. The 4D Lite is a game-changer in the industry - shuttles stay on each level permanently while forklifts place and retrieve pallets at the pick face. No need to move shuttles between levels, no complex IT integration required. Both systems dramatically increase storage density while reducing labor costs and improving accuracy.

Bulldog Shuttles In-Motion
Induction, Delivery and Retrieval
Measuring, weighing and scanning each pallet at induction is highly important to ensure loads are properly sized and confirmed. Each in-coming pallet ID is scanned for automatic induction and put away. A shuttle is then sent a pick up task. Once the load is picked up by the shuttle, autonomous pathing routes the shuttle for put away.
Autonomous Charging
Bulldog 4-Way Shuttles include automatic battery charging so maintenance personnel do not have to manually change or charge batteries. The Electronic Control System (ECS) monitors state of charge and when a battery reaches a preset discharge level, the system routes the shuttle to a charging station for a 2-3 hour re-charge.
4D In-Motion
The 4D uses smart and proven pathing technology. Your ERP or WMS is connected the Shuttle WMS and ECS technology and pathing is managed seamless through use of RFID positioning and microchip location tracking. The pathing algorithm uses proven A-Star path finding graphical transverse technology. The shuttles are real time monitored for maximum uptime and reliability.
2D In-Motion
Bulldog's 2D or 2-Way Shuttle is an excellent choice for high density storage when products are stored in bulk and stored and retrieved in full truck load or low SKU production quantities. The 2D shuttles are manually placed within storage lanes and then manage the work from there. Pallets can be counted and indexed depending upon your storage needs. Great replacement for floor or drive-in.

Frequently Asked Questions
The 4D system is fully autonomous - shuttles use integrated lifts to move between levels (X, Y, Z axes) and navigate throughout the entire system without any forklift intervention. The 4D Lite is a game-changer: shuttles remain on their assigned levels permanently. Forklifts simply place and retrieve pallets at the pick face while shuttles handle deep lane storage. No need to move shuttles, no complex IT integration required.
