Australian Frozen Food Company 80 Percent Storage Density Gain with Radio Shuttle Rack Cold Storage System

Project Overview

Our client, a major Australian frozen food manufacturer specializing in frozen french fries, required a high-density cold storage solution for their new distribution center. Operating at extreme freezer temperatures between -25°C and -35°C, the facility needed to accommodate 10,000 pallet positions with standard 1m x 1m x 1m pallets carrying 800kg of frozen product each. The company sought to maximize storage density while maintaining efficient FIFO inventory rotation for their frozen food products.

Challenge

The client faced several critical challenges in their cold storage operations:

• Extreme Temperature Environment: The warehouse operates continuously at -25°C to -35°C, requiring racking components and shuttle equipment that can withstand severe cold without degradation in structural integrity or operational performance.
• Space Optimization: Real estate and refrigeration costs for freezer warehouses are significantly higher than ambient facilities. Every cubic meter of freezer space represents substantial capital and ongoing energy expenditure.
• High Volume Throughput: With 10,000 pallet positions to manage, the system required efficient loading and unloading processes to minimize door-open time and maintain stable freezer temperatures.
• FIFO Inventory Management: Frozen food products require strict first-in-first-out rotation to ensure product quality and prevent extended storage beyond shelf life.
• Australian Standards Compliance: All racking structures must meet AS 4084:2012 steel storage racking standards for workplace safety certification in Australia.

Solution

We designed and delivered a comprehensive Radio Shuttle Rack System tailored specifically for the client's frozen food cold storage requirements. The solution included:

• Deep Lane Radio Shuttle Racking: Storage lanes configured up to 35 meters deep with rail-guided shuttle carts, achieving 80% greater storage density compared to conventional selective pallet racking within the same building footprint.
• Cold Storage Grade Shuttle Carts: Each shuttle cart equipped with 24V 60Ah lithium batteries specifically rated for sub-zero operation, featuring anti-frost positioning sensors and low-temperature optimized power management systems.
• Freezer-Grade Structural Components: All racking frames and rails fabricated from Q235B cold-rolled steel with hot dip galvanized surface treatment, providing superior corrosion resistance in the high-humidity freezer environment.
• Wireless Remote Control System: 2.4GHz remote controllers with LCD displays enabling operators to manage shuttle operations without prolonged exposure to freezer temperatures, with optional WiFi connectivity for remote monitoring from the warm control room.
• Semi-Automatic Operation: Forklift operators place pallets at the lane entrance and the shuttle cart automatically transports them deep into the storage lane, reducing forklift travel distance by up to 70% and significantly lowering door-open frequency.

Implementation

The project was executed in three phases to align with the client's production schedule:

Results

The Radio Shuttle Rack system delivered outstanding results for the client's frozen food distribution operations:

Key Performance Indicators

• 10,000 Pallet Positions configured across multiple deep-lane modules within the freezer warehouse
• 800kg Load Capacity per 1m x 1m x 1m pallet, optimized for frozen french fry packaging
• -35°C Operational Rating with cold storage grade lithium batteries maintaining full performance
• 80% Density Improvement compared to the client's previous conventional selective racking layout
• 99% Inventory Accuracy achieved through shuttle position tracking and lane management system
• 25% Energy Reduction in refrigeration costs due to 60% shorter door-open duration during pallet handling

Client Feedback

The client's operations director commented: "The radio shuttle rack system has transformed our frozen storage operations. We achieved significantly more storage capacity within our existing freezer building, and our energy costs have dropped noticeably. The shuttle carts perform reliably even at minus 35 degrees, which was our primary concern. The installation team was professional and completed the project on schedule."

Conclusion

This project demonstrates the effectiveness of Radio Shuttle Rack systems for large-scale frozen food cold storage applications. By combining deep lane high-density racking with cold storage grade automation technology, food companies can dramatically improve warehouse space utilization while reducing operational costs. Our turnkey project delivery including design, manufacturing, shipping, installation, and commissioning ensured a seamless experience for the Australian client, with full compliance to AS 4084 standards.
