How Fast is an Automated Pallet Runner / Mole Compared to Forklifts?

When evaluating warehouse efficiency, the question isn’t just about the miles-per-hour of a machine. It’s about pallets per hour, operational flow, and the speed of your entire fulfillment cycle. In a direct comparison, an Automated Pallet Runner, or Mole, fundamentally redefines “speed” in a way that traditional forklift operations within high-density racking simply cannot match, especially within the demanding environment of a cold chain warehouse.

A forklift might travel at 5-8 mph, but that metric is misleading. The true measure is the time it takes to complete a full storage or retrieval cycle. Let’s break down why a pallet shuttle system is exponentially faster where it counts.

The Traditional Drive-In Racking Bottleneck: One Pallet at a Time

In a typical deep-freeze facility using drive-in racking, the workflow is linear and fraught with delays. A forklift operator must:

• Slowly and cautiously enter a narrow, often icy, storage lane.
• Navigate deep into the structure, raising the mast to the correct level.
• Place the pallet, often with limited visibility.
• Carefully back out the entire length of the lane.
• Only then can they travel to pick up the next pallet.

This entire sequential process can take 5 minutes or more per pallet. During this time, the forklift driver is the sole bottleneck, and the main warehouse aisle is losing costly refrigerated air. This slow, high-risk operation directly impacts your throughput and energy consumption.

The Shurack Speed Revolution: Parallel Workflows

An Automated pallet runner shatters this linear bottleneck by introducing a parallel workflow. It decouples the forklift’s task from the in-lane storage task.

Workflow Stage	Traditional Forklift in Drive-In Rack	Forklift with Shurack Pallet Shuttle
Pallet Placement	Forklift drives deep into the lane to place the pallet. (Time: 2-5 mins)	Forklift places the pallet on the shuttle at the very entrance of the lane. (Time: <30 seconds)
In-Lane Travel	N/A (Part of the placement process)	The lithium-powered shuttle transports the pallet to the next available position. (Forklift is already gone)
Next Task	Forklift must reverse out of the lane before getting the next pallet.	The forklift is immediately free to retrieve the next pallet, working in parallel with the shuttle.

This “human-machine separation” is the core of the speed increase. While the shuttle is busy working inside the cold, dense lane, the operator and forklift are already handling the next load in the main, safer aisle. This simple change results in a 30-50% improvement in throughput, effectively doubling the efficiency of each forklift driver.

A forklift operator places the shuttle at the lane entrance, eliminating the need to drive into the high-density racking.

Engineered for the Cold: Speed Meets Reliability

Speed is meaningless without reliability, especially in a -25°C (-13°F) environment where equipment failure can halt operations. The Shurack Sistema de estanterías Pallet Shuttle is built to maintain peak performance in these conditions.

• Q355B High-Strength Steel: Unlike standard steel that can become brittle at low temperatures, our system uses Q355B grade steel. It maintains its structural integrity and impact resistance, ensuring the safety and longevity of your racking investment even with constant temperature cycling.
• Lithium Power (LiFePO4): The 48V Lithium Battery Powered Shuttle is superior to lead-acid in cold environments. It delivers consistent power and supports a rapid-swap system. An operator can change a battery in under 60 seconds, ensuring 24/7 continuous operation without the need for dedicated, heated charging rooms.

The automated shuttle transports a full pallet deep within the storage lane, while the forklift is already handling the next task.

Beyond Pallets Per Hour: The “Speed” of Your ROI

The most crucial speed for any business is the speed of its return on investment. A radio shuttle racking system accelerates your ROI through multiple operational savings:

1. Reduced Energy Costs: By eliminating forklift traffic inside storage lanes, you significantly reduce the exchange of air between the main aisle and the deep-freeze zone. This leads to a documented 22% reduction in refrigeration energy costs.
2. Lower Labor Costs: With doubled operator efficiency, you can handle higher volumes with the same headcount or reduce the number of forklift drivers needed, a significant saving, especially in a tight labor market.
3. Eliminated Rack Damage: The single greatest cause of rack damage—forklift collisions inside narrow lanes—is completely eliminated. This drops your annual rack repair and maintenance costs to near zero.
4. Strict FIFO for Compliance: The system’s intelligence allows for easy switching between FIFO (First-In, First-Out) and LIFO (Last-In, First-Out) modes. This ensures you can meet stringent HACCP and food safety regulations, preventing product spoilage and recall risks.

Conclusion: It’s Not a Fair Race

Comparing the speed of an Automated Pallet Runner / Mole to a forklift is like comparing a specialized surgical tool to a hammer. While a forklift is essential for general transport, the shuttle is a purpose-built instrument for maximizing speed, density, and safety within the storage lane. The true “speed” of the system lies in its ability to transform a slow, sequential process into a fast, parallel operation, delivering gains not just in cycle time, but in energy efficiency, labor productivity, and overall profitability for your cold storage facility.

Frequently Asked Questions for Cold Storage Applications

1. How does the shuttle’s battery and electronics perform in extreme cold (-25°C / -13°F)?
Our shuttles use high-performance LiFePO4 (Lithium Iron Phosphate) batteries, which have superior cold-weather discharge characteristics compared to other chemistries. All electronic components are industrial-grade and sealed for low-temperature operation. The quick-swap battery design avoids issues with charging in damp or cold conditions, ensuring constant uptime.

2. Can the system ensure strict FIFO for food and beverage products?
Absolutely. The system’s control logic is specifically designed for batch management. It can be programmed to operate in a strict FIFO mode, where pallets are loaded on one side of a lane and retrieved from the other. This is crucial for meeting HACCP compliance and managing perishable goods with expiration dates.

3. What happens if a shuttle gets stuck deep inside a frozen storage lane?
We have a robust 15-minute “sister car” rescue procedure. A second shuttle can be equipped with a mechanical retrieval tool. It enters the lane and physically couples with the disabled unit, pulling it back to the aisle for maintenance. No personnel ever need to enter the unsafe, confined space of the storage lane.

4. How does the system handle potential ice buildup on the guide rails?
The racking system, constructed from Q355B steel, is designed to minimize surfaces where significant ice can form. The shuttle’s powerful drive motors and robust polyurethane wheels are engineered to operate effectively even with minor frost. Regular warehouse temperature management and defrost cycles remain best practices.

5. ¿Es el sistema compatible con nuestros WMS y tipos de paletas existentes (GMA, CHEP)?
Sí, nuestro sistema está diseñado para la integración. Proporcionamos interfaces WMS abiertas (API) para conectarse sin problemas con los sistemas de gestión de almacén líderes como SAP EWM u Oracle SCM.
