Unlike standard pallet flow, deep lane pallet flow requires significantly more upfront planning and information gathering to ensure the right fit. As a dealer, your ability to qualify these opportunities quickly (and set realistic expectations before your customer falls in love with the idea) is what separates a successful installation from a costly mistake.
Here’s what you need to know before bringing a deep lane pallet flow project to us.
Application Suitability
Before anything else, confirm whether the application actually justifies deep lane pallet flow. The strongest candidates share a few key traits:
- High pallet volumes per SKU, generally 30 or more pallets per SKU
- A strict, non-negotiable need for FIFO (First-In, First-Out) rotation
- Consistent, high-throughput operations, typically manufacturing environments staging large volumes for outbound shipping
For slow-moving inventory or small pallet counts, the investment is difficult to justify and other systems will likely serve your customer better. If the fit isn’t there, say so early, and it protects the relationship.
Pallet Quality and Consistency
Pallet condition is one of the most overlooked factors in pallet flow projects, and one of the most common causes of problems after installation. Here’s what to watch for:
- CHEP or GMA-style pallets are the standard recommendation for reliable performance.
- Recycled pallets with three bottom boards are a known problem: they’re inconsistent and will cause hang-ups.
- Multiple pallet styles within the same lane create operational headaches. We can accommodate special pallets (like plastic pod styles) with full-width rollers, but mixing types in a single lane is difficult to manage.
At 3D Storage Systems, we prefer to test all pallet types before manufacturing. This step eliminates guesswork and ensures we’re specifying the right components from the start.
Performance Expectations: Set Them Early
Even in ideal conditions, occasional pallet hang-ups will occur. This isn’t a defect; it’s a reality of gravity-fed systems, and it’s manageable. But your customer needs to know this before the system goes in, not after.
Make sure end users are trained on how to safely address a hang-up without damaging product or the system. Setting this expectation upfront is part of what a good dealer does, and it protects you from calls after installation.
Weight Range Considerations
Deep lane pallet flow systems must be engineered for the weight range they’ll actually handle. This is a detail that bites projects when it’s overlooked.
A 200 lb pallet placed in a lane designed to control 3,000 lb loads won’t travel properly; the heavy-duty brake will stop it before it reaches the pick face.
Best practice: keep the spread between the lightest and heaviest pallets in a given lane within 1,000 lbs. Dedicating lanes to specific weight ranges is possible, but be aware it reduces flexibility and can increase honeycombing.
Gather actual pallet weights early in your qualification process. This is one of the inputs we need to spec the system correctly.
Clear Height, Pallet Height, and Slope
Clear height, pallet height, and lane depth all factor into whether deep lane pallet flow is viable in a given building. Because the system requires a slope across the full lane depth, there is potential to lose a beam level.
If a four-high rack configuration drops to three-high due to slope clearance requirements, the math on the project changes significantly. Confirm these dimensions before the conversation goes too far, and we can help you run the numbers.
Budget and Alternatives: Lead With the Number
Deep lane pallet flow typically sells for $350 to $450 per pallet position. That’s not a small investment, and it’s worth sharing a rough budget figure early in the conversation. More than a few “must-have pallet flow” projects have ended the moment a realistic number was put on the table, and that’s okay. Better to find out in the qualification stage than after a quote.
If cost becomes a barrier, pushback racking is often the right conversation to pivot to. As a reference point:
- A 5-deep, back-to-back pushback system can typically be installed for roughly half the cost of a 10-deep pallet flow lane, while still delivering meaningful density.
Knowing when to recommend an alternative isn’t losing the sale; it’s how you build long-term credibility with your customers.
When to Confidently Recommend It
When the application checks the right boxes (high pallet volume per SKU, consistent pallet quality, genuine FIFO requirements, and adequate clear height) deep lane pallet flow delivers results that other systems simply can’t match:
- Maximum storage density without sacrificing selectivity at the pick face
- Consistent FIFO rotation by design
- Improved throughput in high-volume staging environments
Used correctly, deep lane pallet flow is a genuinely impressive system. The goal of this checklist is to make sure it ends up in the right applications, where it performs as promised and your customer sees the return on their investment.
Why Partner with 3D Storage Systems
At 3D, we work with dealers, not around them. When you bring us a potential pallet flow project, here’s what you can expect:
- Honest qualification help: if it’s not the right fit, we’ll tell you, along with what we’d recommend instead
- Pre-manufacturing pallet testing to confirm specifications before a single component is built
- End-to-end project support from layout through installation
- A partner who stands behind the system after it’s in
A well-specified, properly installed deep lane pallet flow system is one you’ll be proud to point to. That’s what we’re working toward together.
Have a project in mind? Send us your specs.
Share the basics: pallet counts, SKU profile, building dimensions, and product weight range, and we’ll help you qualify the opportunity and determine whether deep lane pallet flow is the right call. If it is, we’ll build the solution with you from start to finish.
