Skid Flow Racks

Gravity flow rack systems designed around your production skid fleet — matching roller rail centers to your skid runner dimensions for reliable FIFO lane flow in automotive assembly, heavy manufacturing, and powertrain production environments. Manufactured in Auburn Hills, MI.

Why Choose Modular Solutions Skid Flow Racks

Designed Around Your Skid Fleet

Lane roller rail centers, width, and guide rail geometry are designed from your actual skid drawings — ensuring consistent runner contact and reliable gravity flow with your existing skid inventory.

Production Line Sequencing

Multi-lane skid flow systems present parts in build sequence at the assembly station — eliminating operator searching and reducing line-stop risk from skid mis-sequencing.

Conveyor System Interface

Pick-face discharge heights and roller centerlines can be designed to interface directly with plant conveyor, chain transfer, or tugger delivery systems for seamless in-plant material flow.

AGV and Tugger Compatible

Lane entry and exit positions are dimensioned for your tugger, forklift, or AGV. Push-pull attachment interfaces and AGV positioning datum targets can be built into the lane structure.

Heavy Load Ratings

Lanes are rated for your specific skid gross load — from light assembly skids under 500 lbs to large casting or structural skids above 5,000 lbs — with roller and frame members specified by load calculation.

Plant Floor Space Optimization

Gravity flow eliminates the powered conveyor footprint between storage and line-side, recovering plant floor space for production fixtures, tooling, or operator work zones.

Frequently Asked Questions

What is a production skid and how does it differ from a standard pallet?

A production skid is a flat steel or wood platform, typically without pallet deck boards, that a part or assembly sits on or is welded/bolted to for transport through the plant. Skids often have custom runner widths, steel-frame bases, and load-specific mounting features. Skid flow racks are configured to match the specific skid runner width and overall base dimensions of the customer's existing skid fleet.

Can skid flow racks handle non-standard skid runner widths?

Yes. Skid flow rack roller rails are positioned to match any runner width. Since automotive and heavy manufacturing skids are often custom to each plant, the lane design starts with the customer's skid drawing, not a catalog standard. Both parallel and perpendicular runner orientations can be accommodated.

What load capacity do skid flow racks support?

Skid flow rack lanes are designed to the gross skid load weight specified by the customer. Typical automotive powertrain and body structure skids range from 500 lbs to 4,000 lbs gross. Heavy-duty fabricated steel skids for large castings or assemblies can exceed 6,000 lbs per position, which requires appropriately rated rollers, rail, and structure.

How are skids loaded into and removed from skid flow lanes?

Skids are typically loaded using forklift, tugger cart with push-pull attachment, or robotic transfer cart at the rear of the lane. The skid gravity-feeds forward to the pick face. At the pick face, a pallet jack, forklift, or AGV removes the skid for delivery to the production station. The removal method determines the required pick-face clearance height and floor-level access design.

Can skid flow rack systems be integrated with plant conveyor or transfer systems?

Yes. Skid flow lanes can be designed to discharge directly onto roller conveyor or chain transfer systems. The interface height and roller centerline are matched to the receiving conveyor dimensions. Powered transfer sections can be added at the pick-face end to push skids from the flow lane onto an adjacent conveyor without manual handling.
