Gravity Flow Racking System: The Ultimate Global Procurement, Engineering & ROI Guide

Calculations account for the coefficient of rolling friction, maximum and minimum pallet gross weight, and pallet underside condition. Standard gradients range between 2.5% and 3.5% (approx. 35 to 45 mm slope per linear meter). Cold room installations or rough softwood pallets require steeper gradients (up to 4.0%), paired with precisely positioned centrifugal brake rollers to prevent runaway speeds under maximum weight loads.

Without centrifugal brake rollers, trailing pallets accelerate down the slope, resulting in severe impacts against leading pallets or front end stops. Furthermore, pallet backpressure increases with lane depth: in a 10-pallet deep lane, the front pallet can experience up to 9,000 kg of static crushing force. Our automatic separator locks trailing pallets behind a mechanical catch until the front pallet is completely lifted away by the forklift, protecting operator safety and mast hydraulics.

Because gravity live storage concentrates massive dead loads and dynamic kinetic forces within deep compact bays, floor slab flatness must conform strictly to DIN 18202 or TR34 FM2 standards. Point-load calculations on baseplates are significantly higher than selective racking, requiring reinforced Hilti anchoring, heavy floor shim plates, and structural column upright protectors at both replenishment and discharge faces.

Through our dedicated 18000 Series Interservice programme, certified engineers evaluate roller bearing runout, centrifugal brake resistance, end-stop weld fatigue, and safety separator spring mechanisms. Damaged rollers can be replaced individually without dismantling entire bed modules, keeping warehouse downtime to a minimum.

Gravity flow racks inherently guarantee First-In, First-Out (FIFO) batch movement. Pallets or cartons are inducted at the higher rear replenishment face and automatically glide downward to the front pick face. Stock pickers can only access the oldest inventory batch first, eliminating manual stock rotation, obsolete date code risks, and costly handling errors in food, chemical, and pharmaceutical warehouses.

Pallet flow racks handle full palletized unit loads (typically 500 to 1,500 kg per pallet) handled by counterbalance or reach trucks on heavy-duty steel roller tracks equipped with brake rollers. Carton flow racks handle lighter individual tote boxes or corrugated cartons (10 to 40 kg per item) picked by hand or integrated with automated pick-to-light or conveyor pick modules.

Stalls are usually caused by defective bottom runner boards or debris on the roller bed. My Interack engineers lanes with optimal pitch tolerances and tests actual pallet samples prior to installation. If a stall occurs, our systems feature manual restart assist mechanisms, or operators can safely nudge the lane using an adjacent pallet without entering dangerous dynamic live lanes.

Yes. In addition to extensive installations across Malaysia, My Interack regularly completes racking projects in Singapore and supplies containerized systems to global buyers. We coordinate structural engineering calculations, custom container packing to protect roller assemblies, export documentation, and on-site assembly supervision.

Because gravity live storage cuts dedicated forklift traffic aisles down to just two, reduces forklift transit cycles by 40-60%, eliminates electrical utility costs for dynamic movement, and virtually eliminates expired stock write-offs, most logistics hubs recover their capital outlay within 14 to 22 months of continuous operation.
