Gravity Flow Rack

Gravity Flow Rack

Code: FR-28 · Gravity flow rack, Φ28 lean pipe with roller tracks. Designed to order; drawings, BOM and cut list are ready for the 1800×600, 4-level configuration.

FIFO line-side supply rack for assembly lines: component bins are loaded from the back (logistics side) and roll forward on roller tracks inclined 5–8° towards the operator; empty bins return on the bottom level. The Φ28 plastic-coated steel pipe frame with DND joints lets you re-set the number of levels, the slope and the track spacing yourself when bins change — no welding. Tracks are chosen to suit the bin base (400×300 / 600×400 plastic bins, corrugated PP boxes, trays).

Specifications

  • Frame: Φ28 steel pipe, 1.0 mm wall, plastic-coated; DND joints D-S1/S2/S3/S4, handle joint D-S12B
  • Size: L 1200–2400 × D 600–1200 × H 1500–1800 mm (per drawing)
  • Levels: 3–5 supply levels + 1 empty-bin return level
  • Roller tracks: PP with Φ28 wheels at 33 mm pitch, or aluminium with Φ36 PP wheels; 30 kg/m
  • Slope: 5–8° (depending on bin weight)
  • Load: 100 kg per level (distributed)
  • End stop: end caps / custom stop bar
  • Accessories: kanban board, A4 card pocket, light, Φ75 casters (mobile rack)
  • Production: 5–7 working days for the standard 1800×600 design; 10–15 working days for new layouts (incl. drawing approval); flat-packed with drawing or installed at your factory
  • Warranty: 3 years on the frame; 12 months on ESD decks, electrical fittings and casters

How to choose

  • Light 400×300 bins (<10 kg) → plastic tracks, 6–7° slope.
  • Heavy 600×400 bins (10–25 kg) → aluminium tracks with Φ36 wheels, 5° slope, 2–3 tracks per level.
  • Load from the back, pick from the front (true FIFO) → depth ≥ 900 mm with an empty-bin return level.
  • Rack has to move with the layout → add casters with brakes.

TESTING & HANDOVER: slide test with your actual bins, slope adjusted on site, acceptance report; drawing and joint BOM supplied so you can extend it yourself.

FAQ

  • What slope lets bins roll without tipping? — 5–8° depending on weight; lighter bins need more slope. PRIMEAG adjusts it on site at the joints.
  • How long do plastic roller tracks last? — 2–3 years with plastic bins; cartons wear them faster, so use aluminium tracks.
  • Can I add levels myself? — Yes: pipe + joints + tracks, with a 5 mm Allen key.
  • Can you design to our floor plan? — Yes; send bin sizes, the number of part numbers and the line drawing — PRIMEAG draws it within 2 days.
