Cantilever Rack

Cantilever Rack – The Definitive Solution for Long, Bulky, or Irregular Loads

Cantilever rack is the industry’s go‑to storage system for materials that cannot be stored on standard pallet racks: pipes, lumber, steel bars, aluminium extrusions, furniture boards, plastic tubing, and even rolls of carpet or fabric. Its open‑front, arm‑based design eliminates obstructive front columns, allowing forklifts or overhead cranes to load and unload from the full length of the rack with zero interference.

Why Cantilever Rack is the Universal Standard:
No other rack type offers the same combination of unrestricted access, infinite length adjustability, and heavy load capacity for awkwardly shaped products. That is why it appears as the default name on nameplates, in BOMs (bills of materials), on quote line items, and across GA (general arrangement) drawings worldwide.

Key Structural Components (as labelled on engineering drawings):

· Upright (column): heavy‑gauge steel channel or I‑beam, base‑plate mounted to floor
· Base (horizontal arm): welded box or channel section, bolted or pinned to upright
· Arm (cantilever arm): tapered or straight profile, adjustable vertically in 50–100 mm increments
· Bracing (diagonal & horizontal): secures uprights together in a rigid frame
· Floor anchors: chemical or mechanical anchor bolts per seismic/forklift impact requirements

Technical Specifications (Typical for Export Engineering Packages):

· Column height: up to 12 m (custom beyond for special applications)
· Arm length: 300 mm to 2,500 mm (single or double sided)
· Arm load capacity: 500 kg to 4,500 kg per arm (depending on arm length and profile)
· Upright frame capacity: 5 to 25 tonnes per frame
· Material: Q235B / Q355B (or equivalent S235JR / S355JR) hot‑rolled or cold‑formed steel
· Finish: powder coated (standard RAL colours) or hot‑dip galvanised (outdoor/corrosive environments)

Configuration Options (Clearly Defined for Quotations & Drawings):

· Single‑sided cantilever rack – arms on one side of the upright, against a wall
· Double‑sided cantilever rack – arms on both sides, serving two aisles (maximum space efficiency)
· Forklift‑accessed – standard configuration for most warehouses
· Crane‑accessed – deeper arm spacing, often with reduced bracing for unobstructed top loading
· Mobile cantilever rack – mounted on rail‑guided carriages for dense storage (moving aisle system)

Advantages That Make it the First Choice (Globally):

1. Zero front obstruction – load length is virtually unlimited
2. Fast adjustability – arms reposition without tools using pull‑pins or clip‑in designs
3. High impact resistance – heavy‑duty uprights withstand forklift bumps better than roll‑formed rack
4. Clean naming – "Cantilever Rack" is understood instantly on any quote or drawing, from Houston to Hamburg to Shanghai

Common Applications (Industry‑Proven):

· Steel service centres (bars, angles, channels, pipes)
· Lumber and panel yards (plywood, MDF, OSB)
· Plastic and rubber extrusion plants
· Furniture manufacturing (board and trim storage)
· Aerospace and automotive (long composite or metal components)
· Home improvement retail (display of mouldings, conduits, gutters)

Safety & Compliance (For Engineering Sign‑Off):

· Designed to FEM 10.2.02, EN 15512, AS4084, or RMI specifications – specify which code per project
· Seismic calculations available for zones up to 0.4g PGA
· Optional column protectors, load indicator plaques, and end‑of‑arm stops
· Factory load testing certificate supplied with each system

⚠️ Engineering note: For cantilever racks exceeding 6 m height or 1.5 m arm length, a structural stamped drawing is mandatory for most building permits. We provide CAD and BIM‑ready files (DWG, Revit) as standard for export projects.

How to Specify Cantilever Rack on Your Next RFQ (Template):

· Single or double sided
· Overall length / number of bays
· Upright height (floor to top of column)
· Arm length and quantity per upright
· Arm load capacity per pair
· Floor anchoring type (anchor plan required)
· Colour (RAL code)
