Herochu Heavy-Duty Cantilever Storage Racks – Built for Australian Steel, Concrete & Time-Pressure
From AUD $3,660 | CE-UE-ISO 9001 | 3 t – 5 t per layer | 6 m – 12 m arms | Manual or Electric | Custom colours & cyclone-rated footplates
If you store 9 m railway rail, 300 mm aluminium billet or 12 m hardwood glulam on the ground, you already own the most expensive shelving in the world—your floor. Herochu’s HC-G cantilever range turns that dead floor into vertical dollars: up to 5 tonne per layer, 100 % roll-out access, and a footprint slimmer than a pallet rack aisle. Designed for Australian workshops, the racks are pre-galvanised inside and out, cyclone-anchor ready, and shipped as flat-pack kits that two blokes and a ute can erect between smoko and lunch.

Need 7.5 m arms to match your plasma bed? Want 8 levels because the roof is 8.5 m high? Tell us the heaviest bundle and the crane hook height; we will recut the uprights, reset the arm spacing and still keep the price locked at the day of order. Manual pin-lock arms for hand-loaded tubing? Done. 415 V electric rollout so your overhead crane can drop 5 tonne of RHS straight onto the saw in-feed? Also done.
Why cantilever beats block stacking—especially in Australia
- Fire code: the new Australian Standard AS 4084-2023 requires 600 mm flue space between stockpiles if you store combustible pallets. Cantilever arms create natural flue gaps, so the inspector signs off without you restacking half the yard.
- Cyclone ratings: our footplates are 12 mm folded plate with 26 mm anchor holes, tested to 1.5 kN uplift in Darwin wind region C.
- Corrosion: 275 g/m² hot-dip gal inside the tube before fabrication, then 80 µm marine-grade powder coat on exposed edges—Brisbane humidity or Karrara salt spray, the arms won’t bloom white rust.
- Space: double-sided units need only 3.34 m width; a forklift aisle of 3.8 m satisfies AS 2359. That is 40 % less real estate than traditional selective pallet rack.
Roll-out arms = crane-friendly arms
Each arm is a 200 × 80 × 6 mm RHS backbone welded to a 20 mm pinion shaft. Pull the spring-loaded handle and the arm glides out on sealed bearings, giving 100 % extension even under 5 tonne. Your overhead crane can lower a bundle directly onto the arm, then retract it—no walking on loose timber, no manual pry-bars. When the job changes, the same arm accepts timber packs, PVC conduit or 12 m scaffold tube; the replaceable UHMW strips stop galvanic corrosion between aluminium and steel.
Pin-lock vs bolt-on: choose once, regret never
Medium- and heavy-duty arms lock into 75 mm pitched slots with a 25 mm hardened pin. Impact from a 3 tonne load actually tightens the wedge; the arm gets stronger, not looser. If you re-profile tomorrow, bang out the pin, move the arm, job done—no torque wrench, no thread seize, no downtime. Light-duty levels still use bolts for cost-sensitive hand-loading zones; we supply M16 8.8 zinc-flake bolts pre-dipped in anti-seize so you don’t curse the next bloke.
Electric rollout option—no chains, no drama
Fit a 0.75 kW SEW braked motor to each upright. Push-button on a pendant moves all arms in that tower simultaneously at 40 mm/s, soft-start so the load doesn’t bounce. Limit switches auto-stop at full extension and retraction. If the crane operator is busy, the storeman can pre-extend the arm from the ground, walk away, and pick later. Power is 415 V 3-phase common on every Australian site; single-phase 240 V inverter available for rural sheds.
Starter vs add-on: grow like Lego
Every order begins with a starter bay—two uprights plus arms. After that you clip on add-on bays sharing the common upright, so you pay for one less column each time. Whether you need 6 m or 60 m of continuous rack, the price scales linearly and the footings repeat every second bay. If you relocate, unbolt, stack on a flat-bed, and reinstall the same afternoon—no proprietary parts to hunt for.
Real Australian numbers
- Perth structural steel fabricator: replaced ground stacking with 5 × HC-G12055D, gained 1,850 m² floor back, rented it to a neighbour for AUD 185 k/year.
- Adelaide irrigation pipe reseller: 9 m single-sided racks, 6 levels, 320 SKU of poly pipe picked by crane, cut order prep time from 45 min to 8 min.
- Townsville mine workshop: cyclone-rated footplates passed 1 in 500-year wind load, racks survived Cat-4 cyclone with zero deflection.
Safety extras that cost less than one lost-time injury
- Drop-pin safety clips: bright-orange PVC, impossible to “forget”.
- Arm stoppers: 100 mm high, removable, stop round bar from escaping when the crane jerks.
- Down-aisle protection: 5 mm rubber facing on first upright 600 mm high—forklift glances off instead of creasing steel.
- Load plaques: laser-etched stainless, not stickers that peel in the sun.
- Annual inspection checklist: we email a PDF and a QR code that opens a one-page form; tick, photo, upload, done.
Delivery & duty-smashed pricing
Racks leave our Qingdao plant every Friday, land in Sydney, Melbourne, Brisbane or Fremantle 18 days later. We pre-pay import duty and GST, so the price we quote is the price you pay—no surprise bills from customs. Flat-pack means 22 tonne fits in one 40 HC, cutting freight per kg by 38 %.
