Herochu Long-Span Racks—Built by Jinan Constant Storage Machinery for Plants That Treat Floor Space Like Real Estate
When a single 9 m stainless tube costs more than the forklift that moves it, storage stops being an after-thought and becomes balance-sheet strategy. Herochu—manufactured by Jinan Constant Storage Machinery Co., Ltd.—designs long-span racks for companies that refuse to finance bent profiles, scratched extrusions or the lost hours spent fishing a bar from the back of a 4 m deep stack. Starting at USD 3 698 for a four-layer power-assisted bay, every frame is CE-, EU- and ISO 9001-certified and ships with a calculated floor-loading diagram signed off by a licensed structural engineer.
Who We Are, Why It Matters
Jinan Constant Storage is not a trading desk that rebadges import containers. We cast, cut, weld, machine, paint and assemble in our own 42 000 m² plant outside Jinan. The same technicians who programme the fibre lasers also sign the inspection reports, so when we quote 3 t or 5 t per layer we speak from test certificates, not wishful thinking. That vertical integration is why we can customise beam spacing, arm length, load rating or motor voltage in 10–12 working days without surcharges.
The Range—Four Reference Models, Infinite Variations
HC-G6053S – 6 m single-side, 3 t per arm, 4 + 1 layers, manual or 24 V power-assist
HC-G6053D – 6 m double-side, 3 t per arm, 4 + 1 layers, arms extend from both faces for crane access
HC-G9055S – 9 m single-side, 5 t per arm, 4 + 1 layers, ideal for 40 ft structural sections
HC-G9055D – 9 m double-side, 3 t per arm, 4 + 1 layers, highest density for tube stock
All dimensions—column height, arm pitch, base width—are nominal. We recut arms to 5 832 mm if your aluminium extrusions are 5 800 mm and we space columns at 1 492 mm if your overhead crane hook demands it. The price remains USD 3 698 for the first bay because modularity is engineered into the beam punching, not added as a luxury.
Steel Specification That Outlives the Building
Columns: 360 × 90 × 6 mm hot-rolled I-beam, S355 grade, yield 355 N/mm²
Arms: 200 × 100 × 5 mm rectangular hollow section, internal diaphragms welded every 450 mm
Base: 12 mm plate with six M24 anchor slots, tested to 120 kN shear in C30 concrete
Finish: two-coat epoxy zinc-rich primer + polyester top-coat, 130 µm total, salt-spray 1 000 h
The arm deflection limit is L/300 under safe working load; at 5 t the tip of a 1 500 mm arm moves <0.5 mm—below the threshold that causes bundle shift when the crane releases.
Power-Assisted Movement—One Finger, Five Tonnes
Each arm rides on two sealed bearings running on induction-hardened 45# steel rails. A 24 V brushless gear-motor drives through a self-locking worm reducer; crank force drops from 45 kg to 3 kg. Should power fail, a hex socket in the motor housing accepts a standard hand crank—no back-driving, no runaway. Limit switches stop extension at 92 % to prevent accidental tip-off and retraction at 0 % to protect toes. The entire drive unit is IP54; replace it in 15 minutes with two spanners.
Safety Credentials That Insurers Accept Without Argument
Triple anti-tip rails lock the load even if the crane operator shocks the bundle. A photoelectric grille across the aisle disables motor movement while personnel are inside the bay. Orange LED line lasers project a 2 m warning footprint on the floor whenever an arm is extended. These are not catalogue extras; they are included because we have learned that the cheapest insurance premium is the one you never claim.
Real-World Footprints—From Workshop to Shipyard
Metal service centre, Rotterdam: six HC-G9055D bays store 192 t of 12 m stainless pipe. Crane picks dropped from 22 to 5 per shift; floor space saved 210 m², now leased to a neighbouring fabricator for EUR 28 000/year.
Timber mill, Vancouver: HC-G6053S racks with 800 mm arms hold 6 m glulam beams. Arm tilt adjusted to 4° prevents roll-off; retrieval time cut 68 %.
Oil-rig yard, UAE: custom 12 m double-side units with 5 t arms withstand 65 °C ambient. Epoxy top-coat modified with UV blocker; no colour fade after 4 000 h exposure.
Scalability Written Into the Steel
Columns are punched on 50 mm pitch down the entire length. Add a mezzanine, bolt on extra arms, swap manual for powered drives—no hot work, no repaint. We keep replacement arms, motors and rail sections in stock for 15 years; next-day despatch to any port. Your first bay talks to the last bay because the hole pattern never changes.
Ordering Process—Engineers Talk to Engineers
- Email the longest, heaviest and most frequently handled item—drawing or photo.
- We return a CAD plan, load diagram, anchor map and freight quote within 24 h.
- Confirm; 30 % deposit starts fabrication. Balance on B/L copy.
- Rack ships knocked-down in export-grade plywood crates; four bays fit a 20 ft container.
- Two technicians supervise installation and load-test with your crane operator; hand-over certificate includes CE declaration, torque log and maintenance schedule.
Optional Upgrades—Priced by the Metre, Not by Mystery
- Weigh cells ±2 kg accuracy, RS485 to ERP
- Hot-dip galvanised finish for outdoor pipe yards
- Servo traverse system—arm moves 300 mm left/right for ±5 mm placement accuracy
- RFID arm tags for automatic inventory reconciliation
Long-span racks are no longer a commodity; they are a production tool. Herochu, manufactured by Jinan Constant Storage Machinery, delivers the strength, precision and expandability that let you quote faster because you know exactly where every metre of material is, undamaged and ready for the next cut.
