Pipe is the heaviest, longest, and least forgiving thing a storage system can hold. A full bundle of 12-meter line pipe weighs more than a car and wants to roll the moment it is not restrained. It has to be lifted with a crane, stacked without damage, and retrieved without disturbing the rest of the stock — and every plant that handles it knows the cost of getting any of those steps wrong. The Herochu CE ISO certified heavy duty manual cantilever pipe rack is engineered for exactly this load class: 5,000 kg per level, 12-meter capacity, dual-side discharge, and certification that backs every rated number on the drawing.
Engineering for 5,000 kg per Level
A rack rated at 5 tons per level earns that number from the ground up. Herochu’s HC-G series starts with a frame welded from Q235B high-strength steel, the workhorse structural grade for load-bearing industrial equipment. Two design details carry the actual weight:
- Dual-beam crossbar design. Each tier is supported by twin beams running the length of the bay. The load spreads across two members instead of one, so a full bundle on one side and an empty compartment on the other does not twist the frame out of square.
- Cantilever arms rated to the tier. The arms extend 100% out of the frame on rollers, and at full extension they carry the published load — the worst case, not the empty case. That is the number the structure is calculated for.
The drive is a gear-and-rack mechanism turned by a hand crank. It is deliberately low-tech: no motors, cylinders, or accumulators to fail, and no electrical energy stored anywhere in the system. Grease it, check it, and it keeps working. Heavy-duty in this design means heavy-duty simple.
CE and ISO: What the Certificates Actually Cover
Two marks, two different guarantees, and serious buyers check both:
- CE certification confirms the rack meets the essential safety requirements of the EU Machinery Directive. The risk assessment, structural calculation, and Declaration of Conformity cover the loaded condition, the moving parts, and the operator’s exposure during use. The nameplate and paperwork make the rated capacity traceable to engineering, not to marketing.
- ISO certification confirms the production system behind the rack: qualified welding, controlled materials, documented inspection, and repeatable quality. When the rack is built in an ISO-managed facility, the certificate on the product is a statement about how it was made, not just how it performs.
Together they give a purchasing department what it needs: a structural rating that is engineered and verified, and a manufacturing process that is audited. For projects where the storage rack is specified into a tender — pipe yards, structural steel workshops, energy and shipbuilding contractors — both certificates are usually requested before the order is placed, and Herochu supplies them as standard documentation.
Handling 12-Meter Pipe Without a Wide Aisle
The reason the HC-G12065 exists is the simple geometry of long pipe: a 12 m bundle stored on the floor claims 12 m of aisle, and forklift handling of 12 m loads is slow and risky. The manual cantilever pipe rack changes the geometry:
- The pipe lies on the cantilever arms at working height, not on the floor.
- The operator cranks the tier out to full extension.
- The overhead crane hook lowers onto the exposed arms, lifts the bundle, and moves it straight to the saw, the bevelling station, or the truck.
Because material is handled by crane from above, the rack needs no forklift aisle. Rows of racks can sit close together, and the same floor area stores substantially more linear meters of pipe. Discharge works from both sides — dual-side mechanical assistance — so a rack placed against a wall, or a double unit serving two bays, never forces the crane into a corner.
Technical Parameters
| Model No. | Pipe Length | Max. Load per Level | Number of Layers |
|---|---|---|---|
| HC-G6053S | 6,000 mm | 3,000 kg | 5 (customizable) |
| HC-G6053 | 6,000 mm | 3,000 kg | 5 (customizable) |
| HC-G9065 | 9,000 mm | 5,000 kg | 6 (customizable) |
| HC-G12065 | 12,000 mm | 5,000 kg | 6 (customizable) |
Clear space: 600 mm (customizable). Material discharge method: dual-side mechanical assistance. Layer counts are standard values; every Herochu rack is built to order, with tier heights, compartment widths, and layouts customized against the buyer’s actual stock list.
Service Life and Maintenance
A manual rack has a short maintenance list, and following it keeps the unit in service for decades:
- Lubrication. Grease the gear-and-rack drive and the carriage rollers at scheduled intervals; the manual specifies the points and the grease grade.
- Visual inspection. Check the frame welds, the arm rollers, and the anchor bolts periodically, especially after the first month of full-load operation.
- Coating care. Touch up any damage to the industrial paint finish promptly so bare steel does not start corroding in a humid hall.
- Load discipline. Keep compartment loading within the nameplate rating — 3,000–5,000 kg per level depending on model — and load symmetrically where practical.
None of this requires a specialist. It is the kind of maintenance a plant’s own crew handles in a morning, which is exactly why the manual design stays popular in heavy industry: the machine that needs no electrician and no hydraulics engineer.
FAQ
What load can one level of the rack carry? 3,000 kg per level on the HC-G6053S and HC-G6053; 5,000 kg per level on the HC-G9065 and HC-G12065.
What is the longest pipe the rack can hold? 12,000 mm on the HC-G12065, with 6,000 mm and 9,000 mm options in the same series.
Do the arms really extend fully under load? Yes. The arms extend 100% of their travel, and the published per-level capacity applies at full extension.
Which certificates ship with the rack? Each unit ships with its CE Declaration of Conformity and is manufactured in an ISO-certified facility, with the documentation pack supplied as standard.
Specify the Heavy-Duty Option
If your next pipe yard or workshop layout is being designed around 5-ton bundles and 12-meter lengths, ask for the HC-G12065 and its documentation pack. Send Herochu your stock list and crane capacity, and the engineering team will return a layout, load calculations, and a quotation for a CE ISO certified heavy duty manual cantilever pipe rack that matches the tender specification.
