Selecting a heavy-duty cantilever pipe rack comes down to two questions that warehouse managers ask before anything else: how long are the bundles I store, and how much does each one weigh? Everything else — tier count, aisle width, drive configuration — follows from those two answers. A rack specified for six-meter, three-ton packs will not safely hold twelve-meter, five-ton loads, and a twelve-meter frame built for heavy structural sections is more steel than a light-tube operation needs to pay for.
Herochu builds the HC-G telescopic cantilever series in three core models that map directly onto the stock lengths and load ratings that dominate steel distribution and fabrication. Understanding where each model sits in that matrix is the difference between a rack that matches your operation and one that constrains it.
The Three Herochu HC-G Models at a Glance
The HC-G family is defined by three parameters: stock length capacity, per-level load rating, and standard tier count. These are the models that cover the majority of pipe, tube, and bar storage applications.
| Model | Stock Length Capacity | Load Rating (Per Level) | Standard Tier Count |
|---|---|---|---|
| HC-G6053 / HC-G6053S | 6,000 mm (6 m) | 3,000 kg (3 Tons) | 5 Layers (Customizable) |
| HC-G9065 | 9,000 mm (9 m) | 5,000 kg (5 Tons) | 6 Layers (Customizable) |
| HC-G12065 | 12,000 mm (12 m) | 5,000 kg (5 Tons) | 6 Layers (Customizable) |
The model numbers are not arbitrary — the digits encode the frame geometry. HC-G6053 handles six-meter stock at three tons per level across five tiers. HC-G12065 stretches to twelve meters and holds five tons per level across six tiers. The progression is deliberate: as stock length grows, so does the structural mass required to keep long bundles rigid and the arm carriages tracking true.
HC-G6053: The Six-Meter Workhorse for Standard Pipe Packs
Six meters is the standard mill length for round steel tubes, square hollow sections, and most commercial pipe grades. A service center or fabrication shop that handles these packs as inbound material will find the HC-G6053 sized exactly to the job. The three-ton-per-level rating accommodates a full mill pack of medium-diameter pipe — the kind of bundle that arrives banded in steel strapping and weighs between one and three tons depending on diameter and wall thickness.
Five tiers give a starting configuration that stacks five such packs in the same floor footprint that ground stacking would allocate to one. For operations that need more vertical layers — a tall warehouse bay with a high-capacity overhead crane — Herochu customizes the tier count upward. For a lower-clearance building or a lighter inventory mix, fewer tiers keep the working height within ergonomic crane reach. The HC-G6053S variant preserves the same length and capacity but packages the frame for sites where the footprint or column spacing differs from the standard layout.
HC-G12065: The Twelve-Meter Frame for Long and Heavy Stock
When the inventory includes twelve-meter packs — long seamless tubes for structural projects, large-diameter line pipe, or heavy wall casing — the HC-G12065 is the model that carries them safely. Twelve-meter bundles place extreme demands on a rack: the overhang beyond the arms must be controlled, the arms must resist the bending moment of a long, heavy pack cantilevered into the aisle, and the dual-beam structure must prevent the sag that would let a five-ton pack bow between support points.
Herochu rates the HC-G12065 at 5,000 kilograms per level across six tiers. That capacity reflects the dual-beam Q235B crossbar construction and the dual-side mechanical drive that keeps long bundles square during extension. The frame footprint is wider, the columns are heavier, and the arm carriages are engineered for the longer extension stroke that twelve-meter stock demands. This is the rack a steel distributor needs when the inventory includes oil and gas line pipe, structural I-beams, or large-format structural tubes that arrive in full twelve-meter lengths and cannot be cut down for storage.
HC-G9065: The Nine-Meter Intermediate
Between the six-meter workhorse and the twelve-meter heavy frame sits the HC-G9065, rated for nine-meter stock at five tons per level. This model serves operations that handle a mix of standard and long material — a distributor who stocks both six-meter commercial pipe and nine-meter structural sections, for instance, and wants a single rack family that accommodates both without under-loading a twelve-meter frame or over-stressing a six-meter one.
The five-ton per-level rating matches the HC-G12065, meaning the HC-G9065 handles heavy packs without the full twelve-meter frame investment. Six tiers give the same vertical density as the long-stock model. For a warehouse whose stock mix is migrating toward longer lengths but has not yet committed to full twelve-meter handling, the HC-G9065 is the bridge model that protects that investment.
How to Match the Model to Your Operation
The selection logic is straightforward. Measure the longest standard pack length in your inventory — not the occasional outlier, but the length that represents the bulk of what you store. That sets the frame: six meters selects the HC-G6053, nine meters the HC-G9065, twelve meters the HC-G12065. Then weigh your heaviest typical bundle, including the banding and any dunnage. Three-ton packs map to the HC-G6053 rating; five-ton packs require the HC-G9065 or HC-G12065.
A common mistake is to oversize the rack for a stock length that represents a small fraction of inventory. A warehouse that stores ninety percent six-meter pipe and ten percent twelve-meter special orders does not need a twelve-meter frame for the full inventory — it needs an HC-G6053 for the bulk and a dedicated long-length bay for the remainder. Herochu builds each model to standard capacities but configures tier count, compartment layout, and drive type to the site, so the rack fits the operation rather than forcing the operation to fit the rack.
Drive Configuration and Tier Customization
Within each model, two drive configurations are available. The manual hand-crank series uses a floor-level mechanical transmission that holds positive locking power without electrical supply — the configuration for unpowered halls or operations that need outage resilience. The motor-driven electric series automates extension with a single-button control and a dedicated motor per level, allowing one tier to extend independently while the others stay retracted.
Tier count is customizable across all three models. A warehouse with a twelve-meter ceiling can add tiers to the HC-G12065 and store six packs of long pipe in a single column. A building with a seven-meter eave height reduces tiers on the HC-G6053 to keep the top bundle within crane hook reach. The model sets the length and load; the configuration sets the height and drive. Together they define a heavy-duty cantilever pipe rack matched to the stock you actually carry, not a generic frame you adapt to.
