Storing long profiles is not difficult. Storing them so that a specific 8-meter bar can be retrieved in under two minutes, without climbing, dragging, or moving a second bundle, is where most rack systems fall short. The electric telescopic cantilever rack solves the retrieval problem by turning deep storage into aisle-side presentation.
Herochu builds these systems for factories, steel service centers, and construction-material warehouses that handle pipes, tubes, aluminum extrusions, stainless bars, and irregular long stock. The design principle is simple: no operator should reach into a rack, and no crane should have to fish material out from between columns.
Telescopic Arms and the End of Deep-Reach Storage
A fixed cantilever arm requires the operator or crane to reach into the rack structure. The deeper the rack, the harder the retrieval. A telescopic arm extends outward from the column, presenting the load at the aisle edge. Herochu’s arms extend 600 millimeters beyond the carriage frame and can swing out 90 degrees, converting a deep storage pocket into an accessible shelf.
The movement is powered. A single-side or double-side assisted electric drive moves the tier smoothly, and the operator controls it from the aisle. For heavy bundles — Herochu systems handle single-layer loads of 3 to 8 tonnes — the electric drive removes the physical effort that manual crank systems demand on every pick. One operator can pick or replenish an 8-tonne bundle in under two minutes, without a second person guiding the load or a forklift repositioning the rack.
One Aisle, 100 Percent Selectivity
Traditional cantilever layouts multiply aisles as storage rows increase. Herochu’s rail-type telescopic design shares a single ground rail between rows, so only one aisle is required for simultaneous loading and unloading. The rail is chemically anchored to the slab, which keeps the structure stable under lateral loads from cranes or high-bay forklifts.
The practical result is high-density storage without the honeycombing that plagues static racks. Every tier is accessible 100 percent of the time. A bottom tier holding 2-inch OD tubing can be extended without disturbing the 4-inch OD tubing stored above it. For a warehouse carrying multiple alloys, wall thicknesses, or profile geometries, that selectivity is the difference between a storage system that supports production and one that slows it down.
Built Around the Material, Not a Catalog Size
Long stock is not uniform. A rack that handles 6-meter PVC pipe may not be configured correctly for 12-meter stainless bars or bundled aluminum profiles. Herochu engineers review the inventory mix, crane hook path, forklift type, and local seismic requirements before setting column spacing, arm projection, and load rating.
The company’s electric telescopic cantilever racks carry CE, UE, and ISO 9001 certification, with traceability on welds and motors. Optional surface protection includes PVC or stainless-steel sleeves for polished bars, and integrated weighing cells can feed real-time stock data to a warehouse management system. For outdoor yards, a hot-dip galvanized finish is available; for chemical plants, explosion-proof motors can be specified.
The Space Arithmetic
A 36-meter-long, 4-meter-high system with six cantilever levels can store 720 tonnes of steel pipe in 144 square meters. That represents an 80 percent space saving compared with selective pallet racking in the same footprint. The saving comes from vertical density and the shared-aisle rail design, not from squeezing the operator into an unsafe gap.
For operations that need to move the rack itself, Herochu also offers an electric mobile base. A 0.75 kW gear motor moves a fully loaded rack at 6 meters per minute, with soft-start and photoelectric sensors for collision-free travel. Push-button or remote control opens only the aisle that is needed, shrinking the access footprint to 2.5 meters regardless of system length.
Where Electric Telescopic Storage Pays Off
The strongest fit is a production environment where long material is picked by specification, not by bundle. A fabrication shop cutting tubes for a weldment, a service center filling an order for a specific alloy, or a machinery builder pulling a drive shaft or hydraulic cylinder — these operations lose time every shift to secondary handling. An electric telescopic rack removes that handling from the workflow without requiring the operator to climb the rack or wait for a forklift.
Herochu configures each system around the actual long goods in the building. The question is not whether the rack looks compact on a drawing; it is whether the correct profile reaches the machine or the shipping bay without a second move. That is the metric an electric telescopic cantilever rack is designed to improve.
