Electric Telescopic Cantilever Rack for Long Loads: Efficient and Safe Storage for Metal Tubes and Bars

Storing long loads such as metal tubes and bars can be a significant challenge for many businesses. These materials are often heavy, bulky, and difficult to maneuver, leading to inefficient storage practices, wasted space, and increased risk of accidents. The Electric Telescopic Cantilever Rack for Long Loads is specifically designed to address these challenges, offering an efficient, safe, and high-capacity storage solution that is perfect for metal tubes, bars, and other long materials.

Powered by an electric drive system, this telescopic cantilever rack eliminates the need for manual operation, making it easy to load and unload even the heaviest long loads. The electric drive system is paired with high-precision ball bearing guide rails, ensuring smooth and precise movement of the telescopic arms. This allows for effortless extension and retraction of the arms, enabling quick and efficient access to stored materials. Whether you’re using a crane or a forklift to handle your materials, the electric telescopic arms make the process seamless, reducing labor costs and improving productivity.

Safety is a critical consideration when storing heavy long loads, and this electric rack system is packed with safety features to ensure a secure working environment. The sliding-type guide rail is equipped with a foot rolling protection device, which prevents the telescopic arms from accidentally sliding down or overturning. This feature is essential when the arms are extended, as it eliminates the risk of materials falling and causing injury or damage. Additionally, the rack system is built with precise welding techniques, thickened columns, and a scientific force-bearing structural design—ensuring that it remains stable and secure even under maximum load.

Constructed from high-strength carbon steel, the Electric Telescopic Cantilever Rack is built to withstand the demands of industrial use. Carbon steel is known for its exceptional strength and durability, making it the perfect material for a rack system that needs to handle heavy loads. Each layer of the rack can support up to 5 tons per side, with an overall maximum load capacity of 100,000kg—making it suitable for storing even the heaviest metal tubes and bars. The surface of the rack is powder-coated, providing excellent resistance to corrosion, rust, and wear. This powder coating ensures that the rack can withstand the harsh conditions of industrial warehouses, including exposure to moisture, dust, and chemicals, extending its service life.

Versatility is a key feature of this electric telescopic cantilever rack. It is available in multiple layer configurations (3-layer, 4-layer, and 5-layer) and layer lengths (6m, 9m, and 12m), allowing you to customize the rack to fit your specific storage needs and warehouse space. The color of the rack can also be customized to match your warehouse’s aesthetic or branding. For businesses that handle a variety of long materials, including different sizes of metal tubes and bars, this versatility makes the rack system an ideal choice.

The structure of the Electric Telescopic Cantilever Rack is designed for maximum efficiency and stability. The overall structure consists of column pieces, fixed arms, movable arms, stabilizing rods, transmission rods, and control end kits. Multiple sets of column pieces and stabilizing rods form the frame structure, providing a solid foundation for the entire system. The fixed arm and movable arm are assembled on each column piece, with multiple movable arm groups forming a bracket structure that is specifically designed for storing long materials. The electric drive system transmits power from the sprocket chain to the movable arm through the transmission rod, which is then converted into a gear rack transmission to enable the arm to extend outside the cargo position. This design allows for vertical storage and retrieval operations, maximizing the use of vertical space and improving storage density.

Frequently Asked Questions – Herochu Sheet Metal & Pipe Storage Solutions

Below are answers to common questions from customers exploring our industrial storage systems for sheet metal, bars, tubes, and profiles. If you don’t see your question here, feel free to reach out—we’re happy to help.


Q1: Can I customize the size, capacity, or finish of the racks?
Yes. Every Herochu storage system is built to order. Whether you need a specific height to fit under a mezzanine, a non-standard drawer depth for oversized panels, or a particular powder-coated color to match your facility’s safety coding, we’ll work with you at no extra design cost. Just share your space constraints and material specs, and we’ll engineer a solution that fits.


Q2: Are you the actual manufacturer?
We are—not a reseller or trading company. Herochu operates its own 10,000-square-meter production facility in Jinan, China, and has been designing and building industrial storage equipment for over 15 years. This allows us to control quality, lead times, and pricing directly.


Q3: Is there a minimum order requirement?
No minimums. Whether you need one automated vertical rack for a small workshop or a full warehouse rollout with multiple units, we accommodate all project scales. Single-unit orders receive the same engineering attention and quality checks as large-volume contracts.


Q4: How can I access detailed technical information?
Click the “Get a Quote” button on our website to request CAD drawings, load capacity charts, installation manuals, product videos, and 3D renderings. Our sales engineers will also schedule a call to walk you through specifications based on your application—no generic brochures, just relevant details.


Q5: What information do you need to design a storage solution for me?
To create an accurate proposal, please provide:

  • The type of material (e.g., steel sheet, aluminum extrusion, stainless tube)
  • Dimensions (length, width, thickness/diameter)
  • Weight per bundle or individual piece
  • Desired storage density (how much you need to store in a given area)
  • Any automation requirements (e.g., integration with laser cutters or CNC machines)

You can also simply leave your contact info, and a specialist will reach out to guide you through the process.


Q6: Do you offer automation like robotic arms or gantry loaders?
Yes. We design and integrate servo-driven gantry systems, loading robotic arms, and automated material exchange platforms that sync with your existing machinery—especially laser cutting tables. These systems can pull sheets or profiles directly from our vertical racks and place them onto your machine bed, reducing manual handling and cycle time. Tell us your equipment model and workflow, and we’ll tailor the interface.


Q7: Do you provide on-site installation support?
Absolutely. Our certified technicians travel internationally to handle assembly, calibration, and operator training. We’ve completed installations across North America, the Middle East, Africa, and Asia—including the USA, Mexico, South Korea, Russia, Qatar, Egypt, South Africa, and Lebanon. Remote support is also available for simpler setups.


Q8: How do you guarantee product reliability and safety?
Quality isn’t an afterthought—it’s built into every stage:

  • All structural components use Q235 or higher-grade steel, welded and stress-tested.
  • Every unit undergoes full-load simulation before shipping.
  • Our in-house quality control team follows ISO 9001 protocols from raw material inspection to final packaging.
  • All export units carry CE certification, meeting EU mechanical safety standards.
  • Over 40 experienced engineers support design validation, troubleshooting, and continuous improvement.

Q9: Where is your factory located?
Our manufacturing base is in Jiyang Industrial Park, Jinan, Shandong Province, China. The facility spans 10,000 square meters and includes dedicated zones for cutting, welding, surface treatment, assembly, and testing. We welcome both virtual and in-person visits so you can see our capabilities firsthand.
