Product Overview

The CK METAL STORAGE SOLUTIONS 6 m gantry storage system combines fixed cantilever racks with a rail-mounted gantry robot for long profile storage. A typical configuration handles 6 m (19.7 ft) material with a 3,000 kg (6,600 lb) rated load per storage unit. The system suits profile processors and metal stockholders that need selected loads delivered to a defined transfer station.

6 m (19.7 ft) material length: size the carrier around the stock, including end clearance.
3,000 kg (6,600 lb) typical storage-unit rating: confirm the material and carrier weights in the quotation.
Fixed rack rows: the gantry moves between storage positions while the racks remain stationary.
Load-carrier retrieval: plan the separate handling step between the transfer station and your processing equipment.

Specifications for the 6 m fixed rack configuration

The 6 m gantry storage system is specified around your carrier loads and site layout, rather than a single standard warehouse footprint.

Group	Item	Configuration
Capacity	Material length	6 m (19.7 ft) for this configuration
Capacity	Typical rated load	3,000 kg (6,600 lb) per storage unit; rating basis defined in the project specification
Dimensions	Carrier clear length	Sized for the material and agreed end allowance
Dimensions	Carrier width and support spacing	Designed from bundle cross-section, material stiffness and actual load
Dimensions	Rack height and overall envelope	Specified in the project layout, including the gantry travel and transfer station
Operation	Storage structure	Fixed cantilever racks with a rail-mounted gantry robot
Operation	Load movement	Gantry lifting platform supports the load carrier at its ends
Controls	Inventory and system interface	WMS scope and ERP or MES connection assessed for the project
Construction	Surface finish	Powder coating; paint or galvanizing options assessed for the environment

The 3,000 kg figure is a storage-unit rating, not a rating for each individual cantilever arm. The final specification must identify whether carrier tare is included. No travel speed alone defines the number of complete retrievals per hour.

When fixed racks fit your material flow

Fixed cantilever gantry storage fits a planned long-stock area where selected carriers must reach a controlled handoff position.

Choose this configuration when your main stock is 6 m long and the proposed carrier loads fit the specified rating.
Consider fixed rows when the approved layout can accommodate permanent rack positions and the gantry movement envelope.
For aluminum profile processing, include the surface condition and handling contact requirements in the carrier review.

The configuration is unsuitable when you expect the storage robot alone to separate individual bars or feed any existing machine automatically. A separate loading interface needs assessment. A simpler crane-served rack may be appropriate when you prefer direct manual access to individual levels.

How the gantry stores and retrieves a carrier

The gantry transfers a load carrier between the station and a selected position on the fixed cantilever racks.

An operator or external handling device places the prepared load at the agreed transfer station.
The control system receives the storage instruction and identifies the destination.
The gantry approaches the carrier and lifts it using the end supports.
The gantry travels to the selected location and places the carrier on the rack supports.
For retrieval, the gantry brings the selected carrier back to the transfer station.

People must remain outside the equipment working area during operation. An aisle-entry alarm is an optional configuration. The site safety design must define access procedures and protective measures. During a power failure, manual extraction is not an operating backup.

Define the handoff before choosing the layout

The transfer station must suit the next production step, whether you prepare long profiles for sawing, drilling or milling.

A profile machining line may require individual bars, while the storage gantry delivers a carrier. Identify who removes the required material and where remaining full-length stock returns. Do not assume short remnants can use the same carrier or support arrangement.

For coated or anodized profiles, send the required surface condition and contact restrictions with your enquiry. Review carrier support and restraint against the actual section, rather than selecting a carrier by weight alone.

Allow clearance beyond the material length

The carrier needs end clearance beyond the nominal 6 m material length to reduce end contact during handling.

Our sales guidance recommends approximately 50 mm (2 in) at each end. The dimension sketch shows the material and end allowance only. Carrier clear length, frame construction and support positions remain part of the engineered design.

Compare storage and retrieval methods

Choose the retrieval method around your handling equipment, access needs and production handoff.

Option	What moves	Material access	Selection consideration
This fixed-rack gantry configuration	Gantry and carrier; rack rows stay fixed	Carrier presented at the transfer station.	Plan the permanent rack layout and carrier interface
Manual crane-served cantilever rack	Arms extend by hand crank; crane handles material	Access at the extended level	Useful when you retain an operator-led crane workflow
Motorized crane-served cantilever rack	Arms extend by motor; crane handles material	Access at the extended level	Motorized arm extension remains separate from automated carrier retrieval

We also design gantry layouts with mobile rack bases. Compare fixed and moving rack arrangements in the our gantry storage configuration overview . The operating sequence and site layout need separate assessment.

Configuration options for your stock

The carrier, rack layout and transfer arrangement are developed from your material and handling requirements.

Provide maximum and minimum stock lengths, bundle width and height, and actual material weight.
Specify the required inventory information and whether the system must exchange data with ERP or MES.
Request a review of the rail installation method and the transfer-station arrangement.
Available in RAL colours; the main rendering shows RAL 5012 / RAL 7016 rack colours. The yellow gantry remains a separate visible component.

Site preparation and installation

A fixed-rack project needs an agreed layout and foundation assessment before rail and rack installation.

Provide the column grid, lowest roof obstruction, usable floor area, access routes and proposed transfer location. Allow for the full gantry travel and load movement envelope. Rack footprint alone does not describe the occupied operating area.

Rail mounting can be surface-mounted or embedded, depending on the approved civil design. Confirm rack reactions, rail reactions, floor construction and electrical supply for the selected configuration. A floor-load value or power figure from a smaller installation is not a design value for this system.

The installation sequence includes foundation checks, setting out, rails, gantry assembly and rack installation. On-site commissioning and operator training follow the project plan.

Delivery and support

Our automation projects normally require 60–90 days, depending on project complexity, including inspection, trial assembly, commissioning and export packing.

Equipment ships in sections with manuals and installation videos. An engineer supports on-site commissioning, typically for about one week. The overall installation period is agreed separately for the site.

The standard warranty is one year, with an extension available by agreement. We provide spare wear parts with shipment and responds to after-sales enquiries within 24 hours. Structural engineering includes FEA verification, followed by pre-shipment assembly and functional testing.

CK METAL STORAGE SOLUTIONS is ISO 9001:2015 and ISO 14001:2015 certified. Profile rack designs use China utility model patents. Request the applicable product compliance documents with the configuration proposal.

Questions about this configuration

Q: Does a 6 m profile need a 6 m carrier?

A: No. We recommend approximately 50 mm (2 in) clearance at each end. The final carrier drawing must also account for frame construction and the required support arrangement.

Q: Does the 3,000 kg rating apply to each arm?

A: No. The typical 3,000 kg (6,600 lb) rating applies to the storage unit. The final quotation defines the load basis, including how carrier tare is treated.

Q: Can the rails sit above the existing floor?

A: Yes. Surface-mounted and embedded rail arrangements are available. The mounting method depends on the floor assessment and the agreed installation design.

Q: Can the gantry feed individual profiles into my saw?

A: That requires a separate interface assessment. Carrier retrieval does not by itself include single-bar separation or direct machine loading. Send the saw or machining-centre details with your enquiry.

Q: Can the storage system exchange data with our ERP?

A: Yes, subject to assessment of your system. We evaluate ERP or MES connections for each project, including the required inventory fields and transfer process.

Q: Can I retrieve material manually during a power failure?

A: No. Manual extraction is not an operating backup for the automated system. Access and recovery must follow the agreed procedures.

Q: Do you supply a standard footprint and electrical demand?

A: No single value applies to every 6 m configuration. Carrier dimensions, storage quantity, rack layout and handling requirements determine the project design.
