Technical Solution
A heavy-duty storage system for long aluminium extrusions and bundled profiles, designed to keep stock separated, reachable, and ready for crane-assisted picking.

What Rainbow Aluminium Needs to Solve
Aluminium extrusions are long, easy to mark, and awkward to retrieve when mixed with bundles of different lengths. Floor stacking wastes aisle space, slows picking, and increases the chance of bending or surface damage during handling.
How the Terack System Works
Independent retractable bays
Each storage layer can extend or retract on its own, so operators only move the row they need instead of shifting the full stock pile.
Roller-supported steel arms
The moving arms ride on support wheels and connect to the transmission frame, giving the rack a controlled sliding motion for heavy long-stock handling.
Modular carbon steel frame
Upright columns, fixed layers, and the drive frame are built as a heavy-duty welded structure with adjustable layer height for changing stock mixes.

Why the Workshop Layout Matters
The installed rack keeps long stock in a clear, reachable lane while leaving room for crane access and routine picking. The visible pivot joints, roller links, and layer hardware show that the system is built for repeated movement, not just static storage.
Risk Control and Maintenance
Prevent overload and arm deflection
Match the bay layout to the actual extrusion weight and length, and keep the load centered so the telescopic arms stay within a safe working range.
Inspect moving parts on a fixed schedule
Check the support wheels, linkage points, and crank drive regularly, then keep the sliding surfaces clean and lubricated for smooth operation.
