A vertical storage tower with an internal telescopic fork — it finds the right bin and brings it to the access port automatically. No manual racking, no aisle travel, no mis-picks.
The QDITC Vertical Sort Module Storage System works best in specific situations. Here's how to tell if yours qualifies.
Good fit：
Enter the item name and quantity — the system delivers the bin to the access port automatically. No operator travel, no manual bin searching.
Self-supporting column-and-brace frame carries all structural load — panels are cosmetic only and can be removed without affecting equipment stability. Max height 9 m, max width 6.5 m.
Max 9 m × 6.5 m · Skin-independent
8 positioning wheels per side (2 per corner), each with an eccentric axle for precision adjustment. Two sets (four) of synchronous belts — if one belt fails, three remain to hold the trolley level.
16 wheels · 4-belt redundancy
Cold-rolled steel ≥1.0 mm, Q235-B, spray-coated with sand-grain surface finish. Dust-proof and anti-theft spliced enclosure. Transparent panels at ≥1.5 m height allow direct visual inspection of trolley status.
Q235-B · Transparent inspection panels
Cold-rolled sheet brackets form the internal shelf structure. Column splices are easy to disassemble and replace — individual column segments removed and replaced without dismantling the entire assembly.
Modular column splicing
Proven fork mechanism handles single-depth and double-depth bins in both horizontal directions — compatible with circulation bins, cartons, and totes. Custom fork configurations available for non-standard geometries.
Bidirectional · Custom fork options
Motor braking
Stable trolley structure
Up/down track guidance
Optional hook straps for maintenance entry
Automatic stop at highest/lowest warning positions. Buffer blocks at travel limits.
5 independent protection layers
Non-powered fluent strip at the access port makes bin retrieval effortless. Standard configuration supports direct manual picking without additional tooling.
Non-powered fluent strip
Any object interrupting the beam during bin movement stops the system immediately. 25 mm pitch. Barrier activates only during active transit — not when the port is idle.
CE certified · EN ISO 13849
Full inventory control and equipment scheduling included. Multi-device online operation; ERP and peripheral system interface via standard API. No third-party licence required.
No additional licence fees
Vertical Sort Module Storage System Very flexible, providing a range of optional features. Adopting modular design, it can be configured according to different needs and can integrate other components at any stage (before or after installation).
For manual picking scenarios — an integrated workstation at the access port for operator-directed retrieval without system input.
For conveyor or AGV integration — an automatic docking station enables seamless handoff between the VSM and downstream automation equipment.
25 mm pitch grating measures each bin's loaded height on inbound. The system assigns the most space-efficient storage slot automatically — maximising capacity over time.
