| System Definition |
Motorized or mechanically assisted shelving mounted on movable bases, with controlled access aisles. |
One or more movable rows can share a smaller number of access aisles than fixed shelving. |
Request a scaled layout showing closed and fully open positions, aisle access, emergency exits, and service clearances. |
Confirms that the proposed system is genuinely mobile shelving rather than conventional fixed shelving. |
| Storage-Density Target |
Comparison with the existing fixed-shelving layout using the same room area, shelf height, load type, and access requirements. |
Common project claims range from 20% to 80% more usable storage density; the actual result depends on the baseline layout. |
Compare usable shelf length or pallet positions per square metre before and after installation. |
“Up to 80% more” is a potential planning outcome, not a guaranteed result for every room or product category. |
| Aisle Reduction |
Number of permanently open aisles required for daily operation and emergency access. |
A 50% reduction in permanently open aisles may be achievable where multiple fixed aisles are consolidated into fewer movable access aisles. |
Check the aisle count on the complete floor plan and confirm that operational and fire-safety routes remain compliant. |
Fewer aisles can release floor area for storage, but safety routes must never be removed without approval. |
| Load Capacity |
Rated load per shelf, bay, carriage, and total moving base, including evenly distributed and point loads. |
Light-duty shelving is often rated below 150 kg per shelf; heavy-duty systems can exceed 500 kg per shelf. Ratings vary by design. |
Require stamped load tables, structural calculations, test records, and a clearly stated safety factor. |
Overloading can deform shelves, overload drive components, and create serious operational hazards. |
| Aisle Width |
Clear operating width for staff, carts, forklifts, stored materials, and emergency access. |
Personnel aisles are commonly planned around 900–1,200 mm; equipment aisles may require substantially more. |
Verify the proposed width against the handling equipment, local building regulations, fire code, and accessibility requirements. |
Aisle width directly affects safety, picking speed, equipment compatibility, and the final storage-density calculation. |
| Drive and Control |
Drive motor, gearbox, variable-speed control, manual override, soft start and stop, and aisle selection controls. |
Variable-speed drives and soft stopping help reduce mechanical shock and product movement. |
Request a live demonstration with the intended maximum load and review the control-system documentation. |
Reliable movement improves access time, reduces wear, and helps protect stored materials. |
| Safety Protection |
Presence sensors, emergency-stop buttons, obstruction detection, anti-collision protection, end stops, and overload protection. |
Emergency-stop controls should be accessible from operating positions; sensor coverage must protect the complete moving aisle. |
Perform a documented safety test under empty and loaded conditions before acceptance. |
Safety functions are essential because the system creates powered moving zones and changing access aisles. |
| Floor and Installation |
Floor flatness, load-bearing capacity, anchoring, power supply, drainage, and installation tolerances. |
The building floor must support both static storage loads and concentrated wheel or rail loads. |
Obtain a floor survey and structural review before final design; do not rely only on nominal slab thickness. |
Uneven or insufficient flooring can cause alignment problems, noise, uneven loading, and premature wear. |
| Environmental Suitability |
Temperature, humidity, dust, corrosion risk, clean-room requirements, and fire-protection conditions. |
Standard indoor systems are not automatically suitable for cold storage, high humidity, corrosive areas, or clean rooms. |
Match the materials, coatings, electrical protection, seals, and fire strategy to the operating environment. |
Environmental mismatch can shorten service life and invalidate performance or warranty conditions. |
| Energy and Operation |
Motor power, standby consumption, access frequency, control logic, and manual operating capability during power loss. |
Energy use depends on carriage mass, travel distance, load, acceleration, and daily movement cycles. |
Ask for measured energy data under a defined duty cycle instead of relying on a generic annual estimate. |
Operating data helps calculate total cost of ownership and supports energy-management goals. |
| Serviceability |
Availability of spare parts, preventive-maintenance schedule, fault diagnostics, response time, and technician coverage. |
A written preventive-maintenance plan should cover drives, chains or belts, sensors, brakes, controls, and structural fasteners. |
Review the service agreement, spare-parts list, training plan, and documented response times. |
Fast recovery is important because one inaccessible aisle can affect a large portion of the stored inventory. |
| Total Cost of Ownership |
Equipment price, installation, civil work, electrical work, software, training, maintenance, energy, and future expansion. |
The lowest purchase price does not necessarily provide the lowest cost per usable storage position. |
Compare quotations using the same capacity, shelf dimensions, load rating, safety scope, warranty, and lifecycle assumptions. |
A normalized comparison prevents hidden exclusions from distorting supplier selection. |
| Supplier Qualification |
Relevant project experience, technical documentation, quality controls, testing procedures, delivery capability, and after-sales support. |
A qualified supplier should provide layout drawings, load calculations, risk assessments, manuals, inspection records, and commissioning documents. |
Request comparable project references without evaluating a proposal solely on product price. |
Documentation and support capability are strong indicators of installation quality and long-term reliability. |
