Line-side part presentation racks are fixed structures alongside the assembly line that present components, sub-assemblies, and consumables to assemblers in ergonomic gravity-fed lanes. Rack design is driven by the operator's reach zone, the component BOM, and the takt time — every component delivered to the exact ergonomic position at the exact moment of use.
All component lanes positioned within the operator's primary reach zone — lane heights set to NIOSH recommended lift zones for each component weight class.
Lane depth calculated from takt time and replenishment frequency — delivers exactly one replenishment cycle of supply without over-stocking the line side.
Wide lower-tier lanes support cartons and tote bins; upper tiers serve smaller bins and hardware — full BOM component range in a single structure.
Lane pitch angles components toward the operator at the optimal presentation angle — reduces reach distance and wrist deviation at the pick point.
Open-frame T-slot structure with no solid panels — operators maintain sightlines across the line and into adjacent cells at all times.
Label holder extrusions on each lane face carry part numbers, bin quantities, and Kanban cards — all information at the point of consumption.
Line-side racks presenting interior trim panels, fastener bins, and clip trays to trim assembly operators — all parts within reach at takt time.
Heavy component and hardware flow lanes alongside engine assembly lines — all BOM parts at ergonomic height for long-cycle precision assembly.
Mixed large-panel and small-hardware presentation racks alongside appliance final assembly lines — all components at operator reach.
Component cartons and hardware bins presented at electronics system assembly stations — all parts in assembly sequence at operator height.
Large sub-assembly and fastener presentation racks alongside agricultural equipment final assembly lines.
Controlled-component presentation racks at aerospace sub-assembly stations — lane sequence matches build procedure step order.
Small hardware and sub-assembly flow racks at power tool assembly stations — all BOM parts within reach for high-volume cycle assembly.
Large-component and hardware flow lanes at HVAC system assembly stations — all parts at ergonomic height for manual assembly operations.
Lane depth is calculated from takt time, component consumption rate per takt, and replenishment frequency. The goal is a lane depth that holds exactly one replenishment cycle — long enough to avoid frequent replenishment stops, short enough to prevent over-stocking on the line side.
Yes. Lower tiers with wider lane spacing and roller track handle large cartons and heavy bins. Upper tiers with narrower lanes and wheel track handle small bins and hardware. A single rack structure can cover the full BOM component size range.
Standard positioning places the rack face 300–600mm from the assembly line to allow operator reach access and adequate aisle space for replenishment on the rack rear. Exact positioning is determined by the operator's reach envelope and the aisle width available.
Roller track lanes support up to 50 kg per lane for heavy cartons and large sub-assemblies. Wheel track lanes are rated to 30 kg per lane for medium-weight bins. Lane loading calculations are included in Modular Solutions engineering drawings.
Freestanding racks on levelling feet reposition with standard material handling equipment. Line-attached racks detach from line frame brackets in minutes. Full rack repositioning for line rebalancing is supported without purchasing new hardware.
Card holder extrusions mount to T-slot channels on each lane front face — one card holder per lane. Cards are visible to replenishment operators from the rack rear aisle. Two-bin divider stops are available as an option for physical two-bin Kanban on individual lanes.
