Very Narrow Aisle Racking System: Can You Double Warehouse Capacity Without Compromising Pallet Selectivity?

VNA aisle widths range typically between 1,500 mm and 1,900 mm. The precise dimension is determined by adding the load width (e.g., a 1,200 mm pallet) to the specific clearance margin (typically 100 mm on each side) required by your turret truck manufacturer (such as Linde, Jungheinrich, Crown, or Toyota). Our structural engineers calibrate layouts down to the millimeter to prevent vehicle scrapes while eliminating wasted space.

At lift heights of 14 to 17 meters, a ground floor variation of only 2 mm between the left and right wheel tracks causes the truck mast to lean sideways by over 30 to 40 mm. This can cause the mast to strike the racking steel, damage pallets, or trigger automatic sensor shutoffs. We conduct comprehensive floor surveys and recommend laser grinding where needed before installation begins.

Mechanical steel guide rails (usually 100x75x6 mm angles anchored to the floor) offer physical fail-safe protection and prevent chassis collisions with lower uprights, making them ideal for heavy industrial sites. Inductive wire guidance embeds a low-voltage transmission wire flush into a shallow concrete slot, permitting smooth cross-aisle travel and easier floor cleaning, but requires strict sensor calibration on all MHE fleets.

Every My Interack VNA installation undergoes rigorous structural engineering modeling based on FEM 10.2.02, EN 15512, and Malaysian UBBL standards. We calculate wind, seismic, dead, and live dynamic load combinations, incorporating heavy baseplates, torque-calibrated high-tensile anchors, and reinforced portal frame cross-ties spanning aisle crowns.

Yes, provided the upright frames have adequate steel gauge thickness, height-to-depth structural ratios, and load capacities. The layout can be repositioned with condensed aisle spacing, topped with portal bracing ties, and fitted with floor guide rails. My Interack's 18000 Series Interservice team inspects your existing components to confirm if re-engineering is viable.

Yes. Beyond Malaysia, we regularly engineer, ship, and erect turnkey warehouse racking systems in Singapore, Indonesia, and across Southeast Asia. Our dedicated in-house installation crew handles customs coordination, site delivery, laser leveling, structural anchoring, and formal safety certification sign-off.
