VNA Pallet Racking System

VNA (Very Narrow Aisle) pallet racking is a high-density adaptation of selective racking that operates in aisles of just 1.5 to 1.8 meters — compared to 3.0 to 3.6 meters for standard selective. It uses specialized turret trucks or articulated forklifts to access pallets. The key advantage is achieving up to 50% more pallet positions while maintaining 100% pallet selectivity — something that drive-in and double deep systems cannot offer.

VNA racking requires specialized material handling equipment: turret trucks (man-up or man-down), articulated forklifts, or order pickers. These vehicles have rotating fork heads that pivot left or right to place and retrieve pallets without turning the truck chassis. Popular VNA truck brands include Jungheinrich, Crown, Linde, Yale, and Toyota. We provide compatibility specifications during the design phase to ensure your truck and racking work together.

Wire-guided systems use an inductive wire embedded in the warehouse floor (typically 50mm deep). The turret truck's antenna detects the wire's magnetic field and automatically steers the truck along the center of the aisle with ±10mm accuracy. Rail-guided systems use physical steel rails bolted to the floor on both sides of each aisle to mechanically channel the truck. Wire guidance is more precise and popular; rail guidance is simpler and cheaper to install in existing facilities.

VNA typically provides 40-50% more pallet positions than standard selective racking in the same warehouse footprint. This is achieved by reducing aisle width from 3.0-3.6 meters to 1.5-1.8 meters, converting unused aisle space into productive storage. Additionally, VNA systems often reach greater heights (up to 14m vs 10-12m for selective), further increasing capacity through vertical utilization.

VNA installations require a flat, level floor — typically to FM2 (Fmin) or TR34 standard with flatness tolerance of ±2mm over 3 meters. At heights above 10 meters, stricter tolerances may be needed. For wire-guided systems, the floor must allow wire channels to be cut (50mm wide, 50mm deep). We assess your floor specifications during the design phase and recommend remediation if needed.

Yes, VNA is an excellent choice for cold storage. The 40-50% increase in pallet density means significantly less refrigerated space is needed, directly reducing energy costs. We use galvanized or epoxy-coated finishes for corrosion resistance in cold and humid environments. The wire-guided system operates reliably in temperatures from -30°C to +40°C.

Gieantech VNA racking supports up to 4,000 kg per beam level and up to 20,000 kg per bay. Maximum system height is 14 meters, depending on the turret truck model and pallet weight. Higher heights require thicker upright gauges (2.0-3.0mm) and additional top-tie bracing. Every system is engineered with a 1.5-2.0× safety factor.

In some cases, existing selective racking frames and beams can be reconfigured into a VNA layout by repositioning rows closer together and installing a guidance system. However, VNA requires tighter manufacturing tolerances (±1mm vs ±2-3mm for standard racking), so existing components must be assessed. We provide free feasibility analysis to determine if conversion is viable for your installation.

Standard MOQ is 50 bays (negotiable for larger projects or repeat customers). Lead time is 15-30 working days from design approval, including precision manufacturing with VNA-grade tolerances. Shipping time varies by destination — typically 15-35 days ocean freight. We provide detailed production schedules and tracking updates throughout the process.
