窄巷道货架是仓储货架的一种，因其货架系统的叉车搬运通道相比之下较为狭窄，故名窄巷道或窄通道货架。
货架系统主体为横梁式货架系统，区别在于货架底部地面上加装“三向堆垛叉车”的行动导轨。导轨常规采用不等边角钢。物料搬运叉车限为专用的“三向堆垛叉车”。三向堆垛叉车沿既定导轨滑行。货架系统的堆垛通道宽度稍大于托盘货物的宽度，高密度的存储需求得以实现。同时继承了横梁式货架系统的所有优点，货架系统所收纳的所有物料均具备100%的可选性，叉车可随时存储任一托盘货物。快速的存储效率，非常高的存储密度，对于适合采用窄巷道货架系统的存储与物流中心来说，带来的是显著的生产效率与成本效益。
Itis designed to meet the new generation of warehouses up to 15m high, designed around the operating tolerances ofVery Narrow Aisle(VNA) equipment with aisles marginally wider than the load. Such structures must have a high level of rigidity and accurate manufacturing tolerance. Interlock is designed to meet these requirements.
Increased capacity with increased height
Warehouse capacity can be increased by an additional 40% overSelective Pallet rackingby increasing operational height and the reduction of operation aisle.
Optimal operation
Radio frequency (RF) controls on theMaterial handling(MH) equipment will ensure maximum pallet cycles per hour. A smaller reach or counterbalance is generally used in conjunction with the operation of the VNA MH machine, to maximise operation when within the aisle.
High-Bay Storage Advantages
Good stock rotation
Good order picking: 100% selectivity
Fast picking rate
Good product protection
50% net pallet area usage of overall warehouse area
Limited pallet redundancy as system can run at 95%+ capacity
Uses guide rails or wire guidance for fast movement in aisle
