6 Features of Very Narrow Aisle Racking Systems (VNA)The very narrow aisle racking system is also called the VNA racking system, because the forklift handling aisle of the racking system is relatively narrow, hence the name VNA racking system.The main body of the VNA racking system is a pallet racking system, and the action rails of "three-way stacking forklift" are installed on the bottom of the rack. The guide rails are conventionally made of unequal angle steel. Material handling forklifts are limited to dedicated "three-way stacker forklifts". The three-way stacker forklift slides along the established guide rails.The stacking channel width of the VNA racking system is slightly larger than the width of the palletized goods, and the high-density storage requirements can be fulfilled. At the same time, it inherits all the advantages of the pallet racking system. All the materials stored in the VNA racking system have very high optionality, and the forklift can store any pallet of goods at any time.
1. Shelf structure
The biggest difference between the VNA racking system and the ordinary pallet racking in the racking structure is the "rail". Pallet racks are generally composed of frames, beams and other accessories; in addition to the accessories of pallet racks, VNA racking system has one more accessory than pallet racks, that is, guide rails, which are also the largest structurally. difference.
2. Shelf channel
The aisle is designed according to the size of the warehouse site and the different details of the goods. The width of the aisle of the VNA racking system is much smaller than that of the ordinary pallet rack, generally about 1600-2000mm.
Because the roadway of the VNA racking system is relatively narrow, the forklifts used are generally three-way forklifts, and the VNA racking system does not need to reserve the floor space and turning width required by traditional forklifts.
3. Storage facilities
Each type of storage rack has its own special equipment and facilities, and the same narrow aisle storage rack is also equipped with special equipment and facilities. The VNA racking system needs to be equipped with a dedicated forklift, that is, a three-way stacker forklift.
4. Warehouse utilization
Because the VNA racking system has a small channel and a high height, usually more than 10m, it is mostly used in higher warehouses, so the warehouse utilization rate of the VNA racking system can reach 50%
5. Guide rail system
After the VNA racking system is installed, a guide rail with a height of about 200MM is used as the guiding system of the forklift, which can reduce the damage to the rack caused by the forklift driver due to human factors.
6. High-density storage
When the VNA racking system stores goods, the three-way stacking forklift will slide along the prescribed guide rail route. Because the width of the stacking channel of the racking system will be larger than the width of the palletized goods, high-density storage can be easily achieved.
