VNA pallet racking, high level of inventory. Fast rotation. High in & out throughput requirement. Nanjing Huayide high density and flexible storage system supplier.
VNA Racking
Verry Narrow Aisle (VNA) Racking is available in many designs. The assembly is adapted to the respective application and is derived from various design criteria. The most important design criteria for racking are the unit load types, load weights and dimensions and the trucks being used. Selective pallet tacking is used as the primary storage in narrow aisle systems. The racking can be constructed as single or multi-position systems dependent on the load weight. Static tests are based on EN 15512, Steel static storage systems- Adjustable pallet racking systems-Principles for structural design. In addition, HUAYIDE pallet racking systems conform to the following European standards: EN 15620 -EN 15629- EN 15635.
The assembly of free-standing pallet racking is flexible as it is not connected to the building. Our customers have the option of later changes if the application conditions change.

What do you need to do for preparing a VNA warehouse?
It is critical to correctly plan the interfaces between rack and trucks including all relevant safety distances and racking clearances. The project management of these interfaces are vital for the success of a project.

Guidance System
To minimize the aisle width, fork trucks in narrow aisle systems operate with minimum safety distance to the racking. Hence guidance system is a must for fork trucks operate in a VNA warehouse. Guidance systems ensure safe operation and are the basis for high throughput.
Dependent on the type of truck, there are three options for guidance:
A.Rail Guide. The truck is mechanically guided between two steel profiles bolted to the floor. Rollers fitted on the side of the chassis, 2-3 on each side, keep the truck between the rails in the centre of the aisle.
B.Wire Guide. Installed by the fork truck supplier. The inductively guided truck follows a guide wire laid in the floor. A frequency generator feeds the guide wire with high frequency alternating current (low voltage). The current produces a concentric electromagnetic field. Antennae fitted to the truck recognize this field. Thus every deviation of the truck to the guide wire is registered. A compensation steering process is automatically initiated so the truck is safely controlled in the aisle.
C.Rail Guide with second cement pouring, implemented by civil engineering supplier.
Wire guide is more popular used in current stage.
Floor
The function and productivity of a narrow aisle warehouse is decisively influenced by the floor, and in particular by its flatness. The Sub-base and floor plate must be dimensioned in such a way that permitted tolerances are not exceeded under load conditions. Bellowing floor flatness standards shall be followed when implementing a VNA pallet racking warehouse:
TR34 AND TR34 Appendix C
CEN15620
DIN 15185
ACI Fmin100
