Very Narrow Aisle System (VNA)

A VNA system permits the narrowest working aisles for high density storage, dictated by the load size and not by the operation of the truck. It also achieves the maximum stack heights on racking, whilst maintaining 100 % load access, high work throughput rates and the flexibility associated with free ranging truck systems in general.

However, the VNA truck cannot be treated in isolation. To be successful, all elements of the system must be agreed and achieved:

• (i) The customer specified load size and pallet must be maintained.
• (ii) The floor levels have to be to defined standards and high strength is essential.
• (iii) The racking must be correctly erected and maintained to defined tolerances.
• (iv) A guidance system is necessary within the working aisles.
• (v) Pick and deposit stations are required.
• (vi) Stock control disciplines have to match the VNA trucks capability.
• (vii) Efficient communication to and from the truck operator is also important.
