VNA applications are known for their narrow stacking channels (usually between 1500 mm and 1800 mm), but they have more benefits.
Some of these include:
● increase storage capacity and better space utilization
● higher lift height than wide channel solutions
● reduce the need for offsite / external storage or warehouse expansion
● faster picking rate / possibility of picking from all levels
● cost reduction per square meter
● increase productivity and throughput
However, the requirements of VNA solutions may be different from traditional wide channel solutions. Before making a choice, you should consider the following factors.
Precautions for warehouse layout in very narrow aisles
Guidance system
Since the VNA stacking channel is only slightly wider than the forklift itself, a guidance system is required to keep the forklift driving in a straight line when driving in the channel. Manual steering is disabled in the aisle, and the guidance system makes the forklift drive along the center line. The use of these systems allows the VNA forklift to travel safely at a higher speed and allows the operator to lift the "diagonal travel" while driving. The guidance system has two options: wire and railway, which can ensure safety and allow VNA forklifts to operate with the high throughput they can achieve.
Operator experience
Not all operators have experience in operating in very narrow aisles. Nevertheless, there are still a large number of training courses for new operators, conversion courses for experienced operators who may not have used VNA before, and refresher courses for operators who have used VNA in the past.
security
With the right procedures, VNA layouts are generally safer than wider aisle layouts. The mandatory use of the guidance system ensures that the forklift can travel safely along the aisle, while the end of aisle (EOA) braking system (not mandatory, but highly recommended) automatically decelerates or stops the forklift at the end of the aisle to ensure higher safety.
VNA can provide a safe and efficient storage method when there is only one forklift in each channel at any given time and pedestrians are vacant when forklifts are used. However, it is important to ensure that employees understand the correct procedures and receive comprehensive training to meet these high safety standards.
Professional handling equipment
To operate in very narrow aisles, you need to buy professional handling equipment. Special forklifts, such as single turret forklift, single turret forklift and guided advanced picker, are designed to meet the specific requirements of very narrow aisle warehouses.
Choose the right forklift
The decisive feature of VNA application is that the forklift does not turn in the stacking channel, but uses the rotating head attachment or telescopic fork on the platform to place and retrieve the pallet laterally.
Therefore, if you own or are considering using very narrow aisle shelves, you know that you need to invest in professional forklifts. But what is your choice? We offer a range of suitable models of cat forklifts, including:
