Narrow Aisle and Wide Aisle lift trucks are classed due to the kinds of aisles they have been designed to operate in. These machines could turn in an aisle, whilst Very Narrow Aisle trucks really don't turn within the aisle. There are several aisle widths to take into account with various models.
VNA or Very Narrow Aisle trucks work in less than 6 feet areas and usually use particular guidance systems such as rail, wire or optical systems in order to travel in the aisles. Some different models of VNA trucks consist of Turret Trucks, Swing Masts and Order Selectors. These are common kinds in compact retail areas and in some warehouse and storage situations.
NA or Narrow Aisle trucks could operate in aisles that are 8 feet to 10 feet. Normally these are stand-up units like Reach Trucks. They are usually used in storage facilities and warehouses.
The wide aisle forklift is designed to work in aisles more than 8 feet to 10 feet.
The stand-up ergonomics include "Ergomat" padding with a sloped floorboard which is designed to reduce operator exhaustion by absorbing vibration. The operator compartment is large and has an 8" low step height which helps lessen overall body exhaustion by easing frequent entry and exit. The model consists of polyurethane steer tires to absorb shocks and vibration caused by uneven floor in order to allow smooth traveling. For additional comfort, there is a floor mat and a cushioned armrest together with a backrest designed to help keep drivers comfortable and thus more productive while limiting fatigue.
