Lift trucks are classified due to the kinds of aisles they have been designed to operate in. Narrow Aisle and Wide Aisle lift trucks are designed to turn in the aisle, whereas Very Narrow Aisle trucks really don't turn in the aisle. There are certain aisle widths to consider with various models.
Very Narrow Aisle or VNA trucks work in less than 6 feet areas and normally utilize certain guidance systems such as wire, optical or rail systems in order to travel in the aisles. Several various models of VNA trucks include Turret Trucks, Swing Masts and Order Selectors. These are popular models in tight retail areas and in some warehouse and storage situations.
Narrow Aisle or NA trucks can operate in aisles that are 8 feet to 10 feet. Normally these are stand-up models such as Reach Trucks. They are usually utilized in warehouses and storage facilities.
The wide aisle forklift is designed to work within aisles more than 8 feet to 10 feet.
The stand-up ergonomics include "Ergomat" padding with a sloped floorboard that is designed to lessen operator fatigue by absorbing vibration. The operator compartment is very large and has an 8" low step height that helps reduce overall body fatigue by easing frequent exit and entry. The model consists of polyurethane steer tires to absorb vibration and shocks caused by uneven floor in order to allow smooth traveling. For added comfort, there is a cushioned armrest and floor mat as well as a backrest designed to help keep operators comfortable and therefore more effective while limiting exhaustion.
