Lift trucks are classified due to the types of aisles they have been designed to work in. Wide Aisle and Narrow Aisle lift trucks are designed to turn in the aisle, whilst Very Narrow Aisle trucks actually don't turn within the aisle. There are certain aisle widths to take into account with different models.
Very Narrow Aisle trucks can work in less than 6 feet areas, whilst some would use certain guidance systems like optical, rail or wire systems in order to travel in the aisles. Several different models of VNA trucks consist of Order Selectors, Turret Trucks and Swing Masts. These are popular models in compact retail areas and in some storage and warehouse situations.
Narrow Aisle or NA trucks can work in aisles which are 8 feet to 10 feet. Usually these are stand-up units such as Reach Trucks. They are usually used within storage facilities and warehouses.
Wide Aisle Standard forklifts fall into this truck category and are designed to work in aisles that are more than 11 feet wide.
The "Ergomat" padding on stand-up models provide padding on a sloped floorboard. These features are made to reduce operator fatigue by absorbing vibration. The compartment for the driver is really big and has an 8" low step height which helps reduce overall body exhaustion by easing frequent entry and exit. The model includes 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 together with a backrest designed to help keep drivers comfortable and thus more productive while limiting exhaustion.
