Types of Aisles
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, whilst Very Narrow Aisle trucks really don't turn in the aisle. There are certain aisle widths to take into consideration with different models.
VNA or Very Narrow Aisle trucks operate in less than 6 feet places and usually use particular guidance systems such as rail, wire or optical systems in order to travel within the aisles. Several different models of VNA trucks include Order Selectors, Turret Trucks and Swing Masts. These are common models in compact retail areas and in some warehouse and storage situations.
Narrow Aisle or NA trucks can operate within aisles which are 8 feet to 10 feet. Usually these are stand-up models such as Reach Trucks. They are commonly used within storage facilities and warehouses.
Wide Aisle Standard forklifts fall into this truck category and are designed to work within aisles which are more than 11 feet wide.
Stand-Up Ergonomics
The "Ergomat" padding on stand-up units offer padding on a sloped floorboard. These features are made to reduce operator exhaustion by absorbing vibration. The operator compartment is really spacious and has an 8" low step height that helps lessen overall body fatigue by easing frequent exit and entry. The unit consists of polyurethane steer tires to absorb vibration and shocks caused by uneven floor in order to enable smooth traveling. For added comfort, there is a cushioned armrest and floor mat as well as a backrest designed to help keep drivers comfortable and hence more productive while limiting fatigue.
