Kinds of Aisles
Lift trucks are classified due to the types of aisles they have been designed to operate in. Wide Aisle and Narrow Aisle lift trucks are designed to turn in the aisle, whilst Very Narrow Aisle trucks really don't turn in the aisle. There are several aisle widths to consider with various units.
VNA or Very Narrow Aisle trucks work in less than 6 feet places and usually use specific guidance systems such as wire, optical or rail systems in order to travel in the aisles. Several different models of VNA trucks comprise Swing Masts, Order Selectors and Turret Trucks. These are popular models in tight retail spaces and in some storage and warehouse situations.
NA or Narrow Aisle trucks could work within aisles that are 8 feet to 10 feet. Usually these are stand-up units such as Reach Trucks. They are usually utilized in warehouses and storage facilities.
The wide aisle forklift is designed to work in aisles more than 8 feet to 10 feet.
Stand-Up Ergonomics
The "Ergomat" padding on stand-up units provide padding on a sloped floorboard. These features are made to lessen operator fatigue by absorbing vibration. The operator compartment is spacious and has an 8" low step height that helps lessen overall body fatigue by easing frequent entry and exit. The unit consists of polyurethane steer tires to absorb vibration and shocks 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 operators comfortable and therefore more effective while limiting exhaustion.
