Kinds 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, whereas Very Narrow Aisle trucks actually don't turn within the aisle. There are some aisle widths to take into account with different models.
VNA or Very Narrow Aisle trucks work in less than 6 feet places and normally use specific guidance systems such as rail, wire or optical 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 kinds in tight retail spaces and in several warehouse and storage situations.
Narrow Aisle or NA trucks are able to work within aisles which are 8 feet to 10 feet. Usually these are stand-up models like for example Reach Trucks. They are often used in warehouses and storage facilities.
Wide Aisle Standard forklifts fall into this truck category and are designed to work in 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 designed to lessen operator fatigue by absorbing vibration. The compartment for the driver is big and has an 8" low step height which helps lessen overall body exhaustion 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 operators comfortable and therefore more productive while limiting exhaustion.
