Abstract (en)
The invention relates to a forklift (1) comprising a load carrier (9), coupled to a mast, a control unit, at least one drive wheel (17), at least one support wheel (13), and at least one sensor device (21) for detection of a guiding device (23), wherein the forklift (1) may be operated in a free-range mode and at least a semi-automatic mode. The forklift further comprises at least one auxiliary wheel (25), selectively movable between a lower position (37) in which a resilient contact between an underlying floor surface (27) and said at least one auxiliary wheel (25) is established, and an elevated position (47) in which said at least one auxiliary wheel (25) is elevated from said floor surface (27). The control unit is arranged to receive an indication that a transversal operation of the load carrier (9) is initiated, and to detect that the at least one auxiliary wheel (25) is in resilient contact with the underlying floor surface (27), wherein the control unit controls the at least one auxiliary wheel (25) to shift from a resilient contact to a rigid contact with the underlying floor surface (27). The invention also relates to a method for performing a material handling operation with a forklift (1), wherein the method provides an improved stability to said forklift (1), and software for using the method.
