An industrial truck has a tiller that can pivot around a horizontal axis and a traction drive motor that can be controlled by an operator by a traction drive switch. The maximum speed of travel of the industrial truck can be set by an electrical control unit as a function of the pivot angle of the tiller. The maximum speed of the industrial truck is a function of the pivot angle of the tiller. At least one segment of the pivoting range of the tiller is provided with variable maximum speed, in which the maximum speed of travel varies continuously with the pivoting angle. The division of the pivoting range of the tiller into the segment with variable maximum speed and at least one additional segment is made by the control unit as a function of the signal of a continuous or incremental sensor.
