Abstract: A method for operating an industrial truck having an operating element comprising at least one operating lever and a resetting apparatus configured to interact with the at least one operating lever comprises generating resetting force that is dependent on a deflection of the least one operating lever. Determining a vehicle variable indicating a tipping moment and changing the resetting force when a critical value of the vehicle variable exists for a tipping moment of the industrial truck, wherein the resetting force increases as the tipping moment increases.

Abstract: A method for operating an industrial truck with an operating element comprising at least one operating for a vehicle function, an unlocking apparatus for the vehicle function, and a resetting apparatus configured to interact with the at least one operating lever generating a resetting force depending on a deflection of the least one operating lever. Upon an actuation of the operating lever without previously unlocking the operating lever, the resetting force acting on the at least one operating lever is changed in order to report an unsuccessful unlocking procedure.

Abstract: A control element for an industrial truck with two control levers (12, 14) and at least one switch (22, 24) arranged between the control levers, wherein the control levers (12, 14) are designed respectively for a biaxial movement (K) and are distanced from each other spatially such that the control levers, with the fingers of a hand positioned between the levers without grasping, and the at least one switch between the control levers can be operated.

Abstract: Industrial truck with an electric travel drive and controls that can switch the electric travel drive to regenerative operation to brake the industrial truck, wherein an eddy current brake is provided that can be controlled or regulated by the controls during regenerative operation to brake the industrial truck, wherein the controls control or regulate the eddy current brake depending on the rpm of the electric travel drive, and wherein the controls control or regulate the eddy current brake in a manner such that the braking torque of the travel drive is supplemented at high rpms by the braking torque generated by the eddy current brake.
