A crane lifting device, and method for raising and/or lowering a load-handling element of a crane lifting device, allows for operating the lifting device with a first velocity or with a second velocity greater than the first velocity, by means of a control unit. To achieve a reduction in impulses while raising the load-handling element, and to achieve an extended service life of the supporting means, an inclination sensor is used to determine an inclination angle of the load-handling element and/or a state sensor is used to determine a free or occupied state of the load-handling element. An evaluating unit interacts with the control unit in such a way that, depending on the determined inclination angle and/or the determined free or occupied state, the evaluation unit prevents or permits operation of the lifting device with the second velocity by means of the control unit.
