The invention relates to a simulator for a crane, a construction machine or an industrial truck, provided with a control station including at least one input means for inputting control commands, a graphical simulation module for calculating a virtual representation of the machine surroundings and/or machine components visible from the control station, such as a boom or a load hook, and a display device for displaying the calculated virtual representation, a movement simulation module being provided for determining movements and/or deformations of the machine components according to the inputted control commands, according to which the graphical simulation module calculates the virtual representation. According to the invention, the control station is movably mounted and can be moved by a drive device according to the movements and/or deformation of the machine components determined by the movement simulation module.
