The present invention relates to a lifting gear such as a crane, in particular a tower crane, having a lifting mechanism for lifting a load, a lifting mechanism drive for driving the lifting gear and a control device for controlling the lifting mechanism drive, as well as a method for starting up the lifting mechanism of such a lifting gear for gentle lifting of the load. In this case, in a phase for initial tensioning of the lifting means, the tightening torque of the lifting mechanism drive is automatically limited by the control device to an initial maximum torque that is only slightly greater than a load-free lifting resistance torque of the lifting mechanism, and then in a further phase, when the load on the lifting mechanism due to the tensioning lifting means increases from the load to be picked up and/or a drive speed of the lifting mechanism drive decreases, for further tightening the maximum torque increases in a load-induced manner and/or a rate of change of the drive speed of the lifting mechanism drive is limited to a maximum tightening acceleration.
