ABSTRACT:
In a winding drum for a chain strand, which is mounted in a support frame by means of a mounting support device so as to be rotatable relative to the latter and which has a central winding shaft, lateral butting rings and on either side a central receptacle for the support device, the latter comprises a shaped plug, which can be non-positively brought into plug connection with the receptacle and with which, in its plugged-in position on rotating the winding drum, with respect thereto, in frictionally resistant manner, a brake torque can be applied to the drum. The plug has a shaped portion projecting axially over the butting ring towards the support frame and also has a non-rotationally symmetrical outer profile for the non-rotary mounting in the support frame.
