Support joint for a carrier arm of a medical stand device

A carrier arm joint device for a carrier arm of a stand device for arranging in the operating room and for displacing a medical device held on the carrier arm is configured for setting a payload corresponding to a weight of the medical device to be taken up by the carrier arm. The device includes at least one pivot axis for mounting at least one strut of the carrier arm, respectively; and a support axis for supporting a lever configured to transmit forces holding the carrier arm between the strut and the carrier arm joint device A distance between the axes is adjustable within an adjustment range in order to set the payload; the size and/or the extent of the adjustment range is independent of the position of the pivot axis. It is possible to maximize the adjustment range and therefore the payload spectrum in a comparatively compact and structurally rigid joint. A carrier system and a stand device can include at least one such carrier arm joint device.
