A stand having a carrier (2) and a load-equalizing unit (18), in the case of which stand there is provided, between the load-equalizing unit (18) and the support arm (2), a counterbalancing transmission (106) at which, independently of the position of the load, it is possible by means of changing the position of a connecting arm (5) for a constant force (FA) output by the load-equalizing unit (18) to be changed in position for balancing purposes when there are changes in weight at the load (G).
