Abstract: A method automatically adjusts a variable boom position of an adjustable distributor boom of a building material pump apparatus and/or thick matter pump apparatus. At least one same tip position of a boom tip of the distributor boom can be achieved by way of different boom positions. The method determines and adjusts a boom position depending on a predefined quantity in a manner which determines a tip position and on the basis of an optimization criterion, the optimization criterion being a minimized tilting moment of the distributor boom in relation to a support system of the building material pump apparatus and/or thick matter pump apparatus. The tilting moment depends on the boom position.
