Method for actuating a hydraulically movable boom of a working equipment, and a working equipment. The invention relates to a method and to a working equipment for actuating a hydraulically movable working element (24), which is provided on a main body (14) of a working equipment (11), comprising at least one main cylinder (19) and at least one additional cylinder (28), which are supplied with pressure medium to generate a pivoting movement, wherein the pivoting movement in the rapid motion mode is actuated in a first working pressure range of the hydraulic control device (32), the pivoting movement in a working motion mode is actuated in a second working pressure range, which is higher than the first working pressure range, the pivoting movement in the heavy load motion mode is actuated in a third working pressure range, which is higher than the first and second working pressure ranges, and the pivoting movement of the working element (24) in the operating modes of rapid motion, working motion or heavy load motion is actuated in accordance with the prevailing working pressure.
