A handle (10) for turning a rod- or tube-formed turning corpus (54), a lift link assembly (52) and a method for producing said handle (10) is described. The handle (10) comprises deformed portions (26, 28, 30) extending parallel to an axis (12) and forming at least partially a hollow space (42, 44, 46) around the axis (12). The hollow spaces (42, 44, 46) are used for engaging with a turning corpus (54). By means of a cut-out (48) formed on the handle (10) and a protrusion (62) formed on the turning corpus (54), a torque proof connection between handle (10) and turning corpus (54) is given by engaging said cut-out (48) with said protrusion (62). It is proposed to form the deformed portions (26, 28, 30) along the axis (12) one after another, wherein at least one deformed portion (26, 28, 30) is contrarily deformed with respect to an adjacent deformed portion (26, 28, 30). Such a handle (12) can be used for adjusting a lift link assembly (52), for example on agricultural implements.
Handle with bulges (26, 28, 30), shaped parallel to an axis (12), which at least partially form a cavity (42, 44, 46) around the axis (12), characterized in that the bulges (26, 28, 30) are arranged along the axis (12) one behind the other, wherein at least one bulge (26, 28, 30) is formed in the opposite direction to an adjacent bulge (26, 28, 30), radially with respect to the axis (12).
Handle according to one or more of the preceding claims, characterized in that the bulges (26, 28, 30) are formed in at least two steps.
Handle according to one or more of the preceding claims, characterized in that it is produced from several pieces of flat steel (80, 82), which can fit into one another.
Handle according to one or more of the preceding claims, characterized in that it is made as a casting.
Handle according to one or more of the preceding claims, characterized in that it has side edge areas (18, 20) provided with a flange (50).
Handle according to one or more of the preceding claims, characterized in that the bulges (26, 28, 30) enclose a cavity (42, 44, 46) by more than 180°.
Lifting spindle arrangement with a rotating body (54), characterized in that a handle (10), according to one or more of the preceding claims, is provided on the rotating head (54), wherein the bulges (26, 28, 30) of the handle (10) are meshed with the rotating body (54) so that they can rotate and can be displaced axially.
