A crane comprises three parts articulately interconnected parts in a plane, in the form of a pillar (1), a crane arm (3) and a lifting boom (2) inserted between these. The lifting boom is provided with a main beam (6) and a parallel strut (7) pivoting parallel to the main beam, and forms, via a horizontal link (8) pivotally journaled in the main beam (6) and a knee link (9) also pivotally journaled in the main beam (6), a parallel trapezoidal geometry. A lifting yoke (24) pivotally journaled in the main beam (6) is actuated by a lifting device (20) for lifting and lowering the lifting boom (2), wherein the lifting yoke (24) forms a two-armed lever which is pivotally journaled in the main beam (6) via a pivot point (25), separate from the journaling (4) of the main beam (6) in the pillar (1).
