Link member for connection of a gripping assembly to a hydraulic crane arm with integrated dynamic weighing assembly, wherein such link member is furnished with two pivot joints (1, 2), which are in direction of vertical axis spaced apart from each other, namely a top pivot joint, which is arranged on the side of a crane arm, and a bottom pivot joint, which is arranged on the side of a rotator or a gripping assembly for handling each load, wherein said pivot joints (1, 2) are conceived substantially as a Cardan joint, and rotational axis (X, Y) thereof, around which said link member can be pivoted relatively to the crane arm and/or relatively to said rotator, extend parallel to each other, and wherein said bottom pivot joint of the link member is adjusted for pivotally connecting said link member with said rotator and is conceived as an eye and furnished with a throughout passage, which extends along said rotational axis of the bottom pivot joint and is adjusted to receive a bolt for establishing a pivotal connection with said rotator, which then allows pivoting around said axis, and wherein said top pivot joint of the link member is adjusted for pivotally connecting said link member with said crane arm and is conceived as an eye and furnished with a throughout passage, which extends along said rotational axis of the top pivot joint and is adjusted to receive a bolt for establishing a pivotal connection with said crane arm, which then allows pivoting around said axis, characterized in that the bottom link member is furnished with a prismatic piece of a square cross-section, which extends coaxially with said central axis towards the top pivot joint and is on its terminal end portion furnished with a threaded bolt, which is furnished with a centrally arranged blind bore, into which a screw is screwed, which is on its first end portion furnished with a left oriented thread and on its opposite end portion with a right oriented thread, wherein a compensating assembly is inserted between said top pivot joint and said bottom pivot joint of the link member, and is formed by two groups of plates, which are separated from each other by means of spacers, wherein each group consists of several plates, which are arranged in a sequence each above another and each of them is furnished with a centrally arranged substantially square-shaped passage, which is adjusted to the shape and dimensions of said prismatic piece on the bottom pivot joint of the link member, and wherein each of said plates is furnished with a sequence of throughout bores, which are arranged along its circumference and are spaced from the external edge and equidistantly spaced apart from each other, as well as with two longitudinal recesses (43', 43"), which are spaced apart from each other, and wherein said plates in each group are alternatively arranged, so that said recesses (43', 43") of each particular plate are arranged perpendicularly with respect to recesses (43', 43") of each plate located below or above it, or vice versa, while said plates and said spacers are connected with each other by means of screws, which extend through said bores within the plates, and wherein a cover plate is foreseen above said compensating assembly, and is by means of a nut and a washer, which are arranged on said threaded bolt on the prismatic piece on the bottom pivot joint, attached to said bottom pivot joint, wherein said screw protrudes through said cover plate towards the top pivot joint, and wherein a supporting plate is arranged above said cover plate and is firmly connected to said top pivot joint and furnished with two supporting members (60', 60"), which are spaced apart from each other and are arranged on the side of said top pivot joint symmetrically with respect to said central axis of the link member, and a bending beam is rest on said support members (60', 60") and is screwed to said supporting plate in two locations symmetrically with respect to said central axis, wherein said bending beam is uniformly conceived and comprises two supporting areas (70', 70"), which are arranged correspondingly to said supporting members (60', 60") on said supporting plate and between which two one above the other arranged bridges (71, 72) are available, namely a thicker bottom bridge, which is furnished with a central throughout bore, through which said screw extends, to which said bridge is attached by means of a nut, as well as a thinner and bending deformable top bridge, on the external surface of which, namely on its surface faced towards the top pivot joint, two sensors (91, 92) are attached, which are suitable for detecting each extensions and are arranged symmetrically with respect to the central axis, while at the same time also two sensors (93, 94) for detecting any movements are foreseen, each of them includes both a sensor for detection of accelerations and a gyroscope, wherein the first sensor is located in the area of said link member, namely in the area between the first point on said axis extending through the top pivot joint and the second point, which is located on said axis extending through the bottom pivot joint and below said first point, while the second sensor is located in the area of said rotator at a sufficient distance apart from said second point on the axis extending through the bottom pivot joint of the link member.
