ABSTRACT:
A livestock scale has a weighing platform supported by a support apparatus and is vertically movable relative thereto. A weighing mechanism is provided and indicates the weight of a load received on the platform. Primary and secondary scale arms are pivotally connected to the support apparatus and the weighing platform by hanging links. A connecting link connects the primary scale arm to the secondary scale arm along a medial segment of the secondary scale arm. A weight indicator is held by the support apparatus and is connected to the primary scale arm for indicating a weight in predetermined proportion to the weight of the load on the platform. Horizontal movement of the weighing platform is restrained by a pair of lateral sway bars and a longitudinal sway link, while vertical deflection of the weighing platform during weighing is not inhibited thereby. The sway link forms a parallelogram configuration with the primary scale arm and the primary hanging link and associated support apparatus. Alternatively, flexible restraints are connected to the structure and the weighing platform for restraining horizontal movement of the platform.
