    Tips: Why can't the crane scale overload?
    The crane scale is an electronic weighing scale that weighs goods during space lifting. So it is not a static weighing method. However, in order to improve the weighing accuracy, it is not allowed to weigh under dynamic conditions. Therefore, the crane scale is mostly in the quasi-dynamic weighing mode when weighing. That is to say the goods is weighing in the state of uniform motion or near static. Therefore, the load cell is not only subject to the weight of the lifting object during the weighing process. It is also affected several kinds of forces as follows:

    1. The crane, wire rope and load cell form a synthetic elastic vibration system. After the wire rope lifts the heavy object, a synthetic low-frequency vibration will be generated. For a high capacity crane, it equivalent to a constant frequency vibration of about 15hz, the load cell is subjected to the effect of alternating vibrations.
    2. After lifting the object, since the center of gravity of the object is not perpendicular to the fulcrum, it will inevitably cause the object to oscillate, which is affected by factors such as mechanical friction and air resistance during the movement, resulting in the attenuation of the gravity of the load cell. On the other hand, the load cell will receive a centrifugal force due to the swing of the heavy object. Generally, the weighing error caused by the swing angle of 70 degrees is 0.2-0.3%.
    3. The force value caused by the change of positive and negative acceleration of the heavy object when the crane is moving up and down.
    4. The impact force generated by the inertial motion of the heavy object during braking.
    5. Gravity tilt caused by the change of the acceleration of the horizontal direction of the object when the crane do translational motion.
    6. The center of gravity of the heavy object is not perpendicular to the hanging point when lifting. It also causes rotation, which causes the load cell to introduce a torsional moment.

    It can be seen that the crane scale is a complicated process after the cargo is lifted. It is not only affected by the gravity of the cargo, but also by many other forces. Therefore, we must pay attention to the weighing of the load cell when weighing, otherwise it will easily cause damage to the crane scale.
