The present invention installs load cells inside each corner of the load plate of the weighing scale to ensure the stability of the weighing scale and at the same time tightly fixes the load pin connection to prevent detachment and breakage, and the weight of the truck is measured more accurately. The present invention relates to a weighing scale for trucks.;The present invention provides a load cell device and a flow prevention device located inside each corner of the lower side of the weighing scale load plate to achieve a stable balance of the weighing scale and minimizes the flow of the load plate due to the rise and fall of the truck. In order to obtain accurate measurement at the position, and to connect the load plates to form a weighing scale, the load plate and another load plate are connected in intimate contact with each other so that the load of the loaded truck is evenly transmitted. And it is characterized in that it is possible to prevent the bending or breakage of the connection portion that was a weak part.
