When the loader loads the bulk cargo, the weight of the loaded cargo is calculated by measuring the specific gravity and drawing the line at the initial stage. This method has the characteristics of large error, randomness and inconvenient management. More loading, will cause direct economic losses and overload transportation; Less load, it will reduce the efficiency of transportation, damage to the interests of customers. At the same time, because the loader has no weighing device, the loading and unloading of materials must also rely on the automobile transfer weighing or the use of loadometer, and the loading and unloading efficiency is low and the cost is high. Generally speaking, the higher the accuracy of the measurement of goods, the better. The weighing error is generally required to be about 0.1% ~ 0.5%.
The loader/forklift is self-heavy, the wheelbase is short, and it is always in the state of flowing operation. It is difficult to weigh the goods carried by it with a fixed position weighing device, otherwise it will affect the work efficiency. With the development of railway, automobile, port, dock and other logistics loading and unloading industry, the requirements of loading and loading efficiency, safety and accuracy are more and more high, urgent need of a convenient, effective, intuitive measuring means to realize loading and weighing management.
As a result, loader scales and other electronic weighing devices emerged. After installing the corresponding loader/forklift scale on the loader/forklift, automatic weighing and measurement can be carried out at the same time of loading and unloading operation, which has significant practical effect on strengthening the management of loading operation, preventing overload and underload, improving the efficiency and benefit of loading and unloading operation, and ensuring the safety of vehicle transportation.
