Description

The present invention relates to the technical field of weight measurement, and specifically to a weight measuring device having a mucking function.

Currently, when inspecting cargo in and out of many factories, the cargo is generally inspected by the weight measurement method, the weight is measured on the truck scale in the case of large cargo, and the small cargo is generally convenient to carry. However, there is no weight measuring device with a macking function for delicate cargo that cannot be divided into several parts even if it is not large, so the cargo is manually loaded. Or, there is no choice but to unload, wasting time and effort, and after the weight measurement is completed, the data cannot correspond to the cargo, and it becomes a phenomenon of repeatedly measuring the weight, and the cargo is automatically loaded or unloaded to reduce the amount of labor.
