In many industrial applications is taken to consider change of payload potential energy while lifting it. It allows obtained directly benefits. For example, the cost of material loaded on a dump truck in a composition of coal is generally priced by its weight. In this case, the truck has to pass a stationary scale twice to identify its payload, before and after loading. Measuring weight of the material instantly while loading the truck, increases the efficiency of the process and makes a stationary scale unnecessary. In addition, it is possible to prevent overloading of means of transport, which use public roads, and can be weighed by the road service. The typical solutions of the static and dynamic weighing system from market were compared. The theoretical model is presented basing on geometrical and mass parameters of excavator CAT 301.5. The weighing system used in off-road machines is usually based on the measurement of the working fluid pressure in the piston chambers of the hydraulic cylinders, which lift the machine work equipment together with a payload. In this article is shown a solution with load pin, which allows the determination of the load mass independently of the several factors affecting the classic weighing system. The possibility of payload mass measuring on the excavator was estimated during tests on prepared research stand. There were obtained a good agreement of experimental research results with the mathematical model.
