The main driving force will be oil. Therefore, a low-power motor capable of driving the oil pump is necessary. At first, I chose a single-circuit oil pump with a volume of 10 cm³. However, this will greatly limit the potential of the loader. Practice has shown that when all consumers - motors, hydraulic cylinders, and the swing pump - are connected in series, it is impossible to achieve simultaneous operation. Only one at a time. Therefore, I used a dual-circuit pump. The movement is one circuit, the lifting of the boom and rotation is the second circuit. Of course, three circuits would be even better, but the cost of such a pump is significantly inflated, and as I mentioned earlier, I am looking for a cost-effective yet functional machine option.
