Abstract: The relevance of the work is due to the need of design departments engaged in the design of hydraulic ex-cavators in methods that allow to reduce the mass of excavators while ensuring at the same time reliability and the required technological capabilities.
Purpose of the work: development of a mathematical description for calculating the efforts in the elements of the working equipment when digging with one side of the bucket.
Results. For a hydraulic excavator with "front shovel" working equipment, a mathematical model has been developed for calculating the forces when digging with one side of the bucket (all the effort is on the extreme tooth), an algorithm and a program in algorithmic language that allow you to determine possible forces in the elements of the working equipment. The values of the efforts can be used to calculate the stress state of the working equipment and the selection of rational sections of the working equipment elements.
Conclusions. The compiled mathematical description allows you to take into account the change in the ef-forts when digging with one side of the bucket compared to the efforts when digging with all teeth.
