Abstract: One of the highly loaded units of the machine, in particular, and the quarry dump truck are the wheel fastening elements. The fastening elements include threaded parts (nuts, studs or bolts), which are used to fix the wheels on the hub. The fastening elements perceive all vertical loads acting on the car, horizontal forces and moments that occur during turning, braking and movement, so they must ensure the safety of the machine. It is noted that the ability to determine the loads on the fastening elements allows you to select the optimal number of studs (bolts), thereby ensuring the safety of the machine. In this article, the APM Joint module of the WinMachine system is used to determine the loads on the fastening elements of the front axle wheels. A general characteristic of the forces that act on the wheel during movement is given. A calculation case for rectilinear movement with a lateral angle of inclination is adopted, the forces acting on the front wheel of a quarry dump truck with a lifting capacity of 220 tons are determined and calculated. In the APM Joint module, the geometry and parameters of stud connections are specified, the acting loads are placed, and additional information with the necessary coefficients for meeting the conditions for non-opening and shear of the connection is indicated. The calculation results are reports and maps with the obtained pressures and loads. The report indicates the maximum load on the stud and the pressure on the contact surface, as well as the required tightening torque. The map can be used to determine the distribution of loads and pressures on the studs and contact surface
