Abstract: The main mechanisms of single-bucket excavators include lifting,
pressure (traction), rotary and running mechanisms, which have different types of loads
during excavator operation. The operation of the lifting, pressure and rotary
mechanisms is cyclical. The operation of the rotary mechanisms is associated with
overcoming large moments of inertia of the rotating parts of excavators. If we exclude
short-term maneuvering operations with a bucket over the unloading site from the
excavator operation cycle, then in calculations to determine the power of the drive
motors of the lifting, pressure and rotary mechanisms, the cycle time can be divided
into three periods: digging, turning the platform with a loaded bucket to the unloading
site and turning the platform with an empty bucket into the face.
