The article deals with the examination of the state of the ball track of the heavy mining machine ZP6600/Z79. It gives results of material exams which were taken on given samples and describes the progress and results of the numerical computation of the state of tenseness by finite element method of the bottom part of the ball track when it touches the ball.
