The publication deals with the problem of assessing the mining excavator stability with a variable cab position. It is determined that the efficiency of the excavator cycle operations largely depends on the position of the operator with respect to the boom and body, the glazing area of the cabin, the dimensions of the windows, the width and the number of jumpers. A technical solution is proposed to increase the visibility of mining excavators’ cabs. The design of the mechanism makes it possible to advance the efficiency of using quarry excavators by changing the position of the cabin both in the vertical plane and in the horizontal one. Counterweight mass, an assessment of the turntable equilibrium and the stability of a mining excavator with a variable cab position are performed using standard «MS Excel» tools.
