The structural design of the mechanism of stabilization of horizontal position of the shelf of elevator shelving with a chain drive is proposed. The analytical dependencies for determination of the motion trajectory of supporting and guiding rollers of the shelf supporting mechanism are derived. The formulas for defining the horizontal and vertical displacement of the center of the arc of the trajectory of the guiding roller relative to the center of the driving star of the chain transmission during the shelf passing through the "characteristic" regions are presented. The adequacy of the obtained analytical dependences has been substantiated by analyzing the hinges coordinates in the boundary points of each of the sections of the shelf motion trajectory.
