The article describes the main principles of the movement around the circumference of the cranes circular steps. It is proved that the defining characteristics of the organization of the movement of the crane on the circle are the geometric parameters of the mutual reversal of the running wheels of the crane, not the observance of the reversal determines the transverse slippage of wheels of the crane, and the shape of the wheels depends only on the elastic longitudinal slide. The result of slides and slippage is firing the head of the rail with one hand and the loss of stability when moving the crane. Stability stability ensures the achievement of the precision targeting of the gripping device. These parameters are the main performance characteristics that should be valued in absolute terms should be minimal.
