摘要

Self-propelling uniaxial machine comprises a switching device having a first mechanical control unit for an oil stream arranged between tension drives and an adjustable valve of a hydraulic pump and a second mechanical control unit arranged between further tension drives for steering movement and a steering valve of the pump. A control part of the first control unit pivots with guiding capping pieces (8, 9) about their pivoting axle. Preferred Features: One tension drive (18) is guided on the connecting point of a control rod via a deviating roller.
