TRENCHER WITH AUTOMATIC PENETRATION AND BOOM DEPTH ADJUSTMENT

摘要

FIELD: transport.;SUBSTANCE: invention relates to earth mover control systems. Shovel penetration drive control device incorporates the drive and the controller to generate output signal to vary shovel penetration rate. Note here that said controller can detect drive rpm range wherein actuator output signal increase at increase in drive rpm and, on the contrary, decrease at its decrease. Besides, proposed system comprises user's interface for manual control over drive rpm.;EFFECT: higher efficiency owing to better adaptability to varying conditions.;11 cl, 28 dwg
