Beschreibung
Zusammenfassung:	The utility model provides a hydraulic shovel power protection controlling means, the action bars is received driver's instruction and is fed back the signal of telecommunication to hydraulic pump flow instruction generater, flow instruction by each hydraulic pump on the hydraulic pump flow instruction generater formation excavator, pressure sensor measures the outlet pressure of each hydraulic pump, send the power demand that obtains each hydraulic pump to hydraulic pump load limiter, speed sensor detects the real -time rotational speed of engine, send the calculator to engine power, calculation obtains engine power and exports hydraulic pump load limiter, hydraulic pump load limiter is with the power demand of each hydraulic pump of the biggest available power of hydraulic pump restriction, hydraulic pump flow restrictor is according to each hydraulic pump of power demand drive after restricting. The utility model provides the power of high hydraulic pump - engine matches degree, equipment's operating efficiency and hydraulic shovel's energy -conservation nature, makes the equipment motion of excavator more smooth -going.
