(57) Abstract Objective The regulation by the moment regulation valve really necessaryOnly when it becomes main point, power supply from the batteryElectricity retrenchment is assured. Constitution In operation of the job device with manipulation unit 26 application/responseAs the moment operation to the ji te hull is calculated thisWay moment is held down inside the specified range, moment regulationThe moment regulation short story low/row which controls the operation of valve 40ra the manipulation detection which detects 27 and battery b and manipulation stateSensor ri where does the stopping/deciding connection control of 31 and electricity supply line 33Possessing with race/lace itch 35, the electricity economy system is formed,ru. As for this relay switch 35, manipulation unit 26 virtueWhen to work state being is detected, becoming onThrough electricity supply line 33, to make power supply possible, virtueThat to non manipulation state being work unit 26 was detectedIn coming, becoming off, through electricity supply line 33, electricityPower supply is obstructed.
