AUTO-DESEL APPARATUS USING GRIP SENSORS

摘要

PURPOSE:To permit the function of an auto-desel apparatus to be developed more by installing a control means for outputting the desel signal for instructing the low-speed operation of an engine on the basis of the output signals of grip sensors. CONSTITUTION:Grip sensors 41 and 51 equipped with a detection part which senses the approach or contact of hand or finger are installed at the holding parts of the operating levers 40 and 50 of a construction machine. A control lever 20 outputs a desel signal for instructing the low-speed revolution of the engine 15 of the construction machine on the basis of the output signals of the grip sensors 41 and 51. The desel signal turns-ON a solenoid valve 9 to supply the pressurized-oil discharged from a hydraulic pump 32 into a desel cylinder 18, and the number of engine revolution is reduced. Thus, the function of the auto- desel apparatus can be effectively developed.
