Abstract

PURPOSE:To perform a self-stop to a horizontal condition from a rising and an earth-moving state, by a method wherein solenoids are mounted to a spool operating in synchronism with a control lever, and normally-opening of a switch is changed over to and from a normally-closing by means of a guide rod moving in synchronism with a bucket cylinder. CONSTITUTION:Solenoids 21 and 21' are mounted to both sides of a spool operating in synchronism with a bucket control lever 18, and a guide rod 12 with 1 step changing point, moving in synchronism with a bucket cylinder 5, is installed. If the lever 18 is brought down in an A-direction, in order to bring a bucket bottom plate to a horizontal grounding state from a rising state, the spool 20 is excited by the solenoid 21' to hold a hydraulic switch valve 17 in a switching state, and if a detecting roller 16 contacts a changing point 23, a switching contact type switch 29 is changed over, and the lever 18 returns back to a neutral position. On the contrary, if the lever is brought down in 3 directions in order to bring the bucket bottom plate to a horizontal position from an earth-moving position, a hydraulic circuit is released from holding.
