プリング４７を介挿した作業機の水平制御装置。 A telescoping mechanism 19 consisting of a double-acting cylinder is interposed between the lift arm 5 provided on the traveling vehicle body side and the lower link 13, and the horizontal movement of the working machine attached to the lower link 13 is achieved by the expansion and contraction of the telescoping mechanism 19. In the control mechanism, a horizontal control device for the work machine includes a spring 47 inserted between the slide rod 25 side and the cylinder 27 side of the telescopic mechanism 19 to bias the double-acting cylinder in the contraction direction when the work machine is in a horizontal state. .
