業部の上昇速度制御装置。 In a ground work vehicle comprising a traveling body and a work part for performing ground work connected to the ground work so as to be operable to raise and lower, the ground work vehicle has a rising speed control section of the work part that detects whether or not the work part is in a ground work state. In addition to connecting the detection means, the climbing speed control section includes a climbing speed switching means capable of switching and outputting a climbing speed command, and a rising speed switching means that outputs a low speed climbing command when the detection signal from the ground work detection means is a ground work signal. 1. A rising speed control device for a working part in a ground work vehicle, characterized in that a speed switching judgment means is provided.
