PROBLEM TO BE SOLVED: To provide a lift control device capable of reconfiguring an upper limit according to an intention of an operator as much as possible while avoiding unintentional lowering of a ground working device.SOLUTION: The lift control device includes a height sensor 901 for detecting the height of a ground working device 22 attached to a traveling work device via a lift mechanism 23 and outputting a height detection signal; an upper limit control unit 71 for setting the upper limit position of the ground working device on the basis of an operation input signal from an input operation device USD for setting the upper limit; and a setting prohibition unit 72 for prohibiting setting of the upper limit position based on the operation input signal and setting the upper limit position to the height of the ground working device according to the height detection signal when the upper limit position set by the operation input signal is lower than the height of the ground working device according to the height detection signal.SELECTED DRAWING: Figure 1 |
