PROBLEM TO BE SOLVED: To provide an inexpensive and highly reliable boom interlock mechanism by detecting the operation of an outrigger jack to a contraction side.SOLUTION: A boom interlock device for a work vehicle includes a pair of left and right outriggers 3, a work machine having a boom, two sets of jack operation levers 5 for individually extending/contracting the jacks of the left and right outriggers, and detection means 6 for detecting the operation of each jack operation lever to a jack contraction side. The detection means 6 is configured by including a single operation body 61 directly pressed by each jack operation lever when any one of the two sets of jack operation levers is operated to the jack contraction side to operate at a jack contraction operation detection position, and a single detector 68 for detecting the operation of the operation body 61 at the position. Thus, the inexpensive boom interlock mechanism can be provided.SELECTED DRAWING: Figure 3 |
