<p><P>PROBLEM TO BE SOLVED: To solve a problem that the operation (the change) of each outrigger is performed only by the determination of an operator in a conventional outrigger device, and each outrigger cannot completely avoid any unexpected action (simultaneous different actions by the specified outrigger and by other outrigger). <P>SOLUTION: A lever interlocking guide 7 having two lever butting members 71, 72 across change levers 56, etc. of slide/jack selection means 5A-5D longitudinally in their operating direction is installed in a displaceable state in the change lever operating direction. The space of the two lever butting members 71, 71 is set to be a value in which the change lever 56 is only operated in a range to each neutral zone from the slide operation side end position and the jack operation side end position, and the lever interlocking guide 7 prevents any outrigger operation while the slide/jack selection means 5A-5D are in the dissimilar selection state. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
