PURPOSE:To change over a rear dump and a side dump automatically by a driver's seat by fitting a changeover valve next to a dump control valve and interlocking and operating a changeover cylinder and the changeover valve. CONSTITUTION:The lock pin of a dump hinge is operated by the changeover cylinder 2, and the rear dump and the side dump are changed over. The changeover valve 3 is interlocked with the changeover cylinder 2 and changed over. The changeover valve 4 is fitted at the next stage of the dump control valve 1, and operates the changeover cylinder 2. When the changeover valve 4 is positioned at a central position, the changeover cylinder 2 does not operate, and only a lift cylinder operates and executes the rear dump. When the changeover valve 4 is moved left and right, the changeover cylinder 2 operates first and the dump hinge is changed over, and the lift cylinder 10 operates and executes the side dump. |
