PURPOSE:To facilitate the operations of an excavation working vehicle by using a system in which the vehicle is moved by a teaching mode, variation in the angle relations of a slewing base, a boom, an arm and a bucket is memorized, and the vehicle is controlled on memory by command from discharge and return mode operators. CONSTITUTION:A teaching mode operator 16A is actuated, and levers 13a and 13b are operated from a manual actuating point (the first setting position) to a manual releasing operation point (the second setting position) to move a bucket 9. Information of the first-forth detectors 14a-14d to show the varying conditions of manual operation of the levers 13a and 13b is stored in a controller 16. A discharge mode operator 17A is operated and valves V3, V6, V10 and V11 are automatically operated by a controller so that a slewing base 2, a boom 7, an arm 8 and a bucket 9 are at the first setting position. A return mode operator 18A is operated and automatic operation to the second setting position is made likewise by a controller 18. |
