PURPOSE:To contrive automation by providing the input of a desired excavating angle to perform arithmetic on the grounding angle of a bucket to an excavating plane, and by selecting automatic plane excavation when the grounding angle is larger than a specified value, and automatic plane shaping when the angle is smaller than the value, respectively. CONSTITUTION:The point 0 of an oil-pressure shovel main-body is provided with an inclination meter 4, and the pivot A of a boom 1 is provided with a rotational angle detector 5, and the pivotally fitting point B of the boom 1 and an arm 2 is provided with a rotational angle detector 6, and the pivotally angle detector 7, respectively, and the input of detected angles theta0-theta3 to a controller is provided. After that, by an operator, a desired excavating angle theta is set, and the bucket 3 is earthed, and by the controller, arithmetic is performed on the grounding angle. Then, the grounding angle is compared with a set value, and when the grounding angle is larger than the value, then automatic plane excavation is selected, and when the angle is smaller than the value, then automatic plane shaping is selected, to be automatically controlled. Accordingly, work can be automatized, and the work of the operator can be reduced. |
