This excavation area limiting control device for construction machinery is provided with a control unit (9) for performing area limiting control by controlling at least one of a plurality of hydraulic cylinders (3a, 3b, 3c) on the basis of the orientation and position of each of a boom (1a), an arm (1b), and a bucket (1c), said control device being provided with an angle detector group (8) that detects the rotational angle of the boom (1a), the arm (1b), and the bucket (1c), and a tilt angle detector group (81) that detects the angle of the boom (1a), the arm (1b), and the bucket (1c) with respect to the ground. The control unit (9) selects a detector to be used in the calculation of the orientation and position of each of the boom (1a), the arm (1b), and the bucket (1c) from the angle detector group (8) and the tilt angle detector group (81), said selection being based on the magnitude of the velocity of at least one of the boom (1a), arm (1b), and bucket (1c). |
