Abstract
A control device includes a bucket control unit and a speed restricting unit. The bucket control unit calculates a control speed controlling a bucket so as to maintain an angle of the work equipment at a constant angle. The speed restricting unit reduces the control speed when the bucket is driven at the control speed calculated by the bucket control unit and when a direction in which the bucket is driven and a direction in which the arm is driven coincide with each other.
Claims8
A work equipment control device for controlling a work machine provided with work equipment including a bucket and an arm supporting the bucket, and provided with a work machine body supporting the work equipment, the work equipment control device comprising:
- a bucket controller configured to calculate a control speed for controlling the bucket so as to maintain an angle of the work equipment at a constant angle;
- and
- a speed restrictor configured to reduce the control speed when the bucket is driven at the control speed calculated by the bucket controller and when a driving direction of the bucket and a driving direction of the arm coincide with each other,
- wherein the speed restrictor determines whether the driving direction of the bucket and the driving direction of the arm coincide with each other.
