1. A construction equipment, comprising:
a lower traveling body;
an upper rotating body rotatably supported on the lower traveling body;
a work machine which comprises a boom rotatable with respect to the upper rotating body, an arm rotatable with respect to the boom, a bucket rotatable with respect to the arm, and a tilt rotator consisting of a tilting actuator for supporting the bucket to tilt with respect to the arm, and a rotating actuator for supporting the bucket to rotate around a rotating axis of the rotating actuator with respect to the arm;
an operation lever for outputting an operation signal corresponding to an operation amount of a driver;
a location information providing unit for providing location information and posture information of the work machine;
a work setting unit for setting a work area of the work machine, and providing plane information of the work area; and
an electronic control unit for controlling the work machine according to a signal inputted from at least one of the operation lever, the work setting unit and the location information providing unit,
wherein the electronic control unit is configured to make a determination that a rotating operation signal of the bucket lasts longer than a predetermined reference value and to align the rotating axis of the rotating actuator to be vertically aligned in parallel with respect to a normal vector of a planar surface of the work area based on the determination.
