A smart door apparatus may include an actuator and a harness. The actuator may be installed at a door rotatably connected with a cabin of the construction machine via a hinge mechanism. The actuator may be configured to operate a locking apparatus of the door by signals of a smart key. The harness may be arranged in an axial direction of the hinge mechanism to supply electricity to the actuator. Thus, only torsion may be applied to the harness regardless of rotation angles of the door to increase a lifespan of the harness.
