PURPOSE: A rail locking device and a bucket carrying device are provided to reduce the frequency of failures by employing a locking bar shaft, a locking bar, and a stop bar instead of using a hydraulic cylinder. CONSTITUTION: A rail locking device comprises a locking bar shaft, a locking bar coupled to the top of the locking bar shaft by a hinge, and a stop bar coupled to the end of the locking bar. One side of the locking bar is rotated up and down around a hinge shaft by loads applied to the other end. The locking bar shaft comprises a supporting body(11), a locking bar first coupling hole bored through the wall of the support body, a locking bar hinge pin(13) inserted to one side of the thickness of the first coupling hole and protruding from the other side, and an anti-separation nut coupled to the protruding end of the locking bar hinge pin. |
