The main rod R may be disposed on the fixed deck G positioned above the first vehicle deck D-1, the second vehicle deck D-2, and the N-th vehicle deck DN. have.

The fixed deck (G) is a deck fixed to the hull without being lifted, and the first vehicle deck (D-1), the second vehicle deck (D-2) , and the N-th vehicle deck (DN) are to be transported. It is a deck that can be moved up and down according to the total height of the vehicle. The main rod (R) may be implemented as a wire made of a steel wire, or may be implemented as a steel bar or a section steel depending on operating conditions. The main rod (R) has a length corresponding to the length of the deck to be lifted. That is, it is arranged with the length of N vehicle decks.

The actuator (M) moves the main rod (R) forward or backward in the arranged longitudinal direction. The actuator (M) may be implemented in a form in which a motor and a gear are combined, or may be implemented in a hydraulic cylinder form so that the loaded shaft directly pushes or grabs the main rod (R). The actuator M can be appropriately selected from among various methods according to the weight of the vehicle deck to be lifted in addition to the example shape.
