BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cab ladder, and more particularly, to a cab ladder which is not limited by its installation position so that it can be installed while avoiding a cargo area of a ship.

Generally, a ship is equipped with a ladder-type ladder that allows a crew member such as an operator or a crew to board a ship when the ship is docked at the pier.

On the other hand, when the cargo handling ladder system is installed in the cargo handling area of the ship, it is possible that the cargo carrying ladder is loaded on the ship when the ladder is hoisted using the ladder system, there is a problem.

In order to solve such a problem, Korean Patent Registration No. 10-1230966 discloses a conventional cab ladder device having a protection plate.

Hereinafter, a conventional underpass and underpass ladder will be described with reference to the drawings.

FIG. 1 is a view showing a state where a conventional underpass and underpass ladder are lowered to a quay.

Referring to FIG. 1, a conventional underground / underwater ladder system 1 is installed in a ship 2 and includes a first axis line X extending long as a center axis and a first axis line X as a center axis An upper platform 13 fixed to one side of the spindle 11 and extending in the direction of a second axis line Y perpendicular to the first axis line X, And a protection plate 14 for protecting a caterpillar using the ladder 12 from a falling object falling from the ship 2. The lifting ladder 12 includes a lifting ladder 12,

One end of the protection plate 14 is fixed to the spindle 11. The lower end of the lifting ladder 12 is lifted by the ladder 12 around the first axis line X by the rotation of the spindle 11 in one direction, When the elevating ladder 12 is lifted up, the elevating ladder 12 is rotated about the first axis line X by the rotation of the spindle 11 in the opposite direction 12 and is vertically erected on the upper deck inside the ship 2 and stored.

On the other hand, the conventional cab ladder device 1 has a problem that it is not possible to securely protect the walkie-talkie from the falling objects using the protection plate 14. That is, since the weight of the cargo to be loaded on the ship 1 is heavy, there is a limitation in safely protecting the landing gear from the fallen object only by the protection plate 14.

In order to solve such a problem, it is preferable to install the cabin ladder device 1 avoiding the cargo area of the ship. However, the conventional cabin ladder device 1 has a long length, There is a problem in that there is a limit to be made.
