Claims

[Scope of Claim for Utility Model Registration] 1. In a vehicle ladder device that is attached to the side wall of a cap of a large vehicle such as a trailer truck or a dump truck, bending portions are formed oppositely at the upper and lower portions of the ladder body, and the upper and lower Shafts are installed vertically and coaxially at right angles to the bent part, these shafts are rotatably supported on the cab ceiling wall and the underside of the cab, and a space is provided at the back of the cab in which the ladder body can be rotated and stored. A vehicle ladder device characterized in that: 2. Utility model registration claim 1, characterized in that a straight line connecting the angle formed by the rear wall of the cab and the side wall of the cab and the center of rotation of the ladder body intersects with the rear wall of the cab at an angle of 45 degrees or more. A ladder device for vehicles. 3. The vehicle ladder device according to claim 1, wherein the cross-sectional shape of the ladder main body along the side wall of the cab is formed into a prestigious arc shape with the radius of rotation of the ladder as the curvature. 4 A limit switch is provided to detect whether the ladder body is in the retracted position, and a limit switch and a lamp are installed to detect the operation of this limit switch and the handbrake.
A vehicle ladder device according to claim 1, which is a utility model and is characterized in that a warning means such as a buzzer is connected to a power source in series.
