그러나, 종래의 옹벽작업을 위한 사다리는 주로 옹벽의 내측 방향에 설치하고, 갈고리 형태의 걸림부가 옹벽의 윗면에 걸쳐지는 형태로 사용되어 작업자가 옹벽의 외부를 작업하기 위해 옹벽을 넘어갈 때, 몸의 균형을 유지하기가 쉽지 않고, 불안정한 자세를 취할 수밖에 없기 때문에 옹벽을 넘어가는 과정에서 안전 사고가 발생가 우려가 높다.However, conventional ladders for retaining wall work are mainly installed in the inner direction of the retaining wall, and hook-type hooks are used in the form of hanging over the upper surface of the retaining wall. It is not easy to maintain balance and you have no choice but to take an unstable posture, so there is a high risk of safety accidents in the process of going over the retaining wall.

또한, 옹벽의 높이나 폭이 달라질 경우, 달라진 규격에 맞는 다른 사다리를 사용해야 하기 때문에 호환성이 떨어지는 문제점이 있다.In addition, when the height or width of the retaining wall is changed, there is a problem of poor compatibility because a different ladder that meets the different standards must be used.

따라서, 옹벽을 넘어서 건물 외벽 작업을 해야 하는 작업자가 안전하고, 용이하게 옹벽 작업을 수행할 수 있고, 옹벽의 높이 또는 옹벽의 폭이 달라지더라도 호환적으로 사용할 수 있는 사다리가 필요하다.Therefore, there is a need for a ladder that enables workers who have to go over the retaining wall to work on the outer wall of the building safely and easily, and that can be used interchangeably even if the height or width of the retaining wall is changed.
