Description

SAFETY CAGE AND SAFETY LADDER SYSTEM HAVING THE SAME

The present invention relates to a safety cage and a safety ladder system comprising the same.

In general, the ladder is an auxiliary means of movement used when moving up or down a high place, and allows the worker to move easily and quickly between various types of facilities having a height difference.

The ladder consists of a pair of longitudinal supports arranged in parallel with each other at predetermined intervals with a predetermined length, and a plurality of horizontal connecting bars fixedly installed at predetermined intervals along the longitudinal direction therebetween.

However, in the case of the conventional ladder, the operator repeats the step of stepping on the foot holding the horizontal connecting bars installed between the vertical supports, and in the process of moving to the target position, missing the ladder holding the hand or stepped off the foot Falling accidents will occur. Accordingly, various types of safety ladders have been proposed to prevent falling accidents that may occur in the process of moving using a ladder.

However, conventionally proposed safety ladders have disadvantages in that they are not suitable for use in high-rise places or the installation of safety ladders is not easy due to the complicated structure of the safety ladders.

Therefore, there is a demand for a technology that can effectively prevent accidents of workers and to easily use a ladder.
