Abstract
The utility model discloses a safe ladder, which is characterized in that one side of a ladder vertical rod (1) is further provided with a ladder handrail (4), and the ladder handrail (4) is connected with the ladder vertical rod (1) together through a welding mode. The existence of the ladder handrail (4) leads a staff to be tied on the ladder handrail through a ladder belt when climbing up and down, construction security of staffs is guaranteed, and construction speed is not influenced. The safe ladder can be widely applied in the processing fields such as ladders of electric power and communication steel pipe pole.
Description
Technical field
The utility model product belongs to the cat ladder field of ascending a height of electric power, communication system steel pipe pole.
Background technology
At present, the measure of only ascending a height of the cat ladder of electric power, communication system steel pipe pole does not have safeguard procedures, often has the people to fall reality from cat ladder accidentally, causes security incident.There is the people to adopt cat ladder to protect the cage type formula in the communication field of ascending a height, but the manufacturing process complexity, and the production cycle is longer, and causes the material significant wastage.
Summary of the invention
The purpose of this utility model just provides and is a kind ofly increasing safety rail, do not influencing the safe cat ladder of speed of application.
For reaching above purpose, the utility model mainly is made up of cat ladder vertical rod (1), cat ladder pawl (2), cat ladder connector (3), set up a cat ladder handrail (4) in a side of cat ladder vertical rod (1), cat ladder handrail (4) links together by welding manner and cat ladder vertical rod (1).
By above setting, the utility model increases the cat ladder handrail on the basis of original cat ladder, and personnel can directly tie up to safety belt on the handrail during cat ladder up and down, do not influence speed up and down, have guaranteed the safety of construction, and have effectively saved material.
