Is the height of the ladder platform railing 1.2m in terms of the total height, or is it 1.2m above the level of the platform (when the platform height is greater than 20m)?
I don’t understand what you mean. Generally, it is stipulated that when the height of the platform exceeds 20 meters, the height of the guardrails must be no less than 1.2 meters, meaning that the guardrails should extend 1.2 meters above the surface of the platform.
The height exceeding the platform is 1.2m
It refers to a height of 1.2m above the platform.
The footrest is 1.2 meters higher than the platform steel plate or grid at that location; use your own judgment to figure it out. What’s the use of putting it in a pit or under the ankles?
The guardrail – it only serves a purpose when a person is standing on the platform, above the platform’s grating or patterned panel.
Super-platform design, so that people are safe when standing on the platform
It should be 1.2 meters above the platform surface
Learned it – over 1200MM on the platform
