Can inverted chain lifting equipment be used in series?
Cannot be used in series! The safety hazard is too great!
Are there any regulatory requirements? ? @book boy
There are many places where series connection is used. The standard specification does not directly state whether series connection is allowed or not. Ignorant people are fearless! But I consider it from the safety factor.: JB 9010-1999 Hand Chain Hoist Safety Rules Standard 3.5 The safety factor of the wire ropes and chains used for hanging and binding should not be less than 6. What is the safety factor when the two are connected in series? It must be less than 6, so it is strictly prohibited!
Can anyone calculate the safety factor after series connection:victory:
Strictly prohibited? If the connection is reliable, the minimum pulling force meets the lifting capacity requirements, and the safety factor meets the standard even if calculated as 1, is it still strictly prohibited? For example, the inverted chain can lift 1 ton, and two groups are connected in series to lift 10kg objects. It’s not a quarrel, it’s just that there are too many things like this at the scene. As long as you calculate it, it'll be fine.
This is an argument: lol Pictures of hand chain hoists should be considered in extreme situations! The safety factor is one? Do you dare to use it?
I'm not trying to argue, I'm just telling you not to be so absolute. Even if you are an expert, try not to overstate your words. Unless you find a basis to say "forbidden"! Also, from now on, stop posting posts like 500 Wealth Posts that no one downloads for a year. Just looking at it makes me want to yell at you. It's summer and I'm getting angry. Please understand.
