Always use two or more people to assemble and dismantle a long pipe scaffold. Assembling and disassembling alone is very dangerous. When using a clamp, please use it within the permissible limit of clamp strength to ensure safety. Please be sure to use two clamps, as they are not strong enough to withstand shearing loads due to their structure.

[When scaffolding pipes are supported by only one side, a shearing force beyond expectations acts when force is applied to the end of the scaffolding pipe, breaking the orthogonal joint rivet, and due to its structure, the shearing load is not strong. ] Therefore, unnecessary omission of brackets and braces.
