The present invention relates to a safety belt attachment attached to a single tube pipe for safety belt attachment suspended from a pipe hanger.

When working on top of vehicles such as tank trucks or in high places with scaffolding for construction work, etc., workers should wear safety belts and hang from above to prevent accidents such as falling. The work is performed with the hook of the safety belt attached to the equipment such as the lowered existing pipe (see Patent Document 1). In this way, field workers wear safety belts to prevent them from falling from vehicles or scaffolds, enabling them to work safely in unstable places or high places.

Now, there are various types of existing single pipes installed at work sites. For example, there is a type in which struts suspended from the top as described above are connected to the pipe at predetermined intervals. In the case of such an existing single pipe pipe, when a worker attaches a safety belt hook and performs work involving movement, the safety belt hook is attached along the existing single pipe pipe in places where the strut is not connected. Although it can be moved as it is, it is necessary to remove the safety belt hook once at the point where the strut is connected, reattach it to a position beyond the connection point of the strut, and move it.

In this way, when working with a safety belt hook attached to an existing single pipe that is suspended from above via a support, not only does smooth movement become impossible, but the work involves removing the safety belt hook once. Therefore, sufficient safety cannot be ensured.
