Mobile crash barrier system to border roads in construction sites or dangerous places; has individual parts narrowed at one end, to overlap when connected and can be connected with single pipe or key

摘要

The system has only one pipe (or key) to connect individual system parts. The individual parts overlap each other for about 20 cm. The material thickness of one end of each part is made thinner on one side, and may be conical, while the other end keeps the profile shape, so that when the thinner end of one part is inside the other end of the another part there are no sharp edges or overriding parts.
