Speed bumps IDN-300


The width of such artificial road irregularities is 300 mm, and the height is 37 mm. Such bumps create a relatively small resistance to the movement of the vehicle, which is ensured by the small dimensions of these products. However, the effectiveness of such artificial road irregularities is higher than that of IDN-250.

Application and purpose of IDN-300

IDN-300 are a budget option for artificial road irregularities, which is ensured by a reduced width of the product compared to larger overall IDNs. Similar speed bumps are used for arrangement of parking lots, various adjacent territories, yards, that is, those sections of the road where there is no need to use products that comply with GOST.


Before installation, it is necessary to ensure a smooth surface of the roadway at the place of attachment of the IDN. Next, you need to expand the product sections in one line, tightly and securely connecting them to each other. The number of sections should be determined based on the width of the carriageway, which creates a complete overlap of the roadway. This will avoid a situation where vehicles completely or partially bypass this obstacle. Failure to comply with this recommendation may provoke a sharp increase in the load on certain sections of such a TDDS, which leads to their premature failure. An effective drainage is provided by 0.2 m of free roadbed at the edge of the road, provided that the radius of curvature of the road surface complies with GOST standards.

Next, you need to outline the drilling locations on the served pavement, remove the sections of IDN and perform drilling. After this, install the IDN in place, insert the bolts and tighten them. All mounting holes must be used for the most reliable and high-quality installation.
