Impact bar is used in the loading area of the belt conveyor to replace the traditional cushion rollers.
It’s designed to absorb impact loading which will dramatically reduce shock and stress loading to the structure.
This results in less wear and tear on your conveyor system,
dramatically improves the efficiency and reduces the maintenance cost.
1. Avoids the damage to the belt through the contact between the bar and surface of belt.
2. The conveyor belt is stressed evenly in the loading area, which will reduce the daily maintenance cost.
It effectively eliminates the spillage or scattering of the material caused by inequality of the stress on the belt.
3. The UHMW polyethylene surface has outstanding sliding properties,
to reduce the frictional resistance to the minimum.
4. Ultra elastic rubber absorbs the impact in the maximum.
5. Each part of the impact bar is closely jointed by hot vulcanization.
6.“T-track” fastening device has different tightening points along the bar and
make the joining strong and reliable, easy to install and remove.
