It is an automatic aligning system of conveyor belt to keep the conveyor belt from horizontally escaping from its track and prevent it from moving up and down (rolling) due to the long length of belt during belt movement.

1. As it is impossible for foreign substances to enter the main axis, it does not have sticking problem.
2. As connecting axis is specially designed, there is no shaking in the rotating base.
3. Return roller bracket and guide roller bracket is integrative.
4. As return roller applies the recovering device that moves up and down, there is no problem with ore
  intruding between belt and base.
5. As it is supposed to install on the upper part of the belt, it can be installed without mobilizing any
  equipment.
6. It can repress the rolling of the belt with a roller that puts pressure on the upper side of the lower belt.
7. It prevents early erosion of return roller while enabling stable carrying out of portage.
8. It also prevents belt from skewing by friction between belt and pressure roll.
