Cut the belt 15 meters below the belt tensioning counterweight and pull the broken end of the old belt out of the window of the belt tensioning counterweight room. The new belt is firmly connected with the old belt broken end with the iron clip, and the other old belt broken end is stuck with the winch wire rope. Slowly pull the winch wire rope until it is taut, release the clip on the old belt, continue to pull the winch wire rope, the old belt is pulled down, at the same time, the new belt is also brought to the large Angle belt conveyor.
