After assembly and testing, first of all the manual operation does work but not as well as we expected. The performance of the belts is not good. There is extension of the belt and slipping occurred while tilting the furnace. Hence the furnace could not controlled very well. But the brake does work properly.
Besides, we found that the clutch cannot move as smooth as expected. The reason is that the unbalance weight of the lever system makes the lever systems pressed onto the clutch. So the lever system cannot slip smoothly. Moreover due to the time overrun and the delay of the components arrived, we have not test the part of motor operation.
