As a result, the diameter of steel bars is not very big, therefore, reinforced by the exclusive use of the scissors to cut off can be achieved. Steel straightening machine of the main motor, reducer, drum, clutch components and wire rope. This design (steel straightening machine) is the working principle of electric motors to power into mechanical energy, so that the spindle motor rotation speed by the deceleration after me driven rotating drum, so that involved straightening steel wire rope or release.
