This machine is a used channel bale press exclusively used for paper, cardboard and foil. The press runs occasionally with one (55 kW) driving motor, two (110 kW) or with 3 motors of 165 kW. Alternatively, the third motor can be connected automatically as a power reserve according to requirements. The press power of 100 t is even possible in case that due to a minor electrical connection only one motor is running. By using this option the press velocity will be slightly reduced, only. Please see our video for better demonstration of the difference regarding press velocities with one respectively two running motors. The machine has been overhauled in our factory and may be visited according to prior agreement.
