For the bulk goods wagon Facnps, we have developed, manufactured and supplied a pneumatic control and pneumatic gear motor for opening and closing the discharge valves. Our gearbox ensures a ra pid emptying of the wagon. To enable precise dosing of the bulk goods during loading and unloading, the discharge slides can be opened and closed with self-inhibiting rack-and-pinion gears. The bulk goods can be discharged onto a conveyor belt without any problem and without overfilling. To make handling easier, the wagon can be operated from both sides. The shift logic we have developed prevents incorrect operation.
