Abstract (en)
[origin: EP1191147A1] A cleaning machine (1) has a sieve unit (9) with hydraulic vibration drive (10), for continuous lifting and cleaning of the ballast (5). The advance speed of the machine is regulated dependent upon variations in the operating pressure of the vibration drive. To achieve constant sieve performance, the speed is raised when the drive operating pressure drops, resp. reduced, when the pressure rises. A regulator unit has a pressure transducer to detect the operational pressure, and a servo member to regulate that pressure.
