Abstract (en)
[origin: EP2014835A1] The system has a variable flow hydraulic pump (8) driven by a motor feeding hydraulic fluid to a vibrator or a vibrating system. The vibrating system comprises eccentric weights driven in rotation by one hydraulic motor receiving fluid. An adaption unit is provided for continuous adaptation of rotation speed of a motor (9) of the hydraulic unit (7) in relation to the energy actually consumed by the vibrator (1). The vibrator is provided with a vibration frequency sensor, where the motor of the hydraulic group is a heat engine equipped with a device to measure a load rate.
