The invention relates to a device for driving a transfer beam for handling relatively heavy loads, comprising in the case of a beam having a rack rigidly associated therewith. Said device consists essentially of a transmission incorporating between the driving motor and the pinion in meshing engagement with the rack a clutch and a brake both controlled by electromagnetic means, servo means for supplying electric current to each electromagnetic control of said clutch and brake, and a pair of servo-generators adapted to monitor the one the acceleration phase of the transfer beam from the standstill position of said beam and the other the deceleration phase before stopping the beam.
