The invention relates to an electro-hydraulic device for moving a jib for a derricking-jib tower crane, the motor of said device being designed for operation at the average required power. The operating time in an energy-wasting part load range is thus significantly reduced in relation to conventional electro-hydraulic devices for moving a jib.
