Abstract: Disclosed is a device for spreading liquid and/or solid active agents as well as a method for controlling the device. The device comprises a carrier vehicle, at least one boom arranged pivotably about a rotation axis, and at least one sensor arrangement for detecting an angular velocity and/or an angular position of the boom about the rotation axis in relation to a reference plane. A control unit processes output signals of the sensor arrangements to control signals for an actuator for the purpose of pivoting the boom. Two actuators or a double acting actuator provide an actuating connection between the carrier vehicle and the pivotable boom, wherein the actuator has one active actuating side for each of the two pivoting directions of the boom, which active actuating side is electromagnetically or electromotively actuatable.

Abstract: A device for spreading liquid and/or solid active agents comprises a carrier vehicle, at least one pivotable boom, and sensors for detecting an angular velocity and/or an angular position of the boom. A control unit processes output signals of the sensors to control signals for an actuator to adjust the boom. The actuator produces an actuating connection between the carrier vehicle and the pivotable boom, and has one active pressure side, which is engageable by fluidic actuating pressure, for each of the two adjustment directions of the boom. An approximately equal pressure prevails on the active pressure sides of two actuators operating in opposition or of a double-acting actuator, respectively, when the boom is stationary or moves only slightly in relation to the carrier vehicle. A defined differential pressure is adjustable between the active pressure sides of the two actuators or of a double-acting actuator, when the boom is shifted.
