摘要： A positioning system, for a boom having right and left boom arms, comprises: a first actuator for moving the right boom arm relative to a support frame; a second actuator for moving the left boom arm relative to a support frame; a first hydraulic link between the first and second actuators; and a hydraulic control device for controlling movement of hydraulic fluid within the first hydraulic link, thereby controlling extension and/or retraction of the first and second actuators.
