摘要： An apparatus for adjusting an orientation of a suspended load. The apparatus includes a frame suspended from a suspension assembly. The suspension assembly has a first pivot axis enabling up and down pitching movement of the frame relative to the suspension assembly and a second pivot axis enabling up and down rolling movement of the frame relative to the suspending assembly. A first actuator extends between the suspension assembly and the frame. When the first actuator expands, a first end goes down and a second end goes up. When the first actuator contracts, the first end goes up and the second end goes down. A second actuator extends between the suspension and the frame. When the second actuator expands, a first side goes down and a second side goes up. When the second actuator contracts, the first side goes up and the second side goes down.
