Abstract
A boom assembly includes a frame, a boom, a boom stabilization cylinder, and a feedback cylinder. The boom is rotatably mounted to the frame to rotate about a first axis. The boom stabilization cylinder is coupled to the boom to resist rotational deflection of the boom about the first axis. The feedback cylinder is coupled to a counterbalancing weight. The feedback cylinder is hydraulically coupled to the boom stabilization cylinder. Movement of the boom stabilization cylinder to resist deflection of the boom causes corresponding movement of the feedback cylinder to lift the counterbalancing weight.
