Hydraulic balancing of independently loaded suspension cylinders in an implement.

摘要

A movable implement comprises: a frame and a tool suspended from the frame. The tool has a center lengthwise axis that extends through the center of the tool and parallel to a direction of travel of the implement. The center lengthwise axis defines a first side of the tool and a second side of the tool generally opposite the first side. A first hydraulic lift cylinder is attached to the frame and the first side of the tool. A second hydraulic lift cylinder is attached to the frame and the second side of the tool. A hydraulic accumulator is fluidly connected to the first hydraulic lift cylinder. A control system is provided for controlling a first fluid pressure in the first hydraulic lift cylinder to be less than a second fluid pressure in the second hydraulic lift cylinder.
