Abstract
A hydraulic system () and method for reducing boom dynamics of a boom (), while providing counter-balance valve protection, includes a hydraulic cylinder (), first and second counter-balance valves (), first and second control valves (), and a selection valve set (). The selection valve set is adapted to self-configure to a first configuration and to a second configuration when a net load () is supported by a first chamber () and a second chamber () of the hydraulic cylinder, respectively. When the selection valve set is enabled in the first and second configurations, the second and first control valve may fluctuate hydraulic fluid flow to the second and first chamber, respectively, to produce a vibratory response () that counters environmental vibrations () of the boom. When the selection valve set is not enabled, the first and second counter-balance valves are adapted to provide the hydraulic cylinder with conventional counter-balance valve protection.
