Abstract: A hydraulic system (600) and method for reducing boom dynamics of a boom (30), while providing counter-balance valve protection, includes a hydraulic cylinder (110), first and second counter-balance valves (300, 400), and first and second control valves (700, 800). A net load (90) is supported by a first chamber (116, 118) of the hydraulic cylinder, and a second chamber (118, 116) of the hydraulic cylinder may receive fluctuating hydraulic fluid flow from the second control valve to produce a vibratory response (950) that counters environmental vibrations (960) on the boom. The first control valve may apply a holding pressure and thereby hold the first counter-balance valve closed and the second counter-balance valve open.

Abstract: Systems and methods for auto-commissioning first and second valve assemblies associated with an actuator in an electro-hydraulic system are disclosed. In one method, a controller performs an automatic test protocol to determine a bulk modulus over fluid volume parameter used by the controller to control the valve assemblies. In one aspect, the test protocol can include pressurizing each side of the actuator to two different pressures with one of the first and second valve assemblies and blocking the other side of the actuator with the other of the first and second valve assemblies. The bulk modulus over fluid volume parameter for each valve assembly can be calculated based on recorded fluid pressures at the actuator and consumed flow at the first and second valve assemblies.

Abstract: A mobile application includes a motive power circuit having a power storage device and an electrical load, where the power storage device and the electrical load are selectively electrically coupled through a power bus. The application includes a power distribution unit (PDU) electrically interposed between the power storage device and the electrical load, where the PDU includes a breaker/relay positioned on one of a high side and a low side of the power storage device. The breaker/relay includes a fixed contact and a moveable contact selectively electrically coupled to the fixed contact, where the moveable contact allows power flow through the power bus when electrically coupled to the fixed contact, and prevents power flow through the power bus when not electrically coupled to the fixed contact. The breaker/relay includes an armature coupled to the moveable contact, and capable to open or close the motive power circuit.
