Abstract
The invention provides a system for regulating pressure equalization in hydraulic mechanisms to suppress oscillation in heavy equipment. The system includes a first and second hydraulic lines, a crossover valve in communication with each of the first and second hydraulic lines, a timing system in communication with the crossover valve, and a motion detector in communication with a heavy equipment component. The motion detector senses a linkage motion and operatively opens the crossover valve, which remains open as directed by the timing system.
