  • System and method for controlling shakability of a work tool
    Patent number: 7467514
    Abstract: A system and method for controlling shakability of a work tool. A series of input commands from a control unit to the hydraulic pump cause the hydraulic pump to cycle between a first displacement (maximum) at a first rate (maximum) and a second displacement (zero) at a second rate (less than maximum), within a predetermined frequency. Ultimately, the hydraulic pump remains in a partially upstroked position at the beginning of every cycle. Accordingly, within a small fraction of time after upstroking, the pump is capable of providing full flow to the actuators, resulting in much faster response and movement of the actuators, and therefore improved shakability of the work implement.
