Abstract

See full text

An actuator system for a machine includes a hydraulic actuator connected to a dipper of the machine, and a hydraulic system fluidly connected to the actuator and configured to selectively direct fluid to the actuator. A component of the hydraulic system is mounted on the dipper. The system also includes an overcenter link coupled to a door of the dipper and biased to maintain the door in a closed position. The actuator is operable to move the overcenter link in a first direction, thereby transitioning the door from the closed position to an open position.
