HOIST CONTROL FOR DUMP BODIES OF HAULING MACHINES
A method for controlling a hoisting mechanism for a movement of a dump body between a rest condition and a raised condition relative to a frame. The method includes receiving a request to vary the dump body between the rest condition and the raised condition; determining a criteria for actuating the hoisting mechanism corresponding to the request, the criteria including an actuation direction and an actuation speed for a fluid actuator of the hoisting mechanism; moving a valve to a predefined position based on the actuation direction to set a direction of movement of the dump body; and controlling a state of the valve in the predefined position of the valve and an operational speed of a pump supplying the fluid flow to the valve based on the actuation speed to set a rate of movement of the dump body along the direction of movement.
INTEGRATED HYDRAULIC STORAGE AND HEAT EXCHANGE
A work machine includes a hydraulic pump in fluid communication with an interior of a support structure. The hydraulic pump is constructed to impel hydraulic fluid stored therein. Work machinery is mechanically coupled to the support structure and operated by the impelled hydraulic fluid.
