摘要： A ride control system and method where the system includes first hydraulics for equalizing pressure between ride control accumulators and boom cylinder head side, and second hydraulics for providing low pressure drop connection between ride control accumulators and boom cylinder head side. When ride control is engaged, the first hydraulics equalizes pressure between ride control accumulators and boom cylinder head side to within a pressure threshold, then the second hydraulics provides the low pressure drop connection between ride control accumulators and boom cylinder head side. Ride control system can include third hydraulics for providing fluid connection between boom cylinder rod side and tank; where after first hydraulics equalizes pressure to within pressure threshold, then third hydraulics provides connection between boom cylinder rod side and tank. The ride control system can also monitor the condition of the ride control accumulators.

摘要： A fail-safe system and method for an electro-hydraulic system. The system includes a controller, sensor, directional control valve, interlock, hydraulic valve and movement actuator. The directional control valve moves when the controller is moved. The interlock is hydraulically coupled to the directional control valve; and is in active position when the directional control valve is moved, and in shutoff position when the directional control valve is not moved. The hydraulic valve has an input side coupled to a flow source and an output side coupled to a hydraulic function. The movement actuator moves the hydraulic valve to a desired position as directed by the controller when the interlock is in the active position, and does not move the hydraulic valve when the interlock is in the shutoff position. The sensor detects movement of the controller and sends a control signal to the first valve actuator.
