Abstract
A vehicle stabilizer apparatus having a plurality of hydraulic stabilizer actuators with each actuator having an integral isolation valve effective to enable operation of a sequentially operable device such as a boom cylinder only after ground-engaging feet associated with the actuators have been brought into firm contact with the ground or other supporting surface. Each actuator is mounted for bodily movement between upper and lower positions on an associated vehicle supported mounting pin. The actuator is caused to move to its upper position when the associated ground-engaging foot engages the ground and through a plunger and plunger spring associated with the isolation valve the position of the actuator is sensed. The isolation valve is in a hydraulic circuit to prevent operation of the boom cylinder unless the actuator is in its upper position.
