ABSTRACT:
A lock out for fluid cylinders, such as hydraulic cylinders operating farm machinery, which prevents the supported load from dropping and provides a lock out valve independent of the ordinary control valve used with the cylinder. The lock out unit mounts on the cylinder and within the outer peripheral dimensions of the cylinder. The linear acting valve operates in the same direction as movement of the cylinder itself to provide a compact, directly mounted lock out.
