ABSTRACT:
A log splitter with automatic overload protection that prevents the log splitter structure from being damaged by accidental overload. A low-mass rapid-response pressure relief valve is incorporated in the pump side of a hydraulic jack, which produces the splitting force, so that the pressure that can be applied to the jack plunger is limited, but the load that can be supported by the jack is not so limited. The hydraulic jack has applications apart from the log splitter.
