  • Log splitter with pressure adjustment
    Publication number: 20080295919
    Abstract: A log splitter is being proposed for splitting a piece of wood into individual logs, with a platform for the piece of wood that is delineated on the axial sides by two stops (4, 5), which are each fitted in the normal direction to the axis of the wood to a holding part (1, 7), whereby at least one stop (5) is hydraulically operable in the axial direction and at least one stop (5) is designed as a splitting wedge. The log splitter is characterized in that a valve (2) is designed in the pressure-sided hydraulic intake cable, with which the oil pressure that drives the movable stop (5) is adjustable, with which at least one stop is movable.
