Abstract
A bi-directional log splitter having at least two stationary splitting wedges and a moveable ram therebetween for splitting wood, said splitter being mounted on a trailer where the splitter exerts a substantially equal force for both the exertion and the retraction strokes to increase the production of split wood.
Claims18
A bi-directional log splitter, comprising:
- a trailerable wheeled frame having a main beam along its longitudinal axis with an upper surface for supporting a log thereon;
- a pair of bi-directional equal force hydraulic log splitting cylinders horizontally oriented on said frame, wherein the extension force is substantially equal to the retraction force of each of the cylinders;
- at least two stationary splitting wedges permanently secured to the upper surface of the wheeled frame, said splitting wedges having the wedges facing toward each other and being oriented horizontally for applying pressure to logs that are urged thereagainst and being arranged to split logs;
- a bi-directional horizontally moveable hydraulic ram attached to the pair of hydraulic cylinders for movement in both directions between the at least two splitting wedges, and depending on which direction the cylinders are directed, said ram advances the logs toward each of and between the splitting wedges by the extension and retraction of the attached hydraulic cylinders in order to effect log splitting in both directions;
- and
- a guide structure having a pair of guide rods directing the pair of hydraulic cylinders to operate in a proper orientation.
