Wondering How SuperSplit Log Splitter Works?

After power is turned on (either gas or electric [ A ] ), the kinetic energy is stored in two revolving flywheels [ B ]. These flywheels are firmly secured to a one-piece pinion gear [ C ]. Because of the flywheel weight and RPM, as well as being mounted on ball bearings and secured to the frame, the pinion gear has tremendous power advantage.

To transmit power from pinion gear to log, a rack gear [ D ] is engaged by a cam-lock assembly [ E ]. The rack gear, now fully engaged and locked in the pinion gear, moves out with a 12 to 24 ton force across the log bed [ F ] into the alloy heat-treated steel blade [ G ]. At the end of the full 24” stroke, the rack is spring loaded upward and backward [ H ], which disengages the cam lock and immediately returns to start position.

For safety reasons, the SuperSplit log splitter is a semi-automatic machine. This means every cycle must be manually activated by lowering and raising the operation lever [ J ] that engages the cam-lock; but after activation, the rack will complete a full cycle. The cycle, however, can at any time be interrupted by simply returning the operating lever to the up position. The flywheel will also stall on overload. Successive cycles may be engaged if necessary in order to drive through particularly large, hard or knotty logs. Flywheel recovery time is about 1/2 second. (If you have ever used a rack type arbor press or swung a heavy maul, you will better understand why the SuperSplit kinetic log splitter principle works so well.

Power and Performance

At the core of the SuperSplit HD are two 90-pound flywheels that store an immense amount of kinetic energy. This energy is unleashed via a pusher arm, which, when engaged, forcefully drives wood through a wedge, splitting it efficiently. The action is initiated by actuating a control arm, which in turn moves a rack gear to interact with the flywheels, demonstrating a seamless integration of mechanics for optimal splitting performance.

Design and Durability

The HD model has seen significant upgrades from its predecessors, most notably in its pusher design. It boasts a two-and-a-quarter-inch wide rack gear and a pivoting pusher mechanism supported by four bearings, ensuring minimal space between the pusher plate and the I-beam. This design reduces debris interference and improves the return stroke’s smoothness—a crucial factor in maintaining consistent operation and minimizing maintenance hassles.

Ease of Use and Maintenance
