| 20110048580 | Single cylinder hydraulic log lifter - This invention adds a very large (24×32 inch or larger) log table permanently mounted to the log splitter. This alone adds immeasurably to the efficiency and convenience of splitting. It allows for the true, convenient, and safe one-man operation of a splitter because it catches and stores the far side of the log and log pieces while the operator is free to handle the near side with one hand and the control valve with the other hand. The log lifter is powered hydraulically with the same cylinder, control valve, hoses and fittings that power the split wedge. Very simply, a cable and a pulley are used to direct the force of the existing cylinder to raise the log lifter. This simplicity lowers the cost of the log lifter considerably and makes it and the log table and the convenience of splitting in a more comfortable, standing position more readily available to the splitting public. | 03-03-2011 |
