According to the US Patent and Trademark Office: “A new or retrofit block hoist for conventional, hydraulic-powered log splitters assists in the lifting, maneuvering, and positioning of large diameter, heavy logs that require multiple radial splits to section them for firewood, comprising a boom, pulley and cable system.”
It added: “A boom assembly is secured to the top end of the splitter guide beam and pulleys guide a lifting cable anchored to the wedge slide to a log section retainer means (dog or awl).”
An abstract of the invention, released by the Patent Office, said: “The upward, hydraulically-powered movement of the cutting wedge along the in phase-beam lifts the log section as the wedge is raised into its upward, retracted position. Once lifted, the log is swung into position between the wedge and splitter foot plate. The wedge is then power extended (lowered), splitting the log. An optional turntable is securable to the footplate. The inventive block hoist can be provided as a kit.”
The inventor was issued US Patent Number 7,011,123.
