  • Patent number: 5820180
    Abstract: The present invention is an adjustable multi-purpose lifting apparatus for lifting ties, logs and the like. This invention consists of a fulcrum member having a lever handle integrally attached to a rotational gripping clamp and a second and opposing static gripping clamp connected by a telescopic horizontal structural member, such that when a workman places the tie, log or other object between the gripping clamps and exerts an upward lifting force, the apparatus automatically closes tightly against an outside surface of the tie, log or other object for easy and safe lifting and transportation. A button spring mechanism allows the telescopic horizontal structural member to vary its length and to lock onto a given width of the tie, log or other object. A release grip allows the load to be readily disengaged.
