AUTOMATIC ONE LINE GRAPPLE

机译:自动一线抓

摘要

A grapple employed in the logging industry which includes a pair of tongs which are automatically opened and closed while being hung or supported from a single line or support and which is especially useful in highlead grapple yarding. The tongs are opened and closed in a single cycle of operation or a multiple cycle of operation which renders the grapple quite useful in turning or rotating a log. The tongs of the grapple are either supported from a supporting pin and linkage in which position the tongs are in closed or adjacent position or supported from a pin interconnecting the crossed tongs which pivots the tongs to an open position with the supporting function being sequential in response to movement of the grapple in a predetermined manner.
