Abstract
A fork positioner is mounted on a side-shifting carriage of a forklift truck and has transversely-movable, powered yoke assemblies for detachably engaging the upstanding portions of the forks and selectively moving them transversely toward and away from each other while they are supported by the upwardly-facing surface of the fork-supporting member of the side-shifting carriage. The fork positioner has a frame connected to the outwardly-facing, opposed transverse ends of the carriage fork-supporting member in rearwardly-overlapping relation thereto, so that neither the frame nor the fork-engagement structure of the fork positioner protrudes forwardly beyond the forward extremities of the upstanding portions of the forks, thereby minimizing the forward protrusion of the fork positioner beyond the front axle of a counterbalanced lift truck and thus maximizing its load-carrying capacity. The powered yoke assemblies include a pair of inverted U-shaped assemblies which fit over the tops of the upstanding portions of the forks, engaging the opposed transverse sides thereof in rearwardly-overlapping relation thereto. Despite such overhanging engagement of the forks by the U-shaped assemblies, the U-shaped assemblies engage the transverse sides of the upstanding portions of the forks at an elevation below the upwardly-facing fork-suppporting surface of the fork-supporting member of the side-shifting carriage.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
