Abstract
A lift truck fork positioner for respective inner and outer pairs of load-handling forks includes power actuators for selectively extending and retracting the outer pair of forks and latch assemblies for selectively detachably connecting an inner fork fixedly to a respective adjacent outer fork in spaced relation thereto automatically in response to the extension of the outer forks beyond a predetermined inner range of extension. Each latch assembly, when connecting the inner fork to the outer fork, fixedly prevents any narrowing of the spacing between the interconnected inner and outer forks, as well as fixedly preventing any widening of such spacing.
