ABSTRACT:
A fork positioner, usable alternatively either as an attachment to an existing load-lifting carriage with forks, or as part of the original equipment of a load-lifting carriage, has a pair of elongate hydraulic piston and cylinder assemblies mountable in an interconnected parallel relationship between an upper transverse fork-supporting member and a lower transverse member of the carriage. Each of a pair of fork-positioning guide members has a fork-engagement surface movable by a respective piston and cylinder assembly and connectable thereto so that the fork-engaging surfaces face substantially perpendicularly away from an imaginary plane containing the respective longitudinal axes of the piston and cylinder assemblies. An exemplary carriage mounting the fork positioner is also disclosed.
