ABSTRACT:
A push-pull slipsheet handler for a forklift truck is capable of utilizing the truck's standard forks for load-supporting purposes, while enabling mounting and demounting of the push-pull assembly and forks in unison with respect to the lift truck carriage. The upstanding portions of the standard forks are suspended from a transverse mounting member affixed to the frame of the push-pull assembly at an elevated position. The mounting member has a pair of fork-supporting surfaces positioned in transversely offset relation to vertically pivotable push-pull links, thereby minimizing forward protrusion of the push-pull assembly in its fully-retracted position despite the mounting of the standard forks on the push-pull frame. The construction also permits side shifting of the push-pull assembly and standard forks as a unit relative to the lift truck carriage.
