ABSTRACT:
A manual forklift for lifting, maneuvering, and arranging palleted freight, comprising an extensible wheeled base, a steering handle, a mast, and a boom with a descending standard secured to a support frame carriage and forward extending tines. Hydraulic jack cylinders joining the mast to the boom and the boom to the descending standard in concert with hinge joints connecting the mast to the boom and the boom to the descending standard allow the tines to be manipulated forwardly or backwardly, raised or lowered, and tilted upwardly or downwardly relative to the mast and base, enabling the user to transfer palleted freight engaged by the tines between surfaces with differing heights and angles and across longitudinal spaces. Castered wheels affixed to the base further enable freight to be moved multi-directionally, including laterally leftward or rightward.
