Transportable lift truck with telescopic lifting arm

A materials handling lift truck capable of being attached onto the back of a carrier vehicle, the lift truck comprising a generally U-shaped frame;

• a substantially A-shaped gantry structure having two laterally spaced upright assemblies located approximately centrally and rearwardly of the U-shaped frame;
• a motive power unit disposed in an area substantially between the two laterally spaced upright assemblies of the A-shaped gantry structure;
• two front wheels;
• a steerable rear wheel;
• a telescopic arm lifting device having at least one slidable section, rotatably mounted by a shaft between the two laterally spaced upright assemblies of the A-shaped gantry structure such that by activating a lift cylinder the telescopic arm lifting device pivots about a relatively horizontal axis located approximately centrally and rearwardly of the U-shaped frame and approximately above the motive power unit and the rear steerable wheel;
• lifting tines that are mounted on a tine carriage that is rotatably moveable in a vertical plane and supported at the end farthest from the telescopic arm lifting device substantially horizontal pivoting axis;
• an operator's station located on one side of the U-shaped frame and adjacent to the A-shaped gantry structure, wherein the shaft is mounted to the spaced upright assemblies for pivoting about a substantially vertical axis and relative to the spaced upright assemblies so that the substantially horizontal pivoting axis of the telescopic arm lifting device is capable of being pivoted about the substantially vertical axis so as to precisely vary the yaw angle of the telescopic arm lifting device thereby enabling the accurate lateral movement of the lifting tines within a predetermined distance.
