<p><P>PROBLEM TO BE SOLVED: To automatically correct a detection error in a rotational position of a cargo handling frame, which can be caused by a change with time. <P>SOLUTION: This container cargo handling vehicle includes a stroke sensor 72 for detecting a stroke quantity S2 of lift cylinders 35 and 36 on the assumption of including the cargo handling frame 34 and the lift cylinders 35 and 36, and a control part 70 for stopping extension operation of the cylinders 35 and 36 by detecting that the stroke quantity S2 of the cylinders 35 and 36 reaches a set value based on an output value of the stroke sensor 72 in the extension operation of the lift cylinders 35 and 36. The control part 70 corrects a reference value on the output value of the stroke sensor 72 (ST64) when detecting a floor landing state of the cargo handling frame 34 (ST63). <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
