<p><P>PROBLEM TO BE SOLVED: To provide an introduction evaluation system of a cargo conveying machine capable of objectively and rapidly selecting the introduced model by indicating the reduction of the working burden of a worker associated with the introduction in a comparative manner with a case in which a cargo is conveyed only by a manual work of the worker when introducing the cargo conveying machine capable of moving the cargo in a three-dimensional manner. <P>SOLUTION: The burden on a waist is compared by lumber spinal disc pressure and indicated in N(Newton). The tolerant value is generally 3, 400N. In the graph, the computed value corresponds to a shadowed portion. The lumber spinal disc pressure in the manual work is 3, 545N, and exceeds the general tolerant value of 3, 400N, and it is determined that this work is not suitable for the manual work. On the other hand, the lumber spinal disc pressure in the by a luggage conveying machine 2 is 1,854N, and within the general tolerant value of 3,400N. It is thus determined that the work is suitable for the work using the cargo conveying machine 2. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
