Letting the length from the third load detector 3c to the front wheel B on the right side be y, then L=x+l 2 +y. Considering the moment balance of the left receiving plate 4a with the upper end of the second load detector 3c as the center, W L・x=W 1・l 1 , thus x=l 1
W 1 /W L =l 1 (W 1 /W 1 +W 2 ). Also, for the right receiving plate 4b, y=l 2 W 4 /W R =l 3 (W 4 /W 3 +W 4 ) from the balance of moments about the third load detector 3c, and therefore L={ l 2 + l 1 (W 1 /W 1 +W 2 ) + l 3 (W 4 /W 2 +W 4 )}, the tread is obtained.
