Rule 2
Use a LNCG setting from Table 3-18, columns (k), (I) or (m) to give N > H and T > G. Both roller beams are in the
low position.
(1)
Using the LNCG settings from Rule 1, choose a setting from columns (k), (I) or (m) (whichever is
allowable from Rule 1) which gives an N greater than H. If none of the choices meet the criterion, choose the highest value
available.
(2)
Check to see if the T value [from Table 3-18, column (n)] is greater than G. If N is less than or equal to
H, or if T is less than or equal to G, proceed to Rule 3.
(3)
If N is greater than H and T is greater than G, the LNCG setting chosen provides adequate nose lift and
the bridge selected has adequate tail clearance, proceed to loads required.
