Crane Girders. The maximum moments and shears in crane gir- 

 ders are found as explained in Chapter X. For small cranes I beam 

 girders are commonly used, and are designed by the use of their mo- 

 ments of inertia. Plate girders are designed as previously described. 

 In designing both rolled and plate girders care must be used to proper- 

 ly support the girder laterally.
