   The requirements to be satisfied in the design of a gantry girder are that it has to withstand effects due to ______.

   1. Moving loads, impact effects and fatigue.
   2. Moving loads, longitudinal loads, lateral loads, impact effects and fatigue.
   3. Lateral loads, longitudinal loads, impact effects and fatigue.
   4. Dynamic loads, longitudinal loads, impact effects and fatigue.
   Show answer

   Answer: (2) Moving loads, longitudinal loads, lateral loads, impact effects and fatigue.

   A gantry girder must resist the vertical moving wheel loads of the crane with impact, lateral (surge) loads from the crab, longitudinal loads from braking of the crane, and fatigue from repeated load cycles. Only option (2) lists all of these.
