Design Limit LoadThe applied force, or maximum probable force, that a provision (including its connecting structural members) will be subjected to in its most severe transport environment. For lifting, the design limit load is the static load multiplied by the load factor (LF). For equipment tie down, the design limit load is 4.0 multiplied by the gross weight in the longitudinal direction, 2.0 multiplied by the gross weight in the vertical direction, and 1.5 multiplied by the gross weight in the lateral direction.
