The following are guide specifications for crane-supporting steel structures:
Field failures often result not from bad calculations but from poor detailing. The 4th edition adds:

Always verify that any article or summary you use references the 4th edition (2021) – earlier editions (3rd ed., 2012) do not include the latest fatigue provisions or AISC 360-16 updates. It includes a dedicated section focusing on cranes
It includes a dedicated section focusing on cranes with guide rollers.

Serviceability often governs crane runway design over strength criteria. Excessive deflections cause the crane to bind, slip, or experience severe vibrations. The design guide outlines strict deflection limits: Crane Class Typical Deflection Limit Light to Moderate (A, B, C) L/600 to L/800 Vertical Heavy to Severe (D, E, F) Horizontal All Classes 5.
