Which ASME volume should be referenced for hand signaling a tower crane?

The correct reference for hand signaling a tower crane is found in ASME B30.3, which specifically covers "Traversing Cranes." This volume includes guidelines and standards pertinent to the safe operation and signaling of tower cranes, as they are a type of traversing crane that requires careful coordination between the operator and the signal person.

ASME B30.1 deals with general hoisting and rigging standards, but it does not specifically address the nuances of signaling for tower cranes. ASME B30.5 focuses on mobile and locomotive cranes, which are different in their operation and signaling protocols compared to tower cranes. ASME B30.7 discusses lift cranes, yet it does not cover the specifics related to hand signaling for tower cranes. Understanding these distinctions is crucial for ensuring safety and effective communication on construction sites involving tower cranes.
