The new ASME B30.3 2012 Edition, “Tower Cranes,” has just been released and can be purchased now from Document Center Inc. ASME B30.3 is used for tower cranes that are powered by electric motors or internal combustion engines. These types of cranes adjust their operating radius by means of a luffing boom mechanism, a trolley traversing a horizontal jib, or a combination of the two.
ASME has been publishing standards on construction cranes since 1916. This particular standard was first released in 1975. Since the last edition in 2009, the standard has covered both construction and permanently mounted tower cranes.
ASME B30.3-2012 includes major changes and additions to the scope of work for erecting, dismantling and climbing tower cranes, as well as new consideration of the impact of wind zone regions across the United States.
Strength and stability requirements have been changed to conform with EN 14439, and the inspection section now includes requirements for “Major Inspections” (to be conducted at 60 month intervals.)
The committee notes that this is a complete re-write of ASME B30.3-2009 and includes many new subjects and requirements that have been updated to reflect the changing work environment in which tower cranes operate. If you use this standard, you’ll want the new edition right away.
