If you examine many devices actively utilized in construction operations, you will see, while perfected with centuries of innovation and a comprehension of modern physics, numerous components and instruments that fundamentally match their alternatives in antiquity. Slings, hooks, and lifts—these are mechanisms common as far back as Ancient Egypt, the advent of civilization, and even the Stone Age that today aid the construction of modern structures. However, these items do not encapsulate the entirety of construction equipment. Sometimes you need a little more power, and for this reason, we have mobile and locomotive cranes.
Mobile and locomotive cranes are essentially just cranes powered by internal combustion engines or electric motors, and they are the focus of ASME B30.5-2018: Mobile and Locomotive Cranes. Some common types of mobile and locomotive cranes used in construction include commercial truck-mounted cranes, crawler cranes, locomotive cranes, and wheel mounted cranes (with either a single or multiple control stations).
ASME B30.5-2018 is technically a volume of the overarching ASME B30 standard, which dates back one century and has long been referenced and depended upon for safety guidance on cableways, cranes, slings, and similar lifting devices used in construction. This volume, however, exists as its own document and American National Standard. It applies to crawler cranes, locomotive cranes, wheel-mounted cranes, and variations of the three.
For these cranes, ASME B30.5-2018 digs into a range of concepts, including their construction, inspection, testing, maintenance, and operation, and it details a great deal of supplementary information with figures that can be useful for users of these machines. ASME B30.5-2018 revises the 2014 edition of the same standard, so some of this information has been altered.
Notably, the section on crane operation in the vicinity of electric power lines has been changed in its entirety. Furthermore, ASME B30.5-2018 features a new section on rigger responsibilities, 5-22.214.171.124. This section lists the minimum actions to be taken by riggers assigned to a load-handling activity.
Please note that “side boom tractors and cranes designed for railway and automobile wreck clearance, digger derricks, cranes manufactured specifically for, or when used for, energized electrical line service, knuckle boom, trolley boom cranes, and cranes having a maximum rated capacity of 1 ton or less” are excluded from the ASME B30.5-2018 standard.
ASME B30.5-2018 is available as part of the following standards packages:
- ASME B30.5 / ASME B30.20 / ASME B30.9 – Mobile and Locomotive Cranes Package
- ASME B30.5 / ASME B30.22 / ASME B30.26 – Cranes Package
- ASME B30. Construction Package
ASME B30.5-2018: Mobile and Locomotive Cranes is available on the ANSI Webstore.
