CMAA has added a minimum number of hours of relevant work experience required for crane service technician qualifications. Similarly, it has added a minimum number of hours of work experience as a crane service technician required for crane inspector qualifications. Both of these roles now require a measurable amount of related work experience rather than a subjective statement. For example, a crane technician and crane inspector should have a minimum of 2, hours of relevant work experience and training related to maintaining, inspecting, servicing, repairing and modifying cranes.

CMAA has also added a new table that shows a thorough list of pre-shift inspection items, added a root cause analysis guideline and the CMAA runway alignment chart from Specification Nos. Summary of the requirements of both Inspectors and Crane Technician include: A minimum of 2, hours of relevant work experience and training related to cranes and the ability to identify deficiencies and make repairs to mechanical, structural, and electrical crane components and associated hoisting equipment.

In addition, there are minimum physical and work capability requirements that include communication, vision, hearing, health and medical - that are detailed within the standard. The training requirements include formal training in their area of expertise and trade skills such as basic electricity and wiring practices, basic mechanical principles, machinery alignment, rigging, etc.

In addition, they must have received proper training on safe operating practices of cranes; manufacturer-specific training on troubleshooting and repair of components, job site safety, use of tools and equipment and job site communication and conduct.

Inspectors must receive training on the relevant codes and standards and receive documented inspection training at least every two years to ensure that they stay up with changing codes and standards.

Documented written and practical testing is required to ensure that the technicians and inspectors can demonstrate competence.


Overhead Crane Inspector & Technician Standards

The newly revised specification has six sections including: general information, technical qualifications, jobsite safety guidelines, crane inspection and maintenance, genuine OEM factory parts, and crane service classifications. CMAA representative Dan Beilfuss had this to say: Spec 78 was written with a primary purpose to recognize overhead traveling crane service and the service for associated hoisting equipment, as an industry worthy of having guidelines and standards for providing high quality, professional services performed by safety-minded, manufacturer-trained and certified technicians. Most of the revisions are to a document published in , where the CMAA added a minimum number of hours of relevant work experience required for crane service technicians. The CMMA also concluded that crane inspectors must work a certain amount of hours as crane technicians before they begin inspecting overhead cranes. Now, both of these roles have a concrete number of related work experience hours that candidates must complete.


CMAA Changes Specifications for Overhead Crane Services

It was founded by leading crane manufacturers of the day, to promote standardization, uniform quality and performance throughout the industry. That specification has become the internationally recognized as CMAA Specification 74 last revised and published in along with other Specifications. Since that time, the member engineers of CMAA have continued this heritage with the same original interests. This effort requires a coordinated effort to stay in touch with technology, manufacturing and commercial changes affecting not only the overhead crane industry, but industry in general with an enhanced view towards safety. A full list of related organizations can found in the Scope Section under General Specifications. The Engineering organization formally meets twice a year and is further divided unto Mechanical, Electrical and Structural committees each with its own Chairperson, Assistant Chair and Secretary.
