The CTC met 7 May 2018, Philadelphia, PA, USA.
The following officers were elected:

  • Chair: Heath Hooker, Nucor-Yamato Steel Co.

  • Vice chair: Mick Foster, Sterling Steel Co. LLC

The CTC met 7–8 February 2018 • Mobile, Ala., USA. The meeting began with a review of the CTC’s AISTech 2018 technical session, which includes five papers. Members in attendance received instructions regarding paper and presentation review, session chair responsibilities and an overview of the AIST Commercialism Policy.
The committee also opened up for nominations to be made for 2018–2019 officers.
Discussion then focused on the 25th AIST Crane Symposium, which will be held on 10–12 June 2018 in Pittsburgh, Pa., USA. A lengthy discussion was held on the remaining open presentation slots.
The CTC has always prided itself on providing a forum for innovation, new technology and helping members/attendees solve their problems through networking and technology exchange. One concept that may be implemented is to have an open-floor discussion where producer attendees can voice an issue to the audience and to let the other attendees provide feedback to the problem. Another concept is to have multiple presentations be made centered around how Industry 4.0 is impacting crane automation. Presentations would include programming for new automated cranes as well as reprogramming older cranes and the lessons learned through experiences.
The committee then heard from the Crane Innovator of the Year champions, who individually spoke on behalf of their nominees. Mick Foster championed the use of drone technology for crane inspection. He touted the technology as a better, safer, cheaper and faster method of doing crane runway and crane structure inspections. The technology could be applied to other structures in industry as well as for crane inspection. Charlie Totten championed the use of rolling glare shield glass in electric overhead traveling (EOT) cranes. The glass would be used in place of the pull-down shades typically used by crane operators to prevent sun glare or to shield a crane operator’s eyes while being exposed to radiant light from molten metal. Liz McCallum championed the study done by Steel Dynamics on crane cab air quality. The study focused on testing the air inside a crane cab and comparing it to the air outside the cab to ensure that the air filtration systems on the crane cabs are properly functioning for the operator’s safety. The last champion, Russ Walters, spoke about the importance of proper grouting techniques for crane rail and runways. The proper grout for the application must be used to ensure proper compressive strength, impact resistance and service temperature so that it performs properly.
The Crane Innovator of the Year Award will be presented at the 25th AIST Crane Symposium. The meeting concluded with an open discussion on member concerns.
One item discussed was for future revisions of Technical Report No. 6 to include additional metric conversions and to include lighter-weight cranes that are not EOT-type cranes such as jib cranes and small maintenance cranes.
The meeting concluded with a tour hosted by Stuart Driskell of AM/NS Calvert. Jim Dunn, general manager of maintenance, welcomed everyone to the AM/NS facility and gave a description of the facility, its production lines and capabilities. Details were provided on the cranes at the facility, their sizes and any particular attributes to the cranes. AM/NS has been automating many of their cranes to reduce maintenance and to increase operator utilization for other areas of production. Some automated monitoring used for crane maintenance are sensors, bearing thermocouples, motor vibration monitoring, anti-collision and the use of GPS tracking.

The CTC met 4–5 October 2017, Memphis, Tenn., USA. The primary focus of the meeting was to review the ballot draft responses from the CTC members for the Technical Report No. 6 revisions.
Following the response review, the CTC held nominations for a replacement vice chair, as the former vice chair had retired from the committee and the steel industry. Heath Hooker, Nucor-Yamato Steel Co., was elected by the members to assume the duties of vice chair.
A brief summary and discussion followed on the organization of the crane session for AISTech 2018. Session chairs were also identified.
Charlie Totten provided an update on the 2nd AIST-IAS Crane Symposium, held in Rosario, SF, Argentina, on 23–25 October 2017. Twenty-nine presentations were confirmed for the event with a mix of North American, South American and European technology for electric overhead traveling cranes.
The CTC nominated individuals for the 2018 Crane Innovator of the Year Award. Champions were selected to promote nominees at the winter 2018 CTC meeting.The meeting concluded with an update and discussion on the 25th Annual Crane Symposium, which will be held on 11–12 June 2018 in Pittsburgh, Pa., USA. Presentation topics are still being sought to fill out the program for this milestone event of the longest-running AIST Technology Training course.
On 5 October, the CTC was hosted by Nucor-Yamato Steel Co. for a tour of its steelmaking and rolling operations.

The CTC met 22–23 February 2017, Roanoke, Va., USA.  The AIST Mechanical/Structural Subcommittee met independently on 22 February 2017 to finalize its revisions to AIST Technical Report No. 6 — Specification for Electric Overhead Traveling Cranes for Steel Mill Service.  Three comments in the mechanical section of the report still require review prior to the report being ready for ballot draft. 
The general CTC meeting occurred on 23 February 2017. An open discussion on crane safety lights was held in reference to a recent article entitled, “Innovative Warning Lights for Mobile Equipment and Overhead Cranes,” which was published in the August 2016 issue of Iron & Steel Technology. CTC members noted the increase in use of lasers and colored lights around mobile equipment to increase awareness. A note was made during the discussion that the brighter LED lights being installed on some crane bridges may cause some operators to experience glaring on the crane cab glass.
The CTC reviewed its AISTech 2017 technical session. A comment was made that outstanding authors who have yet to register should be contacted and urged to fulfill their commitment to the conference.
The 24th Annual Crane Symposium program was reviewed and open presentation slots were filled, bringing the event up to 24 individual presentations on crane technology and case studies.
A discussion was also held regarding the 3rd international and 2nd AIST-IAS Crane Symposium, which will be held in Rosario, SF, Argentina, on 22–25 October 2017. There are 27 presentations from Argentina, Belgium and the U.S. scheduled. 
The business portion of the meeting concluded with the champions of the nominees for the Crane Innovator of the Year Award promoting their candidates to receive the award. Four champions spoke for the nominees and a vote was taken of the members in attendance. The Crane Innovator of the Year winner will present their innovation at the 24th Annual Crane Symposium in June.
