The CTC will have their fall 2012 meeting on 10 October 2012 at the U. S. Steel – Midwest Works Training Center. Included in the meeting will be a tour of the U. S. Steel – Midwest Works, and the meeting is being co-located with the AIST Midwest Chapter Kickoff Dinner on 9 October 2012.

The Cranes Technology Committee (CTC) held its winter meeting in the Valley of the Sun in Phoenix, Ariz. The highlight of the meeting was the opportunity to visit the CMC Steel Arizona facility in Mesa, Ariz. The meeting was held on 7 February 2012 and began with the introductions of those in attendance. Following the AIST Antitrust Guidelines and AIST staff announcements, a roundtable discussion was held to review any safety incidents in the industry and to discuss any new safety techniques or technologies. Mike Urbassik, CTC chair, then asked that the champions of the Crane Innovator of the Year Award candidates present their cases for their nominations. Charlie Totten spoke about Mike Einhorn and his “Lifeline Design and Installation at ArcelorMittal Burns Harbor.” Bill Wagner championed Justin Mulch and his “Eddy Current Inspections of Gearing” technology. Totten also championed Ivar Horst, who has made many advancements in “Safety Technologies for Cranes.” Mike Urbassik nominated Bill Vanni and his “Mill Bay Crane Runway Upgrade” project, as well as Rob Loomis’ “Advanced Control Technology for Industry Cranes.” Each member in attendance voted for their candidate and the winner was announced. The winner will be notified and requested to present their paper at the 19th Annual Crane Symposium. The Crane Symposium program was reviewed and presenters were confirmed. Any presentation slot in which the originally invited presenter declined to present was filled by a volunteer from the committee. Urbassik then led a review of the planned updates for Technical Report Nos. 1, 6, 7 and 11 to ensure that the content in each report will be current with today’s practices. He also reviewed the status of the Maintenance, Inspection and Repair Guide for EOT Cranes. A call was placed for any new discussion items and a plaque of appreciation was given to John Patterson and John Filetti of CMC Steel Arizona for hosting the committee tour and attending the CTC meeting. Following lunch, the members traveled to the CMC facility and were greeted by Mike Taylor, John Patterson and John Filetti. The members received a tour of the first operating micro-mill in the world. The facility utilizes a Consteel furnace to melt 40-ton heats, which are treated at the facility’s LRF station. Following treatment, the ladle is sent to the continuous caster, which casts a single billet that is continually fed into an induction furnace and rolling stands before the strand is cut and the rods produced are bundled. Typical operation sees the strand being unbroken from the caster to the final cut line. Products from CMC Steel Arizona are construction-grade reinforcement rod and T-post for fencing. The next CTC meeting will be during AISTech 2012 on 7 May 2012 in Atlanta, Ga., and the committee will meet again immediately prior to the 19th Annual Crane Symposium on 10–12 June 2012 in Pittsburgh, Pa.
