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.
The Cranes Technology Committee (CTC) held their fall meeting as the guests of Xtek Inc. in Cincinnati, Ohio, on 4 October 2011. Following a welcome introduction to Xtek by Frank Petrek, Xtek vice president, Mike Urbassik, CTC chair, opened the meeting and asked all in attendance to introduce themselves and their companies. The AIST Antitrust Guidelines and the AIST staff announcements were read and noted. The committee discussed potential papers for their technical session at AISTech 2012. The CTC will plan a single, six-paper session for AISTech 2012 that will focus on “EOT Cranes for Heavy Industrial Service.” The members then began planning presentations for the 19th Annual Crane Symposium, which will be held in Pittsburgh, Pa., on 10–12 June 2012. The committee identified 22 potential presentation topics, and members will approach the presenters to secure their commitments for this conference. A potential Brazilian Crane Symposium was suggested. During the AIST Oxygen Steelmaking Technology Committee Brazil Study Tour, the Brazilian steelmakers were approached to gauge their interest in such a conference being held in Brazil. Many saw the value of holding the conference and their input is being solicited to determine the types of technical presentations that would benefit the EOT crane maintenance personnel in Brazil. Committee members also discussed the nomination of a candidate for the AIST Distinguished Member and Fellow Award. A nominee has been submitted and endorsement letters have been prepared in support of the nominee.
Frank Petrek provided an overview of the Xtek Inc. facility in Sharonville, Ohio, located outside of Cincinnati, prior to the facility tour. Xtek was formed in 1976 from the Tool Steel Gear and Pinion Co., which began production in 1909. Since 1986, Xtek has been an ESOP company supplying the steel, aluminum, mining, shipyard and energy markets. The company has 400 employee-owners and has recently added Xtek Europe s.r.o., Midwest Service Center and Bradley Lifting Corp. to provide services of power transmission, industrial components and lifting equipment.
