Both documents require additional updates to the mechanical sections prior to finalization. The CTC then heard presentations made by the champions supporting their nominations for the 2013 Crane Innovator of the Year. Following a vote by the members in attendance, Jim Lang of Konecranes was recognized for his work on a 10-year survey of crane safety. The CTC then also recognized James Salisbury, ArcelorMittal Dofasco Inc., who will be given the AIST Distinguished Member and Fellow Award during AISTech 2013. Salisbury has been a tireless supporter of the CTC and has provided input and support to many individuals regarding EOT cranes in any industry. Following the meeting, Scott Waine, SSAB Mobile, provided an overview of the SSAB Mobile facility and its crane maintenance program. Waine hosted the CTC members for a tour of the facility, providing an opportunity for the members to visit the meltshop, caster, rolling and shipping facilities at SSAB Mobile. The next CTC meeting will be held immediately prior to the 20th Annual Crane Symposium on 9 June 2013 in Pittsburgh, Pa.
The Cranes Technology Committee (CTC) held two meetings recently leading up to the 19th Annual AIST Crane Symposium. The first meeting was held on 7 May 2012 during AISTech 2012 in Atlanta, Ga. The second meeting was held on 10 June 2012 in Pittsburgh, Pa., immediately preceding the Crane Symposium. These short business meetings ensured that the committee membership was well informed and had a voice in the activities of the committee. A main topic in both meetings was the status of the AIST Crane Symposium. The 22 presentations scheduled for the symposium were confirmed, and, as needed, substitutions were identified. Another important topic discussed was the revision to the AIST Technical Report No. 6 — Specification for the Design of EOT Cranes for Steel Mill Service. The report is currently planned for re-publication in 2013, and the CTC is organizing all of the revisions to the text. The CTC is also working to finalize The Maintenance, Inspection and Repair Guide for EOT Cranes. Other business handled during these meetings included the election of officers for 2012–2013; approval of the CTC mission statement; acknowledgment of Terry Fedor Sr., CTC member, as a 2012 AIST Distinguished Member and Fellow; the solicitation of presentations for the 20th Crane Symposium, which will be held 9–11 June 2013, and the planning of the CTC 2012 fall and winter meeting locations. 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.
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. During the tour, the members visited the following areas: tooth grinding, wheels and small gears, large gears, geared spindle coupling, rolls, heat treating, service and reconditioning, and shipping.
After the tour and a lunch, the committee split into two subcommittees (Electrical and Mechanical/Structural) to continue their efforts to complete the Inspection, Maintenance and Repair Guide for EOT cranes and to begin revisions to AIST Technical Report No. 6. The next CTC meeting will be held on 7 February 2012. The location will be determined once the tour location has been approved.
The Cranes Technology Committee (CTC) met on 12 June 2011 in Pittsburgh, Pa., immediately prior to the start of the 18th Annual Crane Symposium. Twenty-seven committee members and guests were in attendance. Mike Urbassik, CTC chair, opened the meeting, introductions were made and a recorder of the meeting minutes was confirmed. The AIST staff announcements and Antitrust Guidelines were read and noted. Charlie Totten provided a review of the 18th Crane Symposium being held immediately following the meeting, where 220 attendees were registered. It was noted that there were a couple of late presentation cancellations. Members volunteered to fill the program. The committee also began soliciting presenters for the 19th Annual Crane Symposium, to be held in June 2012.
The committee then began a discussion on the current criteria and procedure for nominating and selecting the Crane Innovator of the Year Award winner. A review of the procedure was read, and suggestions were made regarding the proper balance of voting levels. It was determined that, in the future, the criteria would be divided equally among four categories: New Technology, Industry-Wide Application, Potential Benefit to Crane Users and Leadership/Novelty. John Austin was recognized during the meeting as the 2011 winner, and a formal presentation was to occur on Tuesday, 14 June, during the Crane Symposium.
The committee continued with business from previous meetings regarding the CTC mission statement, as well as two proposed revisions to the statement. After the discussion, the committee voted to maintain the wording as currently written. Additional unresolved business was the proposal to consider a Crane Symposium in Brazil. A request was made to a few Brazilian steel companies regarding crane issues within their facilities, and the reply was that structural issues are a concern in older cranes. As it was a small sample for the request, additional requests will be made to ensure proper programming. CTC members conducting business in Brazil will discuss with their customers how the committee can serve the Brazil EOT crane community.
The chair then opened the floor for additional discussion. A proposal was made to update the current issue of AIST Technical Report No. 6 — Specification for the Design of EOT Cranes for Steel Mill Service. Individual subcommittees will begin to meet to accomplish the task in a timely manner. The committee will include in this program the revision to the Reference Handbooks for EOT Cranes, which is currently out of date and out of print. Other items discussed were the nomination of CTC members for the AIST Distinguished Member and Fellow Award and the recognition of Damon Burrow as the CTC vice chair. The next meeting will occur 4 October 2011 in Cincinnati, Ohio, and will include a tour of Xtek Inc.
The Cranes Technology Committee (CTC) met on Monday, 2 May 2011 at AISTech 2011 immediately following their technical session. Mike Urbassik, vice chair, in the place of Bill Wagner, chair, welcomed everyone in attendance to the meeting. As recognition of the efforts of the authors from the morning session, Urbassik and Charlie Totten asked the authors to stand and receive their authors’ certificates before the committee membership. AIST Antitrust Guidelines were read and introductions were made of those in attendance. 2011–2012 officer elections led the meeting. Mike Urbassik was nominated and approved as chair. Damon Burrow was elected as vice chair. The 18th Annual Crane Symposium schedule was then reviewed, and it was noted that the program had two cancellations which would be filled by volunteers. The Gateway Clipper Cruise would again be part of the activities for the symposium. Next on the agenda was a review of the CTC mission statement. Tom Berringer had offered a modification to the mission statement to recognize the participation of the Mill Buildings Subcommittee in the committee’s activities and to recognize the Crane Symposium as a key activity of the committee. After discussion and revision, the mission statement was to be reproduced for final vote at the June 2011 meeting. Members also provided updates concerning the Maintenance, Inspection and Repair Guide for EOT Cranes. The Electrical section of the report is nearly complete while the Mechanical/Structural section requires a few additions prior to submittal for review. Once the guide is complete, the CTC will begin revision to Technical Report No. 6 as well as a review of the Handbook for EOT Cranes Volumes 1 and 2 to ensure the proper, relevant material is published in those volumes. At the conclusion of the meeting, the committee voted to meet in October in Roanoke, Va., in conjunction with the AIST Southeast Member Chapter annual meeting.
The Cranes Technology Committee (CTC) met on 16 Feb 2011 in Memphis, Tenn., for their winter meeting.
