The Cranes Technology Committee (CTC) held their fall meeting on Nov. 13, 2008, in Birmingham, Ala. After introductions by the attending members and a review of the AIST Anti-Trust Guidelines, seven new members were welcomed to the committee. A review of the International Crane Symposium was then discussed. Held in Košice, Slovakia, in September, AIST’s international conference attracted 100 attendees and was well accepted by all who attended. The committee felt that future international conferences should be planned and that the next International Crane Symposium should be held in Brazil in the fall of 2009. ArcelorMittal Tubarao has expressed interest in supporting the event. Next on the agenda was the review of the Crane Innovator of the Year award candidates. Bruce Constatine of EC&M championed Randy Creech for Mr. Creech’s work in promoting AC-sourced magnet control. Rusty Landis of TAG Inc. championed Micheal Heaney’s efforts to develop a training program at ArcelorMittal for the Crane Repairman of the Future. Rich Warriner of Virginia Crane Services championed Andy Montalbano of U. S. Steel–Gary Works for his Crane Maintenance Training Facility at Gary Works. Following a close vote, a winner was determined and the award will be presented at the 2009 AIST Crane Symposium in Pittsburgh, Pa., June 1–2. The program for the 2009 AIST Crane Symposium was also discussed. The title for the symposium will be, “Safety, Maintenance and Modernizations for EOT Cranes.” Twenty-four papers will be needed, and the members developed a list of 28 potential presentations: 10 mechanical, 10 electrical and eight safety-related. The final list will be determined by the officers of the committee and organized into a formal program. A small number of the presentations will also be presented at AISTech 2009 in St. Louis, Mo. Two technical sessions focused on EOT cranes were organized for AISTech 2009. It was determined that the next meeting will be held on Feb. 10, 2009, in Northwest Indiana so the meeting could be located close to many of the producer members of the committee. Included in the meeting will be a tour of ArcelorMittal Burns Harbor’s Crane Maintenance Department.
Following the general committee meeting, the members split into two subcommittees (Mechanical/Structural and Electrical) for topic-specific discussions on the Maintenance, Inspection and Repair of EOT Cranes Guidelines. The subcommittees reviewed their respective sections and developed a timetable for the members to complete their designated sections of the guidelines. The next meeting for the subcommittees to review their progress via Web and conference call was on Jan. 27.
On Nov. 14, 2008, the committee members were welcomed by CMC Alabama for a tour of the steelmaking facilities. Warren McWhorter, Mark Brune and Martin Schreiber welcomed the committee to CMC Birmingham. Mr. McWhorter provided an overview of the steelmaking and rolling facilities in Birmingham, and then proceeded to provide an excellent review of their safety record and how it was achieved. Additionally, he presented information on the EOT cranes at CMC and some of the unique features that their cranes possess. The members were then taken on a tour of the rolling mill, packaging and shipping department, the EAF pulpit, the continuous caster and the charge aisle. Following the tour, additional time was spent conducting a question-and-answer session with Mr. McWhorter and Mr. Brune regarding their cranes, how they are maintained, and improvements that they have made to keep their cranes operating.
The Mill Buildings Subcommittee of the Cranes Technology Committee met Oct. 9 in Cleveland, Ohio. Following introductions and a review of the AIST Anti-Trust Guidelines, the members began a discussion on the minimum requirements for inspections of steel structures. This discussion will become a paper presented at AISTech 2009 and will focus on existing structures. The goal is to set a standard for minimum frequency of inspections for steel structures in order that they can be maintained in a safe condition. The various points developed in the paper outline were discussed, so that a quality paper can be written. A general discussion followed, with members bringing up topics of concern as they relate to steel mill structures. The last item of business focused on the other internally developed paper for AISTech 2009, which related to crane loading and the coordination between AIST Technical Report No. 13 and the International Building Code. The next meeting for the Mill Buildings Subcommittee will be on Feb. 12, 2009, in Cleveland, Ohio.
The Mill Buildings Subcommittee (MBSC) of the Cranes Technology Committee (CTC) met on June 24 in Cleveland, Ohio, for their second meeting of 2008. After introductions, a review of the AIST anti-trust guidelines and staff announcements, the members discussed the future activities of the committee. In the new AIST Technology Committee structure, the former Mill Buildings Operating Committee became a subcommittee of the CTC. As a subcommittee, the membership is part of the CTC membership, but they will continue to meet independently from the CTC, create their own programming and host their own activities. To foster interaction between the subcommittee and the CTC, a subcommittee liason was created who would report any relavent CTC activities to the subcommittee membership. Joint meetings will likely be arranged at the annual AISTech meetings every spring. The MBSC then began discussions on developing their technical sessions for AISTech 2009, to be held in St. Louis, Mo., on May 4–7, 2009. The membership will create presentations internally for a three-hour, three-paper session. The papers will focus on hot metal duct design, mill building inspections and crane loading criteria in AIST Technical Report No. 13, Criteria for the Design and Construction of Mill Buildings. A discussion was also held on potential revisions to the technical report. The next meeting for the Mill Buildings Subcommittee will be Oct. 9, 2008.
The Cranes Operating Committee (COC) held meetings in both May and June. The May meeting was held in conjunction with AISTech on May 5, 2008. It was announced that Mike Urbassik, current vice chair and long-time member of the COC, had retired, and everyone in attendance thanked Mr. Urbassik for his years of service. A note was then made concerning the integration of the AISI Manufacturing Committees and the AIST Operating Committees. The new committee structure resulted in the COC changing its name to the Cranes Technology Committee (CTC) effective July 1, 2008. An election of officers was conducted, and a new chair was elected to serve the committee for the following year. The next item of business concerned Technical Report No. 6, Specification for Electric Overhead Traveling Cranes for Steel Mill Service, and new text proposed for Section 18.104.22.168. The proposed text change was brought forth at the sold-out 15th Annual Crane Symposium audience on June 1–3, 2008, to make them aware of the change in the specification. The CTC mission statement was reviewed and approved. An update on the International Crane Symposium in Košice, Slovakia, was given by Jerry Oberlander of United States Steel Corporation. The last item of business for this meeting was the presentation of appreciation plaques to the outgoing chairs of the COC and the Mill Buildings Operating Committee.
The next meeting for the CTC was held on June 1, 2008, prior to the start of the 15th Annual AIST Crane Symposium. The chair welcomed everyone to the meeting. An update was given regarding the program and attendance for the Crane Symposium. It was announced that the 2009 Crane Symposium will be held May 31–June 2, 2009, in Pittsburgh, Pa., and will focus on safety and safe work practices in maintaining electric overhead traveling cranes. An update was also provided regarding the International Crane Symposium, to be held on Sept. 23–26, 2008, in Košice, Slovakia, and which will include a tour of the U. S. Steel–Košice Works. Additional discussions took place regarding the revisions of Technical Report No. 6. The committee voted that the document should be revised every five years to keep it current with changes in the industry. It was also noted that work will continue on Maintenance, Inspection and Repair Guidelines for EOT Cranes. These guidelines will be educational in nature and geared toward any new personnel regarding best practice techniques in crane maintenance. The next meeting for the CTC will be Oct. 21–22, 2008, in Birmingham, Ala. Prior to the general committee meeting, an Electrical Subcommittee and a Mechanical/Structural Subcommittee meeting will take place to begin the revision of Technical Report No. 6.
January 16-17 , 2008 - The Cranes Operating Committee (COC) met on Jan. 16–17 in Memphis, Tenn., for their winter meeting. Following brief introductions by the 27 members and guests in attendance, the committee began their business meeting. Discussion was held on the status of the Cranes Innovation of the Year Award and an offer to include the Material Handling Operating Committee (MHOC) in the award process. The award criteria would be modified to include all material handling innovations and would be overseen by a joint subcommittee of COC and MHOC members. This suggestion was approved and will be brought forth to the MHOC at their next meeting for their approval. Since the award is still focused on crane innovation, a motion was made to proceed with nominating and confirming the Crane Innovation of the Year for 2008. Randy Creech of EC&M championed the cause for a digital DC drive installation in the slab yard hoist at SeverStal NA by Jodie Van Kammen. This innovation was selected for the award, which will be presented at the 2008 Crane Symposium in Pittsburgh, Pa. The status of the 15th Annual Crane Symposium program for June 1–2 was then provided. Presenters who were verbally confirmed will receive a written invitation to present at the symposium. Any open slots in the program were filled with a topic and a potential presenter. The chair and vice chair organized the program into an appropriate order to encourage sustained attendance throughout the schedule. The Subcommittee on Maintenance, Inspection and Repair for EOT Cranes presented a tentative table of contents for a guideline report being created. Individuals at the meeting were identified to develop each section of the report to expedite publication of the document. The Maintenance, Inspection and Repair Guidelines for EOT Cranes will serve as an educational tool and reference manual for anyone involved in EOT crane maintenance. An update was provided regarding an International Crane Symposium in Košice, Slovakia. A volunteer will approach the management of U. S. Steel Košice to determine if sufficient support exists at that facility for such a program. The committee will begin final planning for the international program upon confirmation from U. S. Steel. The members then discussed the COC session scheduled for AISTech 2008. The open slots in this part of the program were filled by committee volunteers. A brief overview of the AIST/AISI integration of steel-related technical committees was presented. The business portion of the meeting concluded with a motion to approach the AIST Mill Buildings Operating Committee (MBOC) for a joint meeting either at AISTech 2008 or at their fall meeting. A volunteer who is a member of both committees will discuss this item at the upcoming MBOC meeting. On Jan. 17, the members drove to Blytheville, Ark., for a tour of Nucor-Yamato Steel. The delegation was met at the facility by long-time friend and member Rickie Gallant. Following an overview of the facility, safety considerations and its production, a tour of the meltshop and caster was given, as well as a walkthrough tour of the beam rolling facility.
October 10-12 , 2007 - The Cranes Operating Committee (COC) and Sheet Rolling Operating Committee (SROC) held a joint meeting in Concord, Calif., on Oct. 10–12. The meeting kicked off with a tour of the rolling facilities at USS-POSCO.

The SROC remained to review and organize abstracts into four technical sessions for AISTech 2008, focusing on hot and cold rolling and surface inspection. Volunteers were also identified as chairs for these sessions.
On Oct. 12, the COC held a business meeting, beginning with a review of the outline created for a Maintenance, Inspection and Repair Guide for EOT Cranes Users. This guide will examine inspection practices and repair criteria for crane- and runway-associated components, in an effort to develop consistent guidelines on maintenance and when to repair and/or replace these components to enhance crane operation and safety, and to minimize unplanned downtime through improved reliability. Each section of the guide will be reviewed by individual working groups, who will organize and write an outline for that section. Also discussed was the 2008 AIST Crane Symposium, scheduled for June 1–3, in Pittsburgh, Pa. A survey of the 2007 Crane Symposium attendees led to the development of a list of presentation topics for the 2008 symposium. Potential presenters were indentified and will be contacted in the coming months to confirm their participation. Also discussed was the viability of an International Crane Symposium, which would be held in Košice, Slovakia, in 2008. It was determined that, to provide adequate planning for such an event, the event should be scheduled for the fall of 2008. Finally, volunteers were taken to present at the COC technical session at AISTech 2008. The next meeting is tentatively scheduled for Jan. 16–17, 2008, in Memphis, Tenn., with a tour of Nucor-Yamato Steel.
On Oct. 12, the Sheet Rolling Operating Committee (SROC) held a business meeting, first discussing plans for their AISTech 2008 technical sessions.

They discussed several options for future meetings and started to develop a plan to get more participation from producer members. A review of the presentations for the Hot Rolling Training Seminar was to be held in November to ensure elimination of any overlap between presentations. The SROC also planned to hold a meeting during the Hot Rolling Training Seminar in February.
May 9, 2007 - The Cranes Operating Committee (COC) met on May 9 at AISTech 2007 in Indianapolis, Ind. Following introductions, AIST staff announcements and an update on membership, the committee recognized Charles Totten, Morris Material Handling–P&H, who became an AIST Distinguished Member earlier that day at the AISTech 2007 President’s Award Breakfast. After re-electing their current officers to an additional term of office, the committee heard an update on the sold-out 2007 AIST Crane Symposium, which was held in Cleveland, Ohio, June 10–13. Geoff Zimmer of CMC Steel South Carolina was recognized at the meeting and at the Crane Symposium for being the inaugural Innovator of the Year for his presentation entitled, “Solid-state Magnet Control in Improve Scrap Handling.” The COC then discussed the possibility of a joint effort with the Crane Manufacturers Association of America (CMAA) to produce a maintenance and inspection guide for electric overhead traveling cranes. The meeting concluded with approval of the current COC mission statement. Dates and locations for the COC’s fall and winter meetings were discussed and were to be confirmed at the committee’s meeting on June 10 in Cleveland, Ohio.
The Cranes Operating Committee met again on June 10, 2007, in Cleveland, Ohio, prior to the start of the AIST 14th Annual Crane Symposium. Following member introductions and staff announcements, the members began discussion on the 2008 Crane Symposium. With the event being held outside of Pittsburgh, Pa., for the first time, it was agreed that the attendees of the 2007 symposium should be surveyed to garner their opinion on the location of future symposia. The results will be tabulated and submitted to the committee’s leadership before a final decision is made. The presentations for the 2008 symposium will also be based on the response from the attendees regarding current topics of interest in the crane industry. Next, a discussion was held on the status of any AIST Technical Reports that relate to overhead traveling cranes. Many of the reports were printed prior to the widespread use of computers and were not available electronically. Therefore, they were difficult to update. A project has been undertaken to put the reports into electronic format. TR No. 1A on AC Mill Motors, TR No. 4 on Alloy Sling Chains and TR No. 11 on Design of Mill Motor Brakes required no revisions. TR No. 8, Insulated Conductors for Mill Auxiliary Motors, was recently revised and prepared for printing. TR No. 7, Design of Ladle Hooks, required a clarification on symbology and the figures, and would need to be revised prior to being reprinted. Also, the 1991 revision of TR No. 1, DC Mill Motors, did not contain the extensive listing of 600 frame DC Motors that were listed in the 1957 printing. The 600 frame motors, while not being manufactured today, were still plentiful in service and were being remanufactured as replacements. A revised report will contain information for both motors and will be available as a supplemental appendix in the next revision of TR No. 6, Specification for Electric Overhead Traveling Cranes for Steel Mill Service. The next item of business was a discussion on the progress of a user-based EOT crane maintenance and inspection guide. The subcommittee responsible for preparing this document will continue their efforts to create this document. A discussion was then held regarding a request by U. S. Steel to bring the AIST Crane Symposium to their facility in Košice, Slovakia. Charlie Totten, past chair of the COC, will meet with representatives from U. S. Steel to determine their technological needs and how standards and laws governing crane programs in North America will apply to the standards and laws in Europe, as well as the relevance of the North American technology to the Slovakian industry. The committee voted in favor of conducting the program in Slovakia based on the outcome of the meeting. The COC’s next meeting, to be held in Concord, Calif., will include technical discussions on crane technology and a tour of USS POSCO in Pittsburg, Calif.
