Safety for EOT Crane Wireless Remote Control
Laercio Neves, Laird
Discussion will focus on the safety of wireless remote control and safety standards for wireless communications equipment. Wireless remote control for EOT cranes is the control of a machine by a person using a mobile operator control unit (OCU) that is communicating with a machine control unit (MCU) mounted on the crane. Being restricted by the bonds of wires or needing to be at a control panel can reduce safety and productivity. Wireless remote control enables an operator to be positioned at a safe location and have a better view of the task, with the ability to react instantly to any required changes that are needed. Remote-control solutions enable safer operating practices with less worker motion, and these ergonomic workflows lead to increased productivity.

8:45 a.m. 

Increased Operational Safety Through Lifting Magnets
Jose Maria Rosales Angulo, SGM Gantry S.p.A.
This presentation will discuss increased operational safety through the use of industrial lifting magnets, promoting the reduction of human exposure with steel, delimiting overhead cranes trajectories and out-of-bounds areas. New safety devices developed for lifting magnets in recent years will be covered.

9:15 a.m.

Remaining Lifetime Prediction of Structures and Components

High-Risk Cranes and Casting Cranes: Safety and Cost Savings Through the Use of the Double Kinematic Chain in Lifting
Esteban Mondragon, JASO Cranes
The presentation will focus on how to prioritize safety and productivity within the steelmaking process; in particular, during the tapping of liquid steel through the design of cranes with mechanical and electrical redundancies in the lifting and translation systems. A real example of the economic savings and improvement in safety and productivity achieved through the implementation of this system will be shown.

10:45 a.m.

Rope Drum and Sheave Wheel Fundamentals
Andrew Salach, Xtek Inc.
The presentation will discuss the basic rope drum design with focus on buckling of the rope drum shell and contact pressure of the wire rope. Further wear areas in rope drums will be reviewed such as grooves, lands between grooves, bearing seat diameter and seal journal. Additionally, the wear issues of drum gear, wire rope and sheave wheel addressed. In conclusion, the increased hardness of the rope drum and shave grooves versus the wear resistance will be discussed.

Ore Bridge Upgrading
Alberto Antonielli, Ternium Siderar
In 2010, Ternium Siderar upgraded one of the two ore bridges existing in the Savio Plant, Ramallo, Buenos Aires, Argentina. This upgrading consisted of structural modifications, trolley replacement and the change of electrical technology, going from DC to AC, with inverters. This presentation describes the objective of the project, the works done and the successful results of the renovation after more than six years of operation.

3D Interactive Virtual Safety Training Simulator
Armin Silaen, Purdue University Northwest
In order to make safety training more efficient and effective, a 3D Interactive Virtual Safety Training Simulator has been developed, which provides a virtual environment in which steelworkers are guided through a task while adhering to standard safety procedures. Using this, steelworkers can intuitively see how their choice of personal protection equipment and their behaviors in the work environment can impact their safety during operation. This may decrease the possibility of suffering injuries or fatalities at work.

2 p.m.

Don’t Let Your Cranes Drop Hot Metal Ladles
Charlie Totten, T&M Equipment Co.

2:30 p.m. 

Advanced Safety Techniques for Hot Metal Cranes
Michael Birch, international business development and facilities manager

State-of-the-Art Anti-Collision and Positioning Systems for the Metals Industry
Edgardo LaBruna and Ariel Gonzalez, Janus Automation LLC
The steelmaking industry environment presents harsh conditions like dust, heat or vibration. That’s why the implementation of reliable anti-collision and positioning system have always been a challenge. This presentation will discuss several successful implementations in this area.

4:30 p.m. 

Installation of Computers on Steelmaking DC Cranes for Data Collection, Improved Communication and Equipment Protection
Brad Hebert, ArcelorMittal Burns Harbor
The exchange of information between crane operators and their management team is a challenge in every industrial setting. Crane operators typically work alone and depend on radio communication or hand signals to convey information. Unfortunately, valuable information can be miscommunicated or lost in these exchanges. Integrating technology is one of the tactics being implemented to improve the exchange of information between cranes, the crane operators, operations management and the maintenance group at ArcelorMittal Burns Harbor steel producing. As a result, each of the cranes mentioned above currently use a computer mounted in the cab and other hardware to transmit data entered by the crane operator or collected by the electronics on the crane to a central database. This presentation describes how the integration of technology has a positive impact on safety, communication and reliability.

5 p.m.

Cabin Replacement at the Crane G44 at the Meltshop of Tenaris Siderca
Daniel Garvich, Tenaris Siderca

5:30 p.m.

Focus on Cranes: Level Change at Assets Management
Antonio Henrique dos Reis Pena, ArcelorMittal Tubarão
In a challenging moment of production increase, organization changes were made in regard to cranes asset managements at a steel plant area that presented performance and maintenance indicators lower than expected. A deep restructuration process was started with a focus on cranes by approaching maintenance plan review methodology based on studies of reliability-centered maintenance, failure modes and effects analysis, equipment criticality, and a management based on performance and necessities of the assets.

Life Prediction in Industrial Equipment
Armin Silaen, Purdue University Northwest
Modern equipment design methods make use of computer-aided engineering software and computational numerical analysis such as finite element analysis to obtain a high degree of precision during the design process. Engineers can make use of this precision to more accurately predict the system response to operating conditions at either the assembly level or within individual components. The focus of this study is the development and application of a methodology that will allow for the advantages of the modern design process to be applied to existing equipment.

Anti-Crab System Conclusions
Daniel Garvich, Tenaris, Argentina
In early 2013, number GL71 and GL72 EOCTs were revamped, replacing the whole bridge structure, mechanisms and electric system. Taking into account the many existing problems with the runway (variations in the span due to problems with the building structure), producing excessive wear and tear of wheels flanges, it was included a new electronic “anti‐crab” system, to avoid skew and drift. Now, after four years, it is possible to make conclusions about the operation of this system, which are presented in this paper.

High-Speed Data Transmission Rails for Process Cranes
Mikel Aguirre, Conductix-Wampfler Latin America
In the new generation of process cranes, the possibility of remote control operation has, in the last few years, been a very highly requested topic. The emergence of new rail developments in which a simple bar system with high-speed data transmission (video + audio + positioning + high reliability + safety), having a capacity of 100 Mb/second on up to 500-m runways, can solve these requests. The system fits within the same dimensions of a standard four-pole electrification rail system, but with enhanced benefits.
