Introduction and Opening Remarks

8:15 a.m.

Innovations in Crane Technology
Mike Martin, Trutegra
This presentation will cover emerging technologies to aid operators with manual and semi-auto cranes as well as new technologies for fully automatic operation. Manual/semi-auto new technology includes anti-sway for non-variable frequency drive cranes, obstacle avoidance/no-fly zones, and the use of augmented reality for remote operation. New automated crane technology includes automatic bucket crane digging, real-time obstacle avoidance of moving material, automated eye-to-the-sky coil handling, and programmable logic controller-based 3D mapping of bulk inventory.

8:45 a.m. 

Case Study: Automated Scale Pit Crane System at Nucor Steel
Rick Emmer, CMCO Automation, and Jared Gilpin, Nucor Steel–Berkeley
This presentation explores a recent crane automation project performed at Nucor Steel–Berkeley. The steelmaking facility was looking to improve their mill scale clarifying process. Working together with Columbus McKinnon’s Automation Division, Nucor Steel–Berkeley was able to automate the scale removal process and reduce maintenance time and costs. The presentation will delve into the solution to this challenging application and explain the automated solution designed and implemented to improve safety, uptime, and productivity.

Use of Non-Contact Sensors to Provide and Improve Safety and Reliability in the Operation of Overhead Cranes
Steven Lubeck, Laser-View Technologies
Traditionally, overhead cranes have utilized mechanical means of providing safety features to protect equipment and personnel. Some examples are end stop limits, crane-to-crane spacing, no-fly zone perimeters, obstacle detection, temporary maintenance stops, and hoist side pull and anti-snag. Several sensor technologies exist that are applicable to provide non-contact solutions to applications previously handled with mechanical methods. Non-contact solutions oftentimes are more reliable and can provide a level of operational flexibility that is not possible solely with traditional methods. This presentation will provide descriptions of the various non-contact sensing methods commonly used, along with a comparison of advantages and disadvantages of each technology. New techniques will also be discussed. Emphasis will be placed on the level of reliability and safety provided by each method, along with the relative levels of complication related with the integration. Examples will be provided with the intent of sparking interest in creative approaches to using sensors on cranes to establish safer and more reliable operation.

11 a.m. 

Optimizing Material Handling
Rob Loomis, InVekTek LLC
The throughput of a plant is throttled by the skills of the least experienced crane operator. The recent resurgence of the steel industry and the sudden increase in new hires has magnified the need to help new crane operators get up the learning curve. One industry leader reported it incurs US$1.5 million per month in product damage due to operator error and it’s getting worse. While viable automation is still not yet attainable, there are new technologies that can dramatically save money by accelerating the learning curve of new crane operators, reducing the number of and severity of collisions and improving overall productivity.  

11:30 a.m.

Remote Control of Two Overhead Cranes of a Scrap Yard
Steven Friscia and David Willick, Schneider Electric​          
The main objective of this presentation is to provide an automated remote control management solution to drive existing scrap yard from a control room. The project is a turnkey project including detailed risk analysis for the safety operation, DC to AC conversion and crane electrical revamping, closed-circuit television remote control system, semi-automated functionalities, and advanced crane system expert for diagnostic and supervision. The discussion will include a description of the challenges during design, engineering and commissioning of this project of two remote cranes with an electromagnet for scrap handling.
