Yale® Cable King™ Hoists Modernize Heavy Lifting in a Highly Corrosive Environment

Overview

In the volatile environment of a galvanizing operation, steel moves through extreme heat and corrosive chemicals, demanding robust lifting equipment capable of precise performance. The end user had relied on Yale® Cable King™ hoists for years, but as the fleet neared the end of its lifecycle, it became clear that a comprehensive modernization effort was required. Updating the crane controls and replacing aging units with heavyduty equipment would ensure the operation could continue running safely and efficiently in one of the industry’s harshest environments.

The Challenge 

• Replace existing 30-year-old Cable King hoists at the end of their lifecycle age and experiencing wear and tear from long-term use in a harsh, corrosive environment 

• Modernize crane controls from a 2-speed control to one inclusive of advanced control and monitoring capabilities 

• Avoid load swing from tank to tank that may occur when using a 2-speed crane control on the trolley  

• Improve safety for operators and equipment during lifts to prevent injury to people, equipment, and load damage 

The Solution 

Columbus McKinnon worked closely with the end user and channel partner to understand the galvanizing process’ unique requirements and delivered a tailored solution that modernized the process while enhancing safety and efficiency. 

• Upgraded all existing hoists to modern, high-performance Cable King hoists capable of precise lifting 

• Added Cable King hoists to an existing system for an even more robust setup, resulting in enhanced performance and increased safety to equipment, operator, and facility 

• Utilized spare Cable King hoists during the modernization process to reduce downtime 

• Integrated IMPULSE® VFDs to enhance operational safety and significantly extend the lifespan of equipment, delivering both protection and performance 

• Upgraded Magnetek Control Panels to NEMA 4X rated and stainless steel for additional protection in the corrosive environment 

Cable King electric wire rope hoists come standard with a range of performance-enhancing features to extend their lifespan and minimize downtime and costs due to maintenance, even in harsh environments. Each unit includes a redundant braking system ensuring secure stopping and reliable load holding. 

Building on this robust foundation, Columbus McKinnon, a one-stop source for both lifting and automation technology, equipped the Cable King hoists with integrated Magnetek® IMPULSE®·G+/VG+ Series 4 Variable Frequency Drives for the control system for a smarter, safer operation. This powerful combination gives the end user real-time access to critical performance data, including motor temperature, continuous detection of hoist overload conditions, motor speed, and more, while providing advanced diagnostics, such as trending data, event history, and equipment usage history. This comprehensive information empowers the end user to detect and correct potential issues before they happen so their operation can continue with minimal downtime. 

Through strategic partnerships, expert consultation, and advanced product integration, including Yale Cable King Electric Wire Rope Hoists and Magnetek VFDs, Columbus McKinnon played a critical role in modernizing the end user’s galvanizing operation. The robust, high-performance lifting solution was tailored to the unique demands of the corrosive environment and not only enhanced safety, operational efficiency, and precision but is a durable, high-performance solution that they can rely on for years to come.
