Magnetek Variable Frequency Drives Upgrade Molten Metal Overhead Crane and Dramatically Improve the Class F Crane Reliability!
How many times have you bought something, only to later think “Wow, that was a terrible idea”, or “I sure would do that different now knowing what I know”? For one of our customers, that is exactly what happened.
Only a few short years after purchasing a new 65/20-ton Class F Molten Metal Overhead Crane, the customer could no longer suffer the downtime and costs involved caused by the Square D variable Frequency Drives. Being familiar with Magnetek Controls and Service, the customer requested we develop a plan to replace the Square D drives with Magnetek Series 3 drives.
Original Square D Controls
Because of the plant’s requirement for operation, and the physical size of the drives this was not your typical installation. Working almost non-stop Dane Vance and crew were able to gut the control house and reinstall the new Magnetek controls. I should note that on the day the crane was placed in our hands, 3 of the 4 Square D drives were already tripped out. This crane needed help “STAT”!
You think you have seen sticker shock before? At least the phone number is toll free!
After a “Dane Vance Crane Day Spa”, this crane was placed back into [real] operation. Within the first 4 hours the operators and maintenance personnel were all thrilled with the non-stop operation of the crane.
New Magnetek Drives and DBU’s in place and ready for abuse!
