Perhaps no other technological development in nearly 40 years has done more to revolutionize overhead crane design than the AC Variable Frequency Drive (VFD). Today’s Variable Frequency Controls and Flux Vector Motor Controls have become the industry standard for crane control. Recent improvements in drive technology, such as a new generation of Insulated Gate Bipolar Transistors (IGBTs), sensor-less vector control, powerful microprocessors with flash memory, and improved algorithms, have allowed the downsizing of the power platforms and the inclusion of many high-performance features.
There are numerous benefits of using a VFD to control a hoist or crane, including:

Magnetek’s collision avoidance systems can help prevent accidents before they happen, protecting people, the facility, and the cranes. Our collision avoidance systems prevent crane-to-crane and crane-to-end stop collisions which increases operator safety and reduces system maintenance.
Magnetek offers three collision avoidance systems which can be applied to all types of overhead cranes or monorails with adjustable frequency drives, soft starters, or contactor controls. Multiple configurations are available so customers can choose the exact functionality, size, and style to fit their application needs. All Magnetek’s collision avoidance systems are rated IP65 or better. The collision avoidance systems are “fail-safe”, which means that if the sensor would lose power, motion of the crane would be stopped and restricted.
