When comparing variable frequency drives (VFD) to 2-speed control for use in cranes and hoists, there are a variety of factors you should take into consideration. These range from load control and speed adjustment to efficiency and extended hoist life. In this blog, we will compare the two to show you the benefits of VFD crane control over 2-speed.
GREATER SPEED ADJUSTMENT
IMPROVED LOAD CONTROL
INCREASED HOIST LIFE
VFD control provides many benefits as compared to 2-speed control in your crane or hoist. By using VFD control throughout your facility, you not only prolong the life of your equipment and save money on energy costs, but you can standardize the type of motor used on equipment for a lower total cost of ownership.
This online course includes discussions of basic principles and operation of Magnetek’s industry-leading IMPULSE® AC variable frequency drives for crane applications.

The CM Lodestar VS is now available with Intelli-Connect™ Diagnostics and Analytics technology. Intelli-Connect enables quick and easy programming, maintenance, monitoring, and troubleshooting of the Lodestar – all from a tablet or smartphone.
How does it work? Using the Intelli-Connect Mobile and Mobile+ apps, you can
wirelessly access detailed information right from the plant floor, without the need to attach a programming cable. Intelli-Connect is available as an option on all new Lodestar VS units or in a retrofit kit for units already in service.
When choosing a variable frequency drive (VFD) for your crane or hoist application, we recommend using a crane-specific VFD and not a general purpose VFD. Why? Using a crane-specific VFD can have a significant impact on the safety, uptime, and productivity of your crane application, and can get you up and running quicker and easier.
