Variable Frequency Drives
VFD's can now be purchased from select vendors that are specifically designed for the crane and hoist industry. These drives, a combination of hardware and software, provide automated control of all hoist and bridge motions.
By incorporating VFD's, lifting and materials handling becomes much safer and more effective through providing almost infinite motion variability. And finally, the inclusion of VFD's in a lifting application will extend the life of a crane system by avoiding rapid starting and stopping which places the most immediate and significant strain on a system. This almost eliminates the wear on the brakes.
VFDs are available for both new systems and can be retrofitted to your existing hoisting system that needs modernization.
