Variable frequency drive for Crane & Hoist The variable frequency drive can be connected to the existing joystick controller of cranes fitted with cab controls. Programmable characteristic curves make the VFD possible to adapt operation perfectly to meet the specific requirements of the handling application. VFD in Crane and Hoist Applications VFD in Crane and Hoist Applications None of the overhead hoist and crane manufacturers, service and sales companies, out of the more than 1,500 we deal with directly, are using other than asynchronous motors. AC drives (VFD) for industrial crane and hoist movement | Danfoss Crane applications served by Danfoss drives. Hoist: Lifting and lowering of the load. Bridge, gantry, or long travel: The part of an overhead crane consisting of girders, trucks, end ties, walkway and drive mechanism which carries the trolley and travels in a direction parallel to the runway. Variable Frequency Drives | Hoists Direct Variable frequency drives are also commonly known as VFDs, adjustable speed drives or AC drives. Variable frequency drives are a type of AC motor controller that drive an electric motor by varying the frequency and voltage allowing for precise speed, energy efficiency and digital diagnostics. Our hoist and crane VFD offering includes full load …
