Who makes it
5 companies produce variable frequency drive (vfd) systems for cranes.
German industrial conglomerate. SINAMICS drive family (S120 series) manufactured at the Erlangen Electronics Factory (GWE plant, named WEF Digital Lighthouse). SIMOCRANE software provides crane-specific control layered onto SINAMICS. Dominant crane drive supplier for ZPMC-built port cranes globally. SINAMICS is also used in nuclear power plant cooling, rail traction, and wind turbine applications — same hardware platform across critical infrastructure.
Swiss-Swedish electrification and automation company. ACS880 crane drive series with built-in crane control program covers STS, RTG, RMG, and grab ship unloaders. Primary drive manufacturing at Pitäjänmäki, Helsinki, Finland — the world's largest drive factory. ABB drives division also covers wind energy, EV charging, data centers, and marine propulsion — same hardware platform across multiple critical supply chains.
Danfoss acquired Finnish VFD manufacturer Vacon in 2014 for ~€1.5B. Vacon's NXP drives are the platform for crane applications. Danfoss claims 100,000+ crane drives deployed globally covering chain hoists to 10,000-ton crane vessels. VACON NXP System Drive and VACON NXP Common DC Bus are the primary heavy crane products. Manufacturing at Vaasa, Finland (Vacon heritage plant) and Graasten, Denmark (Danfoss drives). Combined Danfoss+Vacon LV drive revenue represented ~10%+ of global LV drive market at time of acquisition.
US industrial automation company. Allen-Bradley PowerFlex 755T drives are marketed as the only VFDs combining TorqProve technology, anti-sway, regeneration, and Premier Integration for crane applications. Power range 0.37–4,550 kW. Primary market is North American industrial and port cranes. Manufacturing at Milwaukee, Wisconsin and Monterrey, Mexico.
Columbus McKinnon acquired Magnetek in 2015. Magnetek (IMPULSE series VFDs) is the self-described "leading manufacturer of drives for the hoist and crane industry" in North America. Focus: industrial overhead cranes and hoists. New IMPULSE G+/VG+ Series 5 launched January 2024. Note: Yaskawa directs crane/hoist customers to Magnetek, indicating a partnership rather than direct competition. Less relevant to large port cranes (STS/RTG); primary market is manufacturing facility overhead cranes.
