Shanghai Zhenhua Heavy Industries (ZPMC), the world’s largest port crane manufacturer, has denied claims from U.S. politicians that its equipment poses a cybersecurity threat, according to Splash 247. 

Recently, a U.S. congressional probe raised security concerns about communications equipment on Chinese-built ship-to-shore cranes at American ports, including cellular modems that could be remotely accessed, cited in a February 21 revised advisory from the U.S. Department of Transportation Maritime Administration.

The Biden administration recently announced it would replace the nation’s Chinese-built port cranes with Japanese ones, at a cost to the American taxpayer of $20 billion over the next five years, because of concerns they could be fitted with spy devices.

“ZPMC takes the U.S. concerns seriously and believes that these reports can easily mislead the public without sufficient factual review,” ZPMC said in a filing March 10, stressing: “The cranes provided by ZPMC do not pose a cybersecurity risk to any ports.”
