Tadano’s announcement comes just days after the president of United Against Nuclear Iran (UANI), Mark Wallace, wrote in a Los Angeles Times op-ed that the company exports cranes to Iran which have been misused in what he called the regime's "execution binge."

UANI praised Tadano’s decision to cut ties with Iran.

"Tadano is a responsible corporation and its decision is another example of an international company taking the right action in the wake of UANI’s Cranes Campaign,” said Wallace in a statement. “UANI hopes that even more crane companies will end their business in Iran as the bright light of world attention is cast on Iran’s barbaric execution binge."

United Against Nuclear Iran first brought the issue to the attention of the crane manufacturer in May. In a press release, UANI named Japanese company Tadano and another company, Furukawa UNIC, as providers of hydraulic cranes to Iran. According to the release, photographic evidence shows that Iranian citizens have been executed using cranes from both Japanese companies.

"As part of its newly launched "Cranes Campaign," UANI is highlighting the Iranian regime's abhorrent public executions by hanging from construction cranes," UANI said in the May press release. "The disturbing reality that these cranes are coming from Western and Asian companies."

Terex Corp. and Caterpillar, two top U.S. construction manufacturers, and Japan's Komatsu have terminated business ties with Iran.

According to Amnesty International, more than 135 executions have taken place in Iran just this year. At least 13 of those executions were public hangings.
