During the 2011 Japanese nuclear accidents at the Fukushima plant, multiple Putzmeister concrete boom pumps were flown to Japan from locations around the world. After the initial success of a M58-5 unit, additional M62-6s and 70Z's were transported to Japan on-board chartered Antonov An-124s, the world's second largest cargo plane. The 70Z is the world's largest boom pump, able to reach over , and able to be controlled remotely from away. The pumps will be deployed to try to stabilise the four reactors with additional water pumping capacity.
