Heavy tank
The Char 2C was one of the largest tanks ever produced. At the start of World War II, France and the Soviet Union were the only countries to have inventories of heavy tanks, such as the Char B1, T-35, and KV-1. The Matilda II was designed under the British infantry tank concept which is similar to the heavy tank having thick armor and weighing more than their other tanks. It’s usually separate because they have less firepower with their cruiser tanks (comparable to mediums) at the time having the same main armament but more machine guns. Later war examples were the German Tiger I and II, as well as the Soviet IS series. Note that "heavy" versus "medium" is more a question of tactical roles than weight; the Panther, for example, was a "medium" tank that outweighed most Allied "heavy" tanks.
Timeline of the Fukushima Daiichi nuclear disaster
Workers pump radioactive water from a utility trench near reactor 1 into a storage tank near reactor 4. Water in the condensers for reactors 2 and 3 is shifted to outside storage tanks so that the condensers can remove more contaminated water from inside the reactors. The world's largest concrete pumping truck is shipped from the United States to Fukushima. The truck has been slightly modified to be able to pump cooling water initially, then will later possibly to be used to pump concrete for any eventual permanent containment structure. A 62-metre-tall pumping truck, donated by Chinese manufacturer SANY is also used.
