What weapons (like a catapult) did the Mongol-Tatar soldiers have?

The Mongol-Tatar army had a lot of different structures and devices for war, including weapons for storming cities. The number of weapons that they used to storm cities included: battering rams (mobile and portable), catapults, ladders, ropes, mobile towers, etc. The use of siege weapons was borrowed by the Mongols from the Chinese states with which they fought. Indeed, in China, various devices were very often used to storm fortresses. Thus, when the Mongols approached the border of Russia, they were very well aware of the methods of storming cities.
