A siege tower is a tower on a wheeled platform to allow the attackers to climb up it and over the castle walls. Accurate doesn't come into it.
Sieges could last many weeks or months, depending on the quality of the siege artillery, the usage of siege towers and scaling ladders (both of which did not require destroying defences before invasion) as well as supplies for the attackers and the defenders. Attrition due to a lack of food supply or disease were often reasons for sieges to last a much shorter time than they would have done otherwise.
