All lifting jobs feature a weight that requires to be moved from point A to B, and mostly, B is further away than A. How heavy and how far away, primarily, dictates the size of crane needed.

Given this, engineering of any lifting job starts with the crane charts. These strange looking tables of numbers indicate the size of load a crane can lift, how far away it can place the load, how high it can be lifted, and even how much ballast you need to send to site for a given lift.
