What is a lifting plan and how many types of lifting plans are there? how to make critical lift calculation?

Lifting Plan - a Lifting Drawing plan and Technical adherence of the equipment's sets of instructions. 

Types of lifting plans - (Rigging Tackle Arrangement) Crane Lifting Plan, Gantry Crane Lift, Jacking, Shiplift (Ship Lifting), Skycrane (Chopper Lift), Antonov ("HeavyLift Plane" stowage/load plan), Transport Arrangement and many other forms of lifting. 

How to make a critical lift calculations - before any critical lift calculations, the procedure of lifting should first have to fall on that category ("critical lift").
