Techincal drawing of a Crane Hook (DIN Standard)

One of my favourite and most fun drawings to do. Even if it was a project from high School, it shows how a simple thing like a Crane Hook have many features to be shown so that it can be made corectly. As you can see the drawing has many dimensions, but they all are clear to read, which is and advantage also they are needed couse of the crosing from one radius to another changes.
