This crane was fairly simple to create as the majority of the crane is made of cylinders, so most of this model was just about creating and manipulating cylinders and other shapes into place.
I had to research a little into this because i had no real idea what type of crane i needed or what they looked like properly but after the research was done i had a fair good idea of what was needed and i started creating the crane by creating the verticle part of the crane so i knew how big i wanted it also the crane isnt complete, e.g. the base isnt there because the trailer wont show it so i thought it would be a waste of time creating something you dont see.
After i created the verticle part of the crane i made the horizontal part, this was pretty much done by just making two boxes and setting them a certain distance apart, i then made some more cylinders and set them to the size of the gap between the boxes. Next i faced them into the middle, between four of the cylinder e.g. four cylinders with the tops meeting at the center point between them, once this was done i then cloned the cylinders so that they were exactly the same.
Finally i added little parts of the crane, such as the controllers box and the boxes and cables that are used to pick things up. To create the controllers box i simply added a box and using the materails function i gave it a glass look, then added some small boxes to give it the look of being held together by the boxes.
This is the rendered version of the crane -
